NEVER POINT your firearm at anything you do not intend to shoot.
KNOW YOUR TARGET and beyond.
USE EYE & EAR PROTECTION when shoong.
DO NOT TOUCH the trigger unless you are ready to fire.
DO NOT RELY on the firearm’s safety - it should only be considered a supplement to safe
firearm handling.
NEVER LEAVE a loaded firearm unaended.
ONLY USE AMMUNITION designed for your firearm. Failure to use the proper caliber
ammunion can damage your firearm and may result in injury or death.
ONLY USE QUALITY commercial ammunion that is in good condion. Using corroded,

• This operang manual covers Windham Weaponry models chambered for a wide
variety of ammunion calibers. Be sure that you only use ammunion of the caliber
marked on the barrel of your rifle. These are lightweight, gas operated, air-cooled,
magazine fed rifles that operate in semi-automac mode (meaning that each me the
trigger is pulled, a single round will fire, unl the magazine is empty.
• On all models, the upper and lower receivers are easily opened for cleaning and
inspecon. Upper and lower receivers are machined from forged 7075 T6 aircra
aluminum or molded of 40% carbon fiber content polymer composite.
• Most Windham Weaponry models feature fully adjustable rear sights and elevaon
adjustable front sights. Some models are designed to allow the owner to add their
own choice of front and rear sights (e.g. Windham Weaponry SRC & Varmint
Exterminator models).
• Barrels on Windham Weaponry models are chrome lined 4150 chrome moly
vanadium 11595E steel or 416R grade stainless steel. They are 100% air gauged, bore
scoped, head spaced and buon rifled - right hand twist with 6 lands and grooves.
Refer to barrel markings for twist rate and caliber.
• Windham Weaponry models are supplied with 6 posion telescoping bustocks or
fixed style bustocks.
• Most forends are ribbed and vented to allow heat dissipaon. Carbines feature M4
double heat shield design forends.
• All models feature vercal pistol grips and detachable magazines. Standard magazine
capacity is 30 rounds (depending on State regulaons), but all AR-15/M-16 type
magazines of capacies from 5 to 40 rounds as well as c-drum magazines will fit and
funcon in Windham Weaponry models.

must clear the cutouts in
the aluminum upper
receiver for removal and
reinseron.
Slide charging
handle straight
in or out of the

upper receiver.
NOTE: On the Carbon Fiber lower receivers, the
Takedown Pin is within molded recesses, and will
require the Safety Tool, a punch or some similar
tool to reach it and push it in.
NOTE: On the Carbon Fiber upper receivers, the Charging
Handle simply slides straight in or out of the upper
receiver. There are no “cutouts” in the charging handle
track as in the aluminum receiver (see Fig. 9A)
CAUTION: Because of this, if you hold the Carbon Fiber
receiver vercally (with barrel up), the Charging Handle
and Bolt Carrier can fall out and possibly be damaged.

8. Run a cleaning patch with oil through the barrel. Always pull your
cleaning rod from chamber to muzzle (Fig. 10).
9. Run a dry patch through the barrel (again, always from chamber to
muzzle).
10. Visually inspect the barrel to make sure it is free of any debris or
obstrucons.
11. To reassemble your rifle, follow the preceding steps (1 thru 7) in
reverse order.
NOTE: When installing the charging
handle, remember that the tabs on the
side of the handle need to drop into
corresponding cutouts in the channel
within the upper receiver (Fig. 11).
NOTE: When installing the bolt
carrier assembly, the bolt must be
pulled all the way forward before
being inserted in the upper receiver
(Fig. 12).
The bolt carrier can then be
reinserted in the upper receiver. The
gas key must fit into the channel in the
charging handle. Then, both charging
handle and carrier can slide into
receiver (Fig. 13).
With the upper receiver
reassembled, it can then be joined to
the lower receiver.
NOTE: When pivong the rifle
closed, the hammer should be in the
cocked (down) posion (Fig. 14). The
safety can then be moved to the SAFE
posion.
12. Pull the charging handle to the
rear and insert the chamber plug/tool
into the chamber. Then ease the
charging handle and bolt carrier
forward, and latch the charging handle
in place.

RANGE SAFETY CHECKS - BEFORE YOU FIRE!
1. USE ONLY QUALITY AMMUNITION THAT IS APPROPRIATE TO THE CALIBER MARKED ON THE
BARREL OF YOUR RIFLE. Brass cased ammunion is recommended.
CAUTION! DO NOT USE AMMUNITION THAT IS DENTED, SCRATCHED,
CORRODED, OR DAMAGED.
2. Insert a cartridge between the feed lips of the magazine with the bullet p forward. Push the
cartridge down unl it is held by the magazine feed lips (as shown Arrow A - Fig. 15).
3. Then slide the cartridge backward to seat it against the inside back of the magazine (Arrow B -
Fig. 15). Place the next cartridge on top of the previous one and repeat steps 2 & 3 unl desired
number of cartridges are loaded into the magazine (Fig. 16).
CAUTION! DO NOT LOAD LIVE AMMUNITION INTO YOUR MAGAZINE UNTIL YOU
ARE READY TO SHOOT.
NOTE: AR15/M16 type magazines will hold various capacies of ammunion - anywhere
from 5 to 100 cartridges - but all funcon in the same manner. Do not try to force more cartridges
into a magazine than it was designed to hold.
Note also that .223/5.56 magazines can also be used with .300 Blackout ammunion in rifles
chambered & barreled for that caliber. Always be sure the ammunion you use matches the caliber
marking on the barrel of your rifle.
ALWAYS ASSUME THE RIFLE YOU ARE HANDLING IS LOADED, AND POINT IT IN A SAFE
DIRECTION! WHEN PERFORMING THIS SAFETY CHECK, MAKE SURE THERE IS NO MAGAZINE IN
THE RIFLE.
SAFETY SELECTOR FUNCTION CHECK: Perform this safety funcon check to ensure that the safety
selector lever works properly.

Insert a loaded magazine into the magazine well unl the magazine catch engages and holds the
magazine. Slap up on the boom of the magazine to ensure it is seated correctly.
Pull charging handle fully to the rear (Fig. 21).
Release charging handle. Never “ride” the charging handle forward. The charging handle and bolt
assembly should slide forward from the pressure of the acon spring to chamber a round (Fig. 22).
Then tap the forward assist to ensure bolt is fully forward and locked (Fig. 23). Now move the
safety selector to the SAFE posion.
1. Aim at your target.
2. Move safety selector lever from SAFE to FIRE (Fig. 24).
3. Squeeze the trigger – release trigger pressure.
4. The rifle will eject the spent cartridge and chamber another in
preparaon for the next shot. This is called firing in “semi-automac mode”.
One round will be fired with each pull of the trigger, and the rifle will
automacally reload, unl the magazine is empty.
NOTE: Aer the last round is fired, the bolt carrier will lock in the rear posion. You can then push
the magazine release buon to drop out the empty magazine*, insert a fresh magazine, release the
bolt catch, and a new round will automacally be chambered in preparaon for the next shot.
If you stop firing the rifle before the magazine is empty:
1. Move safety to SAFE posion.
2. Remove magazine.
3. Lock bolt to the rear (to remove live round from the chamber).
4. Visually inspect the chamber to ensure that it is empty.
*For California approved models, use the chamber plug/tool to
depress the bullet buon to drop out the empty magazine (Fig. 25).

*If a bullet is stuck in the barrel, do not aempt to remove it. Contact Windham Weaponry for
Technical Support. Call: 1-855-808-1888
WARNING! If your rifle stops firing with a live round in the chamber of a hot barrel,
remove the round FAST! However, if you cannot remove it within 10 seconds, remove the
magazine and wait 15 minutes with the rifle poinng in a safe direcon! This way you won’t
get hurt by a possible round “cooking off” (meaning a round may detonate unexpectedly
from being exposed to the heat of the rifle’s firing chamber). Always be sure to keep your face away
from the ejecon port while clearing a hot chamber.
If your rifle sll fails to fire, check the troubleshoong secon of this manual.
CHROME LINED BARRELS
First run a dry patch down the bore to remove any oil le in the barrel as it came from the factory.
Barrel Break-in Procedures for Chrome Lined Barrels (regardless of caliber) require firing
approximately 100 rounds of good quality brass cased ammunion. Then clean the barrel thoroughly
according to the instrucons in this Operators Manual (Page 22), and your rifle will be ready for the
range or the hunt.
STAINLESS STEEL BARRELS
First run a dry patch down the bore to remove any oil le in the barrel as it came from the factory.
Fire one shot, then clean the barrel - repeat this one shot & clean process 5 mes. Fire three shots,
then clean the barrel. Fire five shots, then clean the barrel, and your stainless steel barrel will be well
broken in.
IF YOU HEAR A NOTICEABLE DIFFERENCE IN SOUND OR RECOIL DURING
FIRING, STOP FIRING! EITHER CONDITION COULD INDICATE AN
INCOMPLETE POWDER BURN AND/OR A STUCK BULLET IN THE BORE.*

Once the rifle is zeroed, the rear sight is
adjustable for elevaon when firing at distances of
300 - 600 meters (A4 sights) or 300 - 800 meters (A2
sights).

*Sighng Data from Army Marksmanship manual.
25 meters = 27 yards + 1 . (82 .) 100 meters = 109 yards + 1 . (328 .)
NOTE: On Carbon Fiber Upper Receivers, the Picanny rail is .040” higher than on aluminum receivers. It
may therefore be necessary to use a .040” taller front sight post if raising your exisng front sight post
doesn’t allow sighng in accuracy. Taller front sight posts are available on our website:
www.windhamweaponry.com (Part number: 9349056-MOD)
*AII the above values have been rounded off. To
remember your correct zero windage, note locaon
of windage scale and windage knob pointer (heavy
mark on outside of knob). Once you have established
your correct zero windage leave your windage scale
and windage knob pointer on these sengs at all
mes.

THE DUAL APERTURE REAR SIGHT
25 METER ZEROING PROCEDURES
ADJUSTABLE FOR ELEVATION & WINDAGE
By following the steps below and establishing a zero at 25 meters, your rifle sights will be set with a
300-meter balesight (these instrucons apply to a 16” Bbl. Carbine).
1. Do not move front sight post at this me. It was set at the factory and should be very close to
your zero.
2. The unmarked (smaller) aperture should be flipped up - see figure 29 above.
3. Center the rear sight aperture by turning the windage knob le or right (this is called
“mechanical zero windage”.
4. Rotate elevaon knob in the down
direcon (counter-clockwise - Fig. 30) to
boom out the rear sight. This is called
“mechanical zero elevaon” for the rear sight
on all Carbines, and applies whether you have
the A2 Sight (Fixed Carry Handle Carbine) or
the A4 Sight (Removable Carry Handle).
On rifles with a rifle length sighng radius like our 20 inch Gov’t Model, you move the rear
elevaon up one click from the boomed posion for A2 Sights and two clicks to the “Z” mark on the
A4 Carry Handle Sights.
From this point on, the rear sight elevaon knob should not be moved. Any changes in elevaon
required in the following zeroing steps are made to the front sight post only.
5. Carefully aim and fire at the center of the target bulls-eye.
6. If your shot group is not in the center of the bulls-eye, calculate the required “clicks” necessary
to move your next shot group into the bulls-eye using the elevaon and windage values in the
“Understanding Your Sight Adjustment” secon on the previous page. Remember that any changes in
elevaon are made by moving the front sight post only.
A. In order to raise your next shot group, rotate the front sight post clockwise. In order to lower
your next shot group, rotate the front sight post counterclockwise.
B. Changes in windage are made with the windage knob. To move the shot group to the le, turn
the windage knob counterclockwise. To move the shot group to the right, turn the windage knob
clockwise.
Short Range (0-200 meters)
Normal Range - A2 Sights: 300-800 meters
A4 Sights: 300-600 meters
SHORT RANGE - The “02” (larger) aperture is
used for 0-200 meters range. As shown below,
the sight is set for 0 - 200 meters. This larger
aperture is only used when the rear sight is all
the way down. In other words, the 300-meter
mark is aligned with the mark on the le side of
the receiver (Fig. 28).
NORMAL RANGE - The aperture is
unmarked and used for most firing situaons. It
is used in conjuncon with the elevaon knob
for 300, 400, 500, 600, 700, and 800 meter
targets with A2 sights (Fig. 29).
With A4 carry handle sights, ranges are 300,
400, 500, 600 meters.

25 METER ZEROING PROCEDURES (connued)
THE RIFLE IS NOW SAFE TO TRANSPORT
FROM THE RANGE.
7. Carefully aim and fire another group at the center of the target bulls-eye.
8. Repeat steps 5 and 6, if required.
9. When your group is on target, your sight is now “calibrated” for balesight zero. If your rifle has
a rifle length sight radius, move the elevaon knob back down to the 6/3 posion for A4 removable
carry handles, or 8/3 for A2s fixed carry handles. The range scale’s 300-meter mark should now be
aligned with the corresponding index above the elevaon wheel.
1. Clear the rifle to ensure the chamber is
empty (Fig. 31).
2. Place safety in the safe posion.
3. Pull the charging handle to the rear and
insert the chamber plug/tool into the chamber.
Then ease the charging handle and bolt forward
and latch in place (Fig. 32).

RIFLE DISASSEMBLY, CLEANING & MAINTENANCE
ALWAYS FOLLOW THE RULES OF SAFE GUN HANDLING!
ALWAYS ASSUME THE GUN YOU ARE HANDLING
IS LOADED.
POINT THE RIFLE IN A SAFE DIRECTION!
Place the safety selector lever on SAFE (Fig.33).
NOTE: If the rifle is not cocked, the safety selector lever
cannot be pointed toward SAFE.
A NOTE REGARDING CARBON FIBER RECEIVERS:
Because of very minor dimensional differences, you cannot assemble
an Aluminum Upper Receiver Assembly onto a Carbon Fiber Lower
Receiver Assembly. Use of force to assemble these components will cause damage. Conversely, do not
aempt to aach a Carbon Fiber Upper Receiver Assembly onto an Aluminum Lower Receiver Assembly.
There are also minor differences between the Carbon Fiber model’s barrel nut and that of Aluminum
receivered models. Barrel Nut threading is different on Carbon Fiber models, and we also use Locte on
Carbon Fiber Barrel Nuts, so aempng to remove a Carbon Fiber Barrel Nut can cause damage to the
Carbon Fiber Upper Receiver, and may void your warranty. This Carbon Fiber Barrel Nut difference limits
the number of accessory forends that can be mounted to the Carbon Fiber rifle. Call Windham
Weaponry Technical Assistance if you have quesons on this.

1. To lock the bolt open, pull the charging handle rearward (A - Fig. 34). Press the boom of the
bolt catch and allow the bolt to move forward unl it engages the bolt catch (B - Fig. 34). Return the
charging handle to its forward posion.
If you haven’t done so before, place the safety selector lever on SAFE
.
2. Remove the chamber plug/tool (Fig. 35).
Look into the upper receiver and firing
chamber to ensure there is no ammunion in
the rifle (Fig. 36).
NOTE: Be sure a magazine is not inserted
in the rifle.
3. Once you are sure the firing chamber is
empty, and the safety selector lever is on
SAFE, you can press the upper poron of the
bolt catch, or pull the charging handle all the
way to the rear and release to allow the bolt
to move forward (Fig 37).

4. Using your chamber plug/tool (or a punch)
push the takedown pin in as far as it will go.
Then pull on the head of the pin (from the right
side of the rifle) unl it stops (Fig. 38).
5. Push the pivot pin in as far as it will go (Fig.
39) - then separate the upper and lower
receivers (Fig. 40).
REMEMBER: Carbon Fiber lower receivers will
require a tool to reach the Takedown Pin.

13. Once the bolt carrier has been disassembled...
A. Clean the gas key on top of the bolt carrier with a pipe cleaner or Q-p (Fig. 49). Lightly oil the
gas key (Fig. 50). Clean carbon and powder residue from vent holes and outer and inner surfaces of
the bolt carrier. Use a bore brush - wet with CLP - to clean carbon and powder residue from around
the gas tube.
B. Clean and inspect the bolt, cam pin, firing pin and firing pin retaining pin thoroughly. Clean the
bolt locking lugs, bolt rings, firing pin, firing pin hole and cam pin (Fig. 51).

14. Remove extractor pin by pushing it out with the p of the firing pin or a punch. Take care not to
damage the firing pin, or lose the extractor pin (Fig. 52).
15. Remove the extractor with its spring, insert and o-ring (Fig. 53).
CAUTION: It is unlikely, but if the extractor spring should pop out of its recess, reset the spring by
pressing it back in its recess with a punch as shown in Fig. 55 (on next page).
Fig. 57
Fig. 55
17. Reinsert extractor in bolt (Fig. 56). Press extractor down to reinsert extractor pin (Fig. 57).
16. Check the extractor, extractor spring, insert and o-ring. If the extractor is chipped, or if the lip
that engages the cartridge rim has broken edges, the extractor should be replaced. Check that the
rubber insert is inside the extractor spring. Clean off any carbon buildup or powder residue (Fig. 54).
Use CLP to clean any carbon buildup or powder residue in the extractor pocket/channel of the bolt.
Use a pipe cleaner and CLP to clean the firing pin channel of carbon buildup and powder residue.
NOTE*: Extractor assembly has a rubber insert within the spring. Be sure not to lose it. If the spring
comes loose, put the large end of spring in the extractor and seat it with a punch (Fig.55).

round, under the lip of the extractor. With a
rocking moon, press the case down against the
ejector. The ejector is spring loaded, so you will
feel some resistance. Press on the case unl it
stops against the bolt face. Rock the case back and
forth several mes to work the CLP lubricant into
the ejector and its spring. Relubricate the ejector,
and repeat the rocking moon several mes. Once

CAUTION: The bolt should not have any cracks or fractures - especially in the cam pin hole area.
The bolt face should not have any ping - especially around the firing pin hole. If this ping is found,
the bolt must be replaced.
• The cam pin should not be cracked or excessively worn. If so, replace it.
NOTE: In as lile as 100 rounds, normal wear on a Cam Pin can show an indented paern where
the Bolt and Cam Pin interact. This is not a crack, or a dangerous situaon. Real cracks in the Cam Pin
however, can cause a catastrophic failure.

WARNING: Regarding swapping bolts between rifles, while Windham Weaponry rifles
and bolts are machined with great care, and are interchangeable with other Windham
Weaponry bolts, we do not recommend exchanging bolts - parcularly those from other
manufacturers, without first checking for proper headspacing with a Field Gauge or
Go/No-Go Gauge for .223 Rem./5.56mm NATO.

INSERT CAM PIN:
Insert cam pin into carrier and hole in
bolt body (Fig. 63).
NOTE: The cam pin should only fit
into the bolt from one side. If it doesn’t
slip in easily, turn bolt body 180° within
the carrier and try again. Aer cam pin
is inserted, turn it 90°. This allows for
the inseron of the firing pin.
INSERT FIRING PIN:
Drop firing pin into back end of bolt
carrier (Fig. 64) and seat by pushing in
all the way (Fig. 65).
INSERT FIRING PIN RETAINING PIN:
Insert firing pin retaining pin into the
firing pin retaining pin hole in the side of
the carrier as shown (Fig.66).
NOTE: In the cutaway drawing, the
firing pin retaining pin sits behind the
large shoulder of the firing pin. The test
for correct posioning is that the firing
pin should not fall out when bolt carrier
group is turned upside down.
Now that the bolt carrier is fully
reassembled, move the bolt in and out
of the carrier to ensure that the cam pin retains the
bolt in the carrier and that the cam pin moves freely
in the cam pin track.
Tap the rear of the bolt carrier on a solid surface to
ensure that the firing pin and its retaining pin is
installed properly.
Now lightly lubricate the bolt carrier assembly and
charging handle assembly.

RIFLE DISASSEMBLY, CLEANING & MAINTENANCE (Connued)
These steps have been adapted from the US Gov’t. Manual and involve the
use of the standard issue M16 cleaning kit. You can achieve comparable results
with any high quality rifle cleaning kit. Be sure your kit includes a quality
cleaning rod; patch holder; coon flannel bore patches; pipe cleaners; a small
toothbrush; brass wire bristle bore and chamber brushes; and a
Cleaner/Lubricant/Preservave (CLP). If you use an ammonia based solvent
while cleaning a chrome lined barrel, do not let it sit in the bore for more than
10 minutes. This will cause premature deterioraon of the chrome lining. The
toothbrush is for cleaning parts and dislodging dirt. Pipe cleaners or Q-ps are
for cleaning the gas key, gas tube and other hard to reach areas.
CLEANING THE BORE:
ALWAYS CLEAN FROM CHAMBER TOWARDS THE MUZZLE AND ALWAYS
PULL THE BORE BRUSH THROUGH THE BORE
The bore of your Windham Weaponry rifle has lands and grooves called
rifling. Rifling makes the bullet spin very fast as it moves down the bore and
down range. Because it twists so quickly, it is difficult to push a new, sff bore
brush through the bore. You will find it much easier to pull your bore brush
through the bore. Also, because the brush will clean beer if the bristles follow
the grooves (called tracking), you want the bore brush to be allowed to turn as
you pull it through.
1. Swab out the bore with a patch moistened with CLP.
2. If using a mul-piece military cleaning rod, aach three rod secons
together but leave each one about two turns short of being ght (Fig. 67).
3. Aach the bore brush. The rod and bore brush will twist as you pull it
through - following the path of the rifling. NEVER reverse the direcon of the
bore brush while it is in the bore.
4. Point the muzzle down. Hold the upper receiver in one hand while
inserng the end of the rod without the brush into the firing chamber. Let the
rod fall straight through the bore. About 2-3 inches will be scking out of the
muzzle at this point.
5. Aach the handle secon of the cleaning rod to the end of the rod
scking out of the muzzle (Fig. 68).
6. Pull the brush through the bore and out the muzzle.
7. Aer one pull, take off the handle secon and repeat the process.
8. Send a patch through the bore once in a while to help clean out the crud
that the brush is geng loose. You can use the same technique as described
above to save me. Just replace the bore brush with the rod p (patch holder)
and a wet patch. Drop it through. You won’t need to aach the handle to pull
only a patch through. If you leave the rods loose again, the patch will “track” in
the rifling as before. Remember - always have the bore wet with cleaner before
trying to pull a brush through.

CLEANING THE UPPER RECEIVER
Fig. 70
Fig. 69
1. Using CLP, clean all areas of the upper receiver
(inside and out) to remove powder fouling, corrosion
and dirt.
NOTE: Never use a wire brush or any type of
abrasive to clean the aluminum upper receiver - you
could scratch and damage the anodized finish. A
toothbrush can be effecve to loosen dirt buildup,
and won’t scratch the receiver.
2. Clean the chamber by moistening the larger
chamber brush with CLP, and use plunge strokes and
clockwise rotaons (Fig. 69).
NOTE: Do not push the larger poron of the
chamber brush into the bore.
3. Swab out the chamber and bore to remove
contaminated CLP, carbon buildup and powder fouling. Wipe all components clean and dry, and
inspect for any excessive wear, corrosion or mechanical damage. Replace any worn or defecve parts
before your next shoong session. Contact Windham Weaponry toll free at 1-855-808-1888 for parts

RIFLE DISASSEMBLY, CLEANING & MAINTENANCE (Connued)
1. UPPER RECEIVER: Lightly lubricate the inside of upper receiver, the bore and chamber (using
the cleaning rod and a patch), the outer surfaces of the barrel and front sight, and surfaces under the
handguards. Take special care to clean and lubricate the locking lugs just outside the firing chamber.
The forward assist should also be lightly lubed inside the
receiver and checked for funcon (Fig. 72).
2. FRONT SIGHT DETENT: Depress the detent, and apply
two or three drops of CLP to it. Depress the detent several
mes to work the lubricant down into the spring (Fig. 73).

1. To remove the handguards, pull delta ring towards you, gently tap handguards on the edge of
your work surface on the seam where the handguards come together (Fig. 70). The handguards will
separate and can now be removed (Fig.71).
NOTE: On VEX & .308 Hunter Models with Laminate Wooden Forends, the Handguards are split
vercally rather than horizontally. Removal procedure is similar to that shown below.
If your rifle has a free floang handguard, it is not recommended to remove it for barrel cleaning.
You can clean/lubricate the barrel through venng slots or from the open end with a cleaning rod and
a wet patch.

NOTE: Make a note of how far you
move the sights so they can be returned
to their original posion aer
compleng this lubricaon procedure
(Fig. 74).
MOVING PARTS: Use one or two
drops of CLP. Rotate these parts to
ensure lubricant is spread evenly above
and below the elevaon knob /
elevaon screw sha / windage knob
(maximum five clicks le or right) /
windage screw / detent holes.
ELEVATION SCREW SHAFT: Remove
A4 carry handle to lubricate the
elevaon screw (or, if you have an A2
fixed carry handle upper receiver, look
inside the upper). Put two or three
drops of CLP on boom of elevaon screw sha and in elevaon detent spring hole. Rotate the
elevaon dial back and forth a few mes while keeping upper receiver upside down.
AFTER LUBING REAR SIGHT: Reset your correct zero windage and your balesight zero. Refer to
the secon within this manual about seng balesight zero. Noce the rear sight comes down when
the “6/3 or 8/3” is aligned with the mark on the le side of the receiver. You will feel a “click" when
the “6/3 or 8/3” first lines up with the mark. Carry your rifle with the “6/3 or 8/3” aligned with the
mark. Keep the sight on 300 meters to keep dirt and water out of sight mechanism and protect the
sight from damage.
IF YOU GET THE REAR SIGHT WET: Clean it as soon as possible to avoid the onset of rust and
corrosion.
REINSTALLING THE HANDGUARDS
1. Insert the first half of the handguard into the handguard cap.
Then pull the delta ring back and insert rear part of the handguard
onto the delta ring as shown (Fig. 75).
2. Now insert the second half of the handguard into the
handguard cap and pull back the delta ring and slide the rear of the
handguard onto the delta ring as shown (Fig. 76).
Fig. 75
Fig. 76
Fig. 77
3. Then squeeze the rear of the handguard halves as shown unl
they snap into the delta ring. (Fig.77).
NOTE: The two halves of standard issue rifle and carbine length
handguards are idencal, and so can be installed either on top or
boom. Remember that Wood Forend Sets are split vercally, not
horzontally, and are mirror image parts. When re-installing, posion
the cooling vents on the upper side of the barrel.

1. With the hammer cocked,
depress buffer retainer with chamber
plug tool or punch to release buffer
and spring (Fig. 80).
NOTE: Hammer must be cocked to
allow clearance for removal of buffer
and spring.
CAUTION: The buffer is under
tension from the acon spring.
2. Pull buffer and acon spring out
for cleaning (Fig. 81).
NOTE: Windham Weaponry does
not recommend any further
disassembly of rifle components or
subsystems. If you need further service
or parts, consult the factory or a
qualified gunsmith.
Fig. 80
Fig. 82
Fig. 81
1. INSTALL THE CHARGING HANDLE: Insert the
charging handle into the upper receiver and align
the tabs on the charging handle with the
corresponding slots in the upper receiver.
Then push the charging handle down into the
charging handle groove and slide it part way
forward (Fig. 78).
REMEMBER: On Carbon Fiber upper receivers,
the Charging Handle simply slides straight into the
receiver - there are no “cutouts” as in the
aluminum upper receiver.
2. INSTALL THE BOLT CARRIER: Pull
the bolt to the “out” posion in the
carrier. As you install the bolt carrier,
align the gas key with the channel in the
charging handle. Then push the bolt
carrier and charging handle all the way
forward unl the bolt carrier is flush
with the back of the upper receiver and
the charging handle latches in place
(Fig. 79).
Pg. 26
LOWER RECEIVER GROUP: lightly lubricate inside the lower receiver extension (buffer tube), as
well as the buffer and acon spring.
Generously lubricate the takedown and pivot pins and their detents, all moving parts inside the
lower receiver and their pins.

NOTE: Some Windham Weaponry rifles sold as “Ban Compliant Models” in the States of New York,
Conneccut, Massachuses, and New Jersey have permanently extended (fixed length) telestocks.
The length of pull cannot be changed as the receiver extension is longer than on an adjustable
telestock. See the differences noted in Fig. 84A below. The Ban Compliant stock will not have the
machined adjustment recesses found on the adjustable telestock.
DO NOT aempt to adjust the length of, or disassemble, the Ban Compliant stock as you will
damage it.

1. Using CLP, or a quality gun cleaner, clean all areas on the lower receiver of any powder fouling,
corrosion and dirt. Use of a toothbrush will avoid scratching the finish - NEVER use a wire brush.
2. Clean any dirt from the trigger mechanism. Carefully clean the magazine release buon and the
cavity for the magazine catch on the le side of the receiver. Inspect and clean the bolt catch
mechanism and lower receivers takedown and pivot pins. Clean the buffer, acon spring, and inside
the lower receiver extension (also called the buffer tube). A cloth aached to the cleaning rod and
patch holder can be used to wipe inside the buffer tube. Note that Windham Weaponry uses
Commercial Specificaon Buffer Tubes on Telestocked models. Cleaning procedures are similar for Mil.
Spec. & A2 (solid stock) models.
3. If the rifle has been used in dirty or muddy condions, clean out the vent hole in the telestock
receiver extension (or the vent screw in the A2 solid bustock) with a pipe cleaner or piece of wire to
ensure that the vent hole is clear.
4. Clean telestock or bustock as necessary. The telestock latch can be pulled down to remove the
stock (as shown in Figures 83 & 84). Clean the 6 posion lock holes, and lightly lube the receiver
extension and latch mechanism to ensure proper telescoping acon. A2 solid bustocks may require
cleaning and lubricaon of storage compartment door latch and hinge.
Pg. 27
To clean and lubricate the magazine, use a cleaning rod with a cleaning patch aached to clean and
lubricate the inside of the magazine body.
Lightly lubricate the spring, and reassemble the magazine in the reverse order of the steps
above.
CAUTION: Make sure the magazine is unloaded before disassembly.
To disassemble a magazine for cleaning or lubricaon, follow these steps:
1. Pry up the back edge of the baseplate with a punch to release the base catch tabs from the
magazine body (Fig. 87).
2. Slide the baseplate clear of the body (Fig. 88).
CAUTION: The magazine spring will be under tension and may pop out.
3. The magazine spring may get caught on the tabs that hold the baseplate in place. As you pull the
spring out of the magazine body, move the spring back and forth so that it will not get hung up on the
tabs. Figure 89 shows disassembled magazine components.
NOTE: Do not remove the follower from spring.

JOIN THE UPPER & LOWER RECEIVERS:
1. Posion upper receiver so that receiver
pivot pin can slide into forward lug of upper
receiver.
2. Push pivot pin in, close upper receiver
completely onto lower (with hammer cocked).
3. Push in rear takedown pin (Fig. 86).
A NOTE REGARDING CARBON FIBER RECEIVERS:
Because of very minor dimensional differences,
you cannot assemble an Aluminum Upper Receiver
Assembly onto a Carbon Fiber Lower Receiver
Assembly. Use of force to assemble these
components will cause damage. Conversely, do not
aempt to aach a Carbon Fiber Upper Receiver Assembly onto an Aluminum Lower Receiver Assembly.
There are also minor differences between the Carbon Fiber model’s barrel nut and that of Aluminum
receivered models. Barrel Nut threading is different on Carbon Fiber models, and we also use Locte on
Carbon Fiber Barrel Nuts, so aempng to remove a Carbon Fiber Barrel Nut can cause damage to the
Carbon Fiber Upper Receiver, and may void your warranty. This Carbon Fiber Barrel Nut difference limits
the number of accessory forends that can be mounted to the Carbon Fiber rifle. Call Windham
Weaponry Technical Assistance if you have quesons on this.
LOWER RECEIVER REASSEMBLY:
Insert acon spring and buffer. You may have
to “wiggle” the acon spring past the buffer
detent as you insert it (Fig. 85).

ADDENDUM: INFORMATION ON .308 CALIBER RIFLES
What’s Different about the .308 Caliber Rifles
The first, and most important point regarding your Windham Weaponry .308 Caliber Rifle is that you
should follow all the same maintenance procedures shown elsewhere in this Windham Weaponry
Operang and Safety Manual. The .308 Caliber Rifle funcons and maintenance procedures are all the
same as our .223/5.56mm caliber rifles, and should be followed as shown in the various secons of this
Manual.
Below, you’ll find the minor differences that set the .308 Caliber Rifles apart from our .223/5.56mm
models. If you have any quesons regarding maintenance, services or you need parts for your .308
Rifle, please call Toll-Free: 1-855-808 1888, and we will be happy to help.
ALWAYS USE THE CORRECT AMMUNITION FOR YOUR PARTICULAR FIREARM!
Windham Weaponry Barrels have permanent markings that indicate the proper caliber and chamber-
ing. Always refer to the BARREL markings when selecng ammunion for your firearm. Use only factory
ammunion manufactured to U.S. industry standards. Failure to use the proper caliber ammunion can
damage your firearm, and may cause injury or death.
• Buffer & Acon Spring: These parts are specific to the .308. The Buffer is shorter, and the Acon
Spring has a few less coils than an AR, but removal and maintenance are the same. The Telescoping
Bustock is the same as an AR, and the Buffer and Acon Spring funcon in exactly the same way.
• Trigger Guard: On the .308 SRC, the Trigger Guard is an integral machined aluminum part of the
Lower Receiver, and does not swivel down from the Lower Receiver.
• Receivers: On the .308, the receivers are CNC machined
from 7075 T6 Aircra Aluminum Forgings large enough to
contain the caliber specific - and unique - bolt carrier and bolt.
The lower receiver has machined sockets each side behind the
pistol grip that are intended for Quick Detach sling swivels
similar to that supplied on the barrel’s gas block. This feature
offers mulple sling aachment points.
• Bolt & Bolt Carrier: The bolt carrier, bolt assembly, cam
pin, and firing pin are unique, and caliber specific to the .308.
Other internal parts however, such as Gas Key, Gas Key Screws,
and Firing Pin Retaining Pin, are standard “AR” parts.
.308 Caliber SRC - Model R16FTT-308
.308 Caliber Timbertec Camo SRC
Model R16FTT-308-C3
Just a few of the various Windham Weaponry
.308 Caliber models are shown above.
.308 Hunter - Model R18FFTWS-2-308
• Caliber: This rifle is designed - and chambered for - the .308 Winchester round, but it is
important to note that it will also chamber and safely fire the common 7.62 x 51mm round. The
Magazine supplied with this rifle works equally well with either cartridge.
NOTE: There is no Extractor Spring Insert like .223 rifles in the
.308, and in disassembling the .308 Carrier, the Cam Pin pulls
straight out rather than rotang 1/4 turn as on .223 assemblies.
Pg. 29
ADDENDUM: INFORMATION ON .308 CALIBER RIFLES
• A CAUTION ABOUT PARTS INTERCHANGEABILITY: The Windham Weaponry .308 SRC has been
developed as a unique product offering, and its parts and components are not intended, or designed,
to fit any other manufacturers .308 rifles regardless of any apparent similarity.
Owners should never aempt to use other manufacturers parts on or in the Windham Weaponry
.308 SRC. To do so could cause damage to your rifle, possibly inflict injury on the shooter or those in
the vicinity of the shooter, and could void your warranty.
If you have any quesons about your Windham Weaponry .308 SRC, or any of its parts or
components, or quesons about adding any aermarket accessories to the rifle, please call the
Windham Weaponry Customer Service / Technical Line - Toll Free (1-855-808-1888) between 8:30
AM and 5:00 PM (Eastern Standard Time) Monday through Friday. Or, quesons can be E-mailed to:
info@windhamweaponry.com and we will respond promptly.
• Pivot & Takedown Pins: The Pivot Pin is longer than
an AR type, but held within the Lower with standard AR
Detent and Spring. The Takedown Pin is an AR part, and is
retained within the Lower by a standard AR Detent and
Spring, but is held in place by the Pistol Grip just like the
Safety parts rather than from the rear of the Lower like on
an AR.
• Hammer & Trigger: The Hammer, Trigger, their
Springs and Pins, are all AR type parts, and funcon just as
in an AR-15 rifle.
• Hogue Beavertail Pistol Grip: This is a quality
aermarket part that while not specific to only the
.308 SRC, is nevertheless very well suited for it. It fits
larger hands a bit beer, and its “beavertail
backstrap” snugly fits the Lower Receiver and
provides beer padding for the webbing between
the thumb and index finger with the slightly heavier
recoil of the .308 cartridge.
• Bolt Catch Screw: The aachment of the Bolt
Catch on the .308 Lower Receiver is different than
on AR lowers. A special Allen head pin/screw (with 1/16” socket) is used to hold the Bolt Catch in
place. The funcon and operaon of the Bolt Catch are idencal to the AR type rifle.
• Ejecon Port Cover & Ejecon Port Cover Rod: The
Ejecon Port Cover is larger than on an AR in accordance with
the larger .308 cartridges, and the Ejecon Port Cover Rod is
not retained with a C-clip as on an AR, but rather fits in a blind
hole so it won’t slide out to the rear. Forward movement of
the rod is stopped by the Barrel Nut.
BARREL: Windham Weaponry .308 barrels can range
from 16.5” to 20“ and are turned in Medium Profile and
Fluted versions. They all are Chrome Lined in the Bore &
Chamber, and machined from Chrome Moly Vanadium 11595E Steel. They are generally fied with an
A2 Type Flash Suppressor specific to the .308 caliber (threaded 5/8ths x 24 tpi), but may also have a
plain crowned muzzle. Rifling for .308 models is 1 turn in 10” - Right Hand Twist - 6 Lands & Grooves
The break-in procedure for this Chrome Lined Barrel is similar to the AR type rifles. We recommend
breaking the rifle in with any good quality brass cased ammunion - approximately 100 rounds. Then
clean the barrel thoroughly, and its ready for the range or the hunt.
Pg. 30
ADDENDUM: INFORMATION ON .308 CALIBER RIFLES
• .308 Gas Block: While idencal in funcon to the units
found on .223 rifles , this gas block has been machined to
receive the Quick Detach Push Buon Sling Swivel shown
here to offer rapid adjustment of sling posions, and ease in
stripping down the rifle for cleaning or maintenance
operaons. The Picanny Rail on the Gas Block is on the
same plane as the Upper Receiver for opmum sight
funcon.

or Tech Support Line Toll Free any me between 8:30 AM
and 5:00 PM E.S.T.: 1-855-808-1888
• Charging Handle: Longer, and specific to the .308, the Charging Handle is machined from 7075 T6
aluminum like its AR counterpart and the Latch, Latch Spring and Spring Pin are also standard AR parts.

• Caliber: This rifle is designed and chambered for the 7.62 x 39mm cartridge. This is the world
famous ammunion used most commonly in the Russian
designed “AK47”. We recommend using brass cased
ammunion and, although it may seem obvious, DO NOT
aempt to fire .223 Rem / 5.56mm ammunion in this rifle.
• Bolt: Due to the larger case diameter, the Bolt and
Extractor are unique - and caliber specific - to the Windham
Weaponry 7.62 x 39mm SRC. This Bolt is idenfied by the 3
rings machined into the body behind the lugs. Internal Bolt
Carrier parts however, such as Gas Key, Gas Key Screws, Firing
Pin and Firing Pin Retaining Pin, are standard “AR” parts.
Note: The 7.62 bolt does not use the extractor o-ring
commonly found in .223 rifles
• Receivers: On the 7.62 x 39mm SRC, the receivers are CNC
machined from 7075 T6 Aircra Aluminum Forgings - just the same as
our .223 Rem / 5.56mm rifles. They are however marked differently than
our .223 / 5.56mm lower receivers, and are stamped with “Mul” so
that we can ulize them for a variety of calibers. Internal Receiver parts
such as the Hammer, Trigger, their Springs and Pins, Buffer and Buffer
Spring, etc. are all AR type parts, and funcon just as in an AR-15 rifle.
• Barrel / Gas Block: The Barrel on the 7.62 x 39mm SRC is
chambered and bored for the 7.62 x 39mm cartridge. Rifling twist rate is
1 in 9.5”, right hand twist with 4 lands and grooves. The Gas Block/Front
Sight Base is funconally idencal to the units found on AR rifles and the

models. The .300 Blackout funcons and maintenance procedures are all the same and should be
followed as shown in the various secons of this Manual.
• Caliber: This rifle is designed and chambered for the .300 Blackout cartridge. It will also chamber
and fire the 7.62 x 35mm cartridge. We always recommend using brass cased ammunion. DO NOT
aempt to fire .223 Rem. / 5.56mm ammunion in this rifle.
Compare the two cartridges at right.
• Bolt: Because the case bases are the same dimensions,
the Bolt and Extractor are the same as our .223/5.56mm rifle.
• Receivers: On the .300 Blackout Rifle, the receivers are
CNC machined from 7075 T6 Aircra Aluminum Forgings -
just as our .223 Rem / 5.56mm rifles. The Upper Receiver is laser engraved .300 Blackout for safety
and quick idenficaon. The Lower Receiver is marked “Mul” so that we can ulize them for a
variety of calibers. Internal Receiver parts such as the Hammer, Trigger, their Springs and Pins, Buffer
and Buffer Spring, etc. are all AR type parts, and funcon just as in an AR-15 rifle.
• Barrel / Gas Block: The Barrel on .300 Blackout Rifle is machined in a medium profile, and
chambered and bored for the .300 Blackout cartridge. Rifling twist rate is 1 in 7”, right hand twist. The
Gas Block/Front Sight Base is funconally idencal to the units found on AR rifles.
