Fig.  12 – Gas 
Regulator Detent 
with no gas bleed port.  The gas bleed 
ports settings are located around the 
circumference of the gas regulator. The 
number visible on the top of the gas 
regulator indicates the setting.  See Fig. 
11.   The higher the number visible on top, 
the larger the volume of gas that is bled 
from the system and the lower amount of 
energy used to cycle the action.  
Conversely, the smaller the number on 
top, the smaller the volume of gas bled 
from the gas system and the higher the amount of energy available 
to cycle the action. 
 
To adjust the gas regulator, use the tip of a round to depress the gas 
regulator’s detent while turning the regulator to the desired setting. 
Fig. 12 shows the position of the detent. 
 
To get the gas regulator adjusted for any given ammunition or 
conditions, set the gas regulator so that the empty cases are 
consistently thrown approximately 5 to 7 feet from the rifle.  This 
should ensure reliable functioning. 
 
If the empty cartridge cases are not fully ejected from the receiver or 
are not ejected far enough from the firearm, it means that more gas 
is needed to cycle the action far enough to properly eject the empty 
cartridges.  Turn the gas regulator so that a smaller number is visible 
on top and try again.   
 
NOTE:  If the empty cartridge case is not ejected from the firearm, 
the empty cartridge may be forced back into the chamber.  Because 
empty cases swell slightly, it may be difficult to retract the charging 
handle.  If this is the case, strike the charging handle to the rear with 
you hand or other soft object.  This should break the empty case free 
of the chamber so it can be ejected.   Do not strike on the charging 
handle with hard objects to open the bolt. 
 
NOTE:   The gas adjustment regulator can be rotated in either 
direction.

Fig. 13 
Break In  
Your new rifle was manufactured to exacting tolerances.  Because of 
this, the action is somewhat tight and stiff to begin with.  Though 
your rifle was satisfactorily test fired at the factory, it was not 
broken in.  Proper break in of the rifle requires firing approximately 
100 to 200 rounds.  Without first breaking in the rifle, it may not 
feed properly from fully loaded 30 round magazines.  It is suggested 
that you: 1. 
Set the gas regulator so that the number 2 or 3 is visible on top.  
(If the firearm won’t cycle properly on these settings, try settings 
1 or 0). And;
 
2. 
Do not fully load the magazine you are using for the first 100 to 
200 rounds.
 
 SECTION X – UNLOADING 
 
WARNING!  EVEN THOUGH THE MAGAZINE 
HAS BEEN REMOVED, THE RIFLE MAY STILL 
BE LOADED.  THERE MAY STILL BE A ROUND 
IN THE CHAMBER WHICH COULD BE FIRED. 
ALWAYS KEEP THE RIFLE POINTED IN A SAFE 
DIRECTION WHILE UNLOADING THE FIREARM.  
ALWAYS VISUALLY INSPECT THE CHAMBER 
TO MAKE SURE NO ROUND IS PRESENT.
 
 
1.  Remove the magazine from the 
rifle by depressing the magazine 
release button with your right 
index finger (Fig. 13). Most 
magazines will drop from the 
rifle so be ready to catch them 
with your other hand. 
2.  While keeping the rifle pointed 
in a safe direction, move the 
safety lever to the fire position 
as indicated by the letter “F” and  
						

							 
23
 
Fig. 14 
retract the charging handle to its rearmost position   
3.  While holding the charging handle at its rearmost position, 
inspect the chamber to make certain that no round is present in 
the chamber (Fig.14).  
Pulling the charging handle 
to the rearmost position 
should eject any cartridge 
from the chamber, however, 
this is not always the case. 
4.  After visually inspecting the 
chamber and finding no 
round is present, release the 
cocking handle and move 
the safety selector to the 
safe position as indicated by 
the letter “S”. 
 
 SECTION XI – DISASSEMBLY 
 
WARNING!  MAKE SURE THE RIFLE HAS BEEN 
UNLOADED BEFORE ATTEMPTING TO 
DISASSEMBLE IT.   SEE SECTION X – 
UNLOADING. 
 
WARNING!  ADEQUATE EYE PROTECTION 
SHOULD ALWAYS BE WORN WHILE 
DISASSEMBLING ANY FIREARM AS SPRING 
LOADED PARTS MAY JUMP OUT AND MAY 
CAUSE PERMANENT VISION DAMAGE OR 
OTHER SERIOUS INJURY.
 
 
The M96 was designed to be disassembled and reassembled without 
the use of special tools.  Most of these procedures can be performed 
with the use of a .223 cartridge.   However the cartridge used as a 
tool may be damaged and should not be fired.

Barrel Removal 
 
WARNING!  DO NOT ATTEMPT TO TOUCH OR 
REMOVE THE BARREL FROM A RIFLE WHICH 
HAS JUST BEEN FIRED.  BARREL 
TEMPURATURES CAN REACH DANGEROUS 
LEVELS. MAKE SURE THE BARREL HAS 
COOLED COMPLETELY BEFORE ATTEMPTING 
TO TOUCH OR REMOVE IT.  FAILURE TO 
COMPLY WITH THIS WARNING MAY RESULT 
IN SERIOUS BURNS AND 
OTHER INJURIES.  1.  Set the butt of the rifle on a solid 
surface with the muzzle pointing 
upward in a safe direction.   
2.  Using the side of your right hand, push 
the charging handle down 
approximately three inches while 
simultaneously pushing in on the barrel 
release button with the thumb of the 
same hand (Fig. 15).  Push the button 
in as far as possible. 
3. While holding the charging handle 
down and the barrel release button in, 
use your left hand to grab the barrel by 
the gas block and twist the barrel 
slightly back and forth while pulling it 
out of the receiver (Fig. 16). 
 
NOTE:  If you find it difficult to push in 
the barrel release button while holding 
down the charging handle, you may first 
remove the bolt carrier assembly so that 
there is no need to push down on the 
charging handle while holding down the

barrel release button.   The instructions for removing the bolt carrier 
can also be found in this SECTION. 
 
NOTE:  If the barrel has been removed, do not pull back on the 
charging handle and release it.  Doing so may cause unnecessary 
wear on or damage to the parts. 
 Removal of Bolt Carrier Assembly  
1.  Move the safety lever to the fire position as indicated by the 
letter “F”.  Pull the cocking handle completely to the rear.  This 
action is to ensure the hammer is in the cocked position. (NOTE: 
The hammer must be in this position to remove the bolt carrier.)  
Release the charging handle allowing the bolt carrier to move 
forward.  Now move the safety 
lever to the safe position as 
indicated by the letter “S”. 
2.  Using the rim of a cartridge, push 
in the left side of the takedown 
pin as shown in Fig.17.  NOTE:  
If you use a punch, use it only to 
get the pin started.  Do    not force 
the pin all the way out.  It is meant 
to stay attached to the lower    
receiver. 
3.  Take hold of the right side of the 
takedown pin and pull it all the way to the right.  It will not 
come all the way out of the lower receiver. 
4.  Rotate the lower receiver down 
and away from the receiver, 
exposing the opening in the back 
of the receiver. 
5.  Using the tip of a bullet or similar 
object, depress the bolt carrier 
release button while 
simultaneously pulling it to the 
rear (Fig. 18). 
 
26
Fig. 19
 
6.  After you have pulled the bolt carrier free of the operating rod, 
tip up the muzzle end of the rifle so that the bolt carrier can slide 
out the back of the receiver.  Be ready to catch it!  
 
NOTE:  If the bolt carrier does not slide out the back of the receiver 
on its own, reach through the ejection port with a cleaning rod or 
similar object and lightly push the bolt carrier to the rear. 
  
NOTE:  Do not pull back on the charging handle and release it after 
the bolt carrier has been removed from the rifle. Doing so may 
damage the key on the operating rod. 
 
 Disassembly of  the Bolt Carrier Assembly  
1.  Use the tip of a cartridge to push 
out the pin which retains the back 
of the bolt carrier  as shown in 
Fig. 19. 
2.  Withdraw the back of the bolt 
carrier, firing pin, and firing pin 
return spring from the bolt carrier 
as shown in Fig. 20.  Pull the cam 
pin out of the bolt carrier  as

Disassembly of the Bolt  
1.  Depress the extractor very slightly 
straight into the bolt at its center 
(axis point) while simultaneously 
using the tip of a cartridge to push 
out the extractor’s axis pin (Fig. 
22). 
 
NOTE:  The extractor’s axis pin is 
stepped.  This requires the extractor to 
be slightly depressed in order to push 
out the axis pin.  The axis pin should come out easily if properly 
depressed.  Do not use a punch and hammer or similar instruments 
to try to remove this pin.  Doing so may damage the parts. 
 
2.  Pull the axis pin from the bolt. 
3.  Pull the extractor and its spring from the bolt.  Operating Rod and Gas Tube Removal  
The bolt carrier assembly and barrel must be removed before the 
operating rod and gas tube can be removed.   The operating rod 
should be removed before the gas tube is removed. 
 
To remove the operating rod: 
 
1.  Hold the receiver so the front 
faces you.  
2.  Push the operating rod into the 
receiver about 1” and turn the 
operating rod ¼ turn counter 
clockwise so that the key of the 
operating rod is sticking 
straight up.  If you look into 
the rear of the receiver after the 
¼ turn, the operating rod with 
its key should appear as in Fig. 
 
2823.  The parts have been enlarged in this picture. 
3.  Pull the operating rod from the rifle. 
  
NOTE:  The operating rod may be removed before the bolt carrier 
assembly is removed as long as the barrel has first been removed. 
 
To Remove the Gas Tube: 
 
The tas tube has one large and one small 
hole near its end.  First, insert the point of 
the cartridge or small bar through the two 
holes beginning with the larger hole.  
Using the cartridge, rotate the gas tube 
back and forth to loosen it.  See Figure 24.  
Next, extract the gas tube from the 
receiver. 
 
WARNING! USING A CARTRIDGE AS A TOOL MAY 
DAMAGE THE CARTRIDGE AND MAKE IT UNSAFE TO 
FIRE.  DISCARD THE CARTRIDGE AFTER USING IT AS A 
TOOL. 
 
 
Removal of Lower Receiver, Magazine Well, Rear 
Sight, Buttstock, Buttplate, and Handguard  
All the subassemblies mentioned in this section except the rear sight, 
are held to the receiver by interchangeable assembly pins.  The rear 
sight is held to the receiver by two special assembly pins of different 
lengths.  
   
NOTE:  When the rifle is new, it is more difficult to disassemble 
and reassemble.  If necessary use a brass punch and hammer to 
lightly tap out the assembly pins.

WARNING!  ADEQUATE EYE PROTECTION 
SHOULD ALWAYS BE WORN WHILE 
ASSEMBLING ANY FIREARM AS SPRING 
LOADED PARTS MAY JUMP FROM THE 
FIREARM AND MAY CAUSE PERMANENT 
VISION LOSS OR OTHER SERIOUS INJURY.  
Assemble the rifle components in the 
flowing order. 
 Gas Tube Installation  
1.  Attach the gas tube assembly to the 
receiver by sliding its narrow end into 
the gas tube guide of the receiver. 
2.  Insert the tip of a .223 cartridge 
through the two holes near the top of 
the gas tube as shown in Fig. 31.    
3.  Push the gas tube into the receiver 
keeping it straight.  The end of the gas 
tube needs to seat into a recess located 
about midpoint in the receiver (Fig. 
32). Continue to push the gas tube into 
the receiver until it is fully seated in the 
recess.   If necessary rotate the gas to 
back and forth as it is pressed into the 
receiver.   
4.  Once seated, rotate the gas tube so that its 
large holes are pointing down.  See Fig. 
33.   
NOTE:  If the barrel will not go far enough 
into the receiver to lock into place, the gas 
tube may not be seated properly.

Fig. 35 (Enlarged) 
Operating Rod Installation
 
1.  Hold the receiver with the front facing you.  Make sure the 
charging handle has been pushed completely forward. Push the 
operating rod into the gas tube as shown in Fig. 34.  The oprod 
key must be oriented straight toward the top of the receiver. 
2.  Guide the operating rod through its hole in the receiver.  This 
hole is located approximately midpoint inside the receiver.  
There is a slot on top of this hole 
through which the key of the 
operating rod must pass.   See Fig. 32 
for an enlarged picture of the hole 
and slot. 
3.  When you feel the washer of the 
operating rod hit inside the receiver, 
continue to push the operating rod 
into the receiver about one inch more 
and hold it there. 
4. Rotate the operating rod ¼ turn 
clockwise and release it so that it 
comes out toward you. 
The roll pin behind the key of the operating rod should be seated on 
the cocking piece of the charging handle as shown in the enlarged 
picture in Fig.35 as viewed from the rear of the receiver.  NOTE:  
Do not pull back on the charging handle and release it without the 
bolt carrier and barrel attached to the receiver. Doing may cause 
damage to the parts.

Installation of Barrel 
 
WARNING!  FAILURE TO INSTALL THE BARREL 
PROPERLY MAY RESULT IN DEATH OR 
SERIOUS BODILY INJURY AS WELL AS 
DAMAGE TO THE RIFLE AND OTHER 
PROPERTY  FOLLOW THESE INSTRUCTIONS 
CAREFULLY.   IF THE BARREL DOES NOT STAY 
IN THE FIREARM DURING FIRING, STOP 
SHOOTING IMMEDIATELY.  
The barrel cannot be installed until the operating rod and the gas 
tube have first been installed.   
 
1.  Set the buttstock of the rifle on a 
solid surface with the front of 
the receiver pointing upward in a 
safe direction.   
2. Using your thumb, push the 
barrel release button in as far as

the receiver and onto the gas 
tube as far as it will go. 
6.  Release the barrel release button 
and rotate the barrel back and 
forth until the barrel release 
leaver locks out. When properly 
locked, it should appear as it 
does in (Fig. 37). 
 
34
 
NOTE:  The barrel release button should be roughly parallel with 
the edges of the handguard nearest it (Fig.37).  If it looks like Fig. 
36, the barrel is not locked into place. Rotate the barrel slightly back 
and forth and push it in and pull it out slightly until the barrel release 
pops out.  If the barrel is properly attached, the barrel release button 
should appear as it does in Fig. 37.  If the barrel release does not pop 
out (lock into place), it may be that the gas tube is not seated 
properly.  If this is the case, review the instructions on installing the 
gas tube on page 31. If you are still having trouble, contact the 
manufacturer. 
 Assembly of the Bolt  
1. Place  the  wide 
end of the 
extractor spring 
into its hole in the 
extractor. 
2. Place  the 
extractor in its 
slot on the bolt. 
3. Press  down 
slightly on the 
middle point of
