Removal of the gas block assembly is not necessary and is not advisable. The gas
block assembly is factory fitted using special fixtures and torque tools. Attempting
to fit the gas block assembly without the required special equipment can result in
damage to the components and malfunctioning of the rifle.

REASSEMBLY
Again, Be Sure Rifle and Magazine are Completely Unloaded!
1. Reassembly of bolt into receiver:
(BOLT CANNOT BE RE-INSTALLED WITH EJECTOR/BOLT STOP IN PLACE)
a. Bolt can be reinserted by holding it at approximately a 45
o
angle to the
receiver, with the rear end of the bolt angling downward. Insert the tail of the
firing pin through the slot in the receiver bridge, and “wiggle” the bolt until
its rear end moves back into the receiver. Then, push it forward to its closed
and locked position. It should rotate and move freely into place.
b. If you have removed the bolt stop (step 9, p. 25) reinsert the bolt lock plunger
and spring into its hole in the top of the receiver. Depress the plunger until
the rectangular cut in its side lines up with the round hole seen inside the
receiver on the left side. CAUTION! Plunger will now be under spring tension
and could cause injury if suddenly released. While holding the plunger against
its spring in this position, insert the bolt stop until its rectangular “tab” goes
into the rectangular cut on the bolt lock plunger. Sliding the bolt lock cover
plate upward (prying it upward slightly with a screwdriver if necessary)
completes reassembly of the bolt lock. Note that the large inverted triangular
protection on the cover plate goes on the outside
of the rifle.
2. Reinstalling remaining parts of barrel/receiver group:
a. Retract bolt. Replace operating slide by angling the handle portion upward
between the handguard and receiver ring; then lower the slide so that the cam
track on the inside of the rod fits over the roller on the right locking lug of
the bolt, and the tab adjacent to the slide handle goes into its track on the
right side of the receiver.
b. Push operating rod fully forward. Be sure that the gas piston fits into the hole
in the front of the slide.
c. Replace buffer bushing (open end goes toward front) and cross pin. The cross
pin must be below flush with both sides of its hole. Be sure pin stays in place
for next step.
d. Hold action upside down as show in Figure 11b, p. 24. Car
efully insert recoil
spring into hole in rear of slide, and compress the recoil spring until buffer
guide rod can be inserted into buffer bushing (the projection on the guide rod
should be between the buffer bushing cross pin and the barrel).
CAUTION! The recoil spring will be strongly compressed during this step and can
fly out with considerable force, possibly resulting in injury. Keep it under your
control and proceed with care.
