chamber of the barrel;
Install the
extractor spring and plunger.
19) Using the combination tool's screw
driver, turn the gas cylinder lock screw
counter clockwise. Note that you should not
hold onto the forward handguard for leverage
as you can damage it. Hold onto the barrel
and gas assembly.

an enlarged section that allows the
operating rod lug to be removed from the
channel.
31) Rotate the operating rod slightly toward
the top of the receiver while lifting at the
handle end.

receiver and then hold the bolt at the angle
as shown in figure 33.

extracted lower band pin.
37) Slide the lower band forward.
38) Slide the lower hand guard forward.
