Now pull the Bolt Carrier Assembly past the Grip Mount to remove it from the rifle.

The Rear Assembly Pins may be pushed back into their housing, keeping the assembly
from closing. The hammer may prevent a cleaning rod from entering the chamber if the
Rear Assembly Pins are aligned with the holes in the receiver as when the rifle is
assembled.
The Forward Assembly Pin may be pushed free with a Dummy Cartridge in the
same way as the Rear Assembly Pins in order to give access to the Gas System and
Ejection Chute. (Note: Do not use excessive force on the Assembly pins!)
Figure 38: Use the nose of the bullet to push out the forward assembly pin
After the Pin is pulled out as far as it will go, firmly grasp the hand guard with one
hand and the barrel with the other, pull the handguard away from the barrel. Do not pull on
the Forward Assembly Pin for leverage as this may damage the pin!

Figure 39: Grasp the barrel with one hand and pull down the handguard
The central assembly pin may be pulled out to remove grip and handguard assembly from
the barrel assembly for cleaning and maintenance. Disassembly of the grip is NOT
recommended. To thoroughly clean the inner crevices of these assemblies, use a polymer-
safe sprayable gun cleaning solution and coat all surfaces. Allow for several moments for
the cleaner to soften accumulated fouling, and then use compressed air to blow out dirt and
particles. Use rags and cotton swabs to clean accessible exposed surfaces. Spray a light
oil onto metal components to prevent corrosion.
To remove the Ejection Chute, with the handguard pulled away from the barrel, gently
press on the right side of the chute in the space underneath the Sight Rail and behind the
gas block.

This will allow the Ejection Chute the to be pulled forward and free of the rifle.
