- Videos (3)
The gas piston kit installs easily, requiring no permanent alterations to the rifle, and adds virtually no additional weight to the gun. The kit comes complete with a replacement gas block (with integral single Picatinny top rail), piston and piston return spring, operating rod, solid steel one piece replacement bolt carrier , handguard cap, properly relieved M-4 style handguards, installation hardware and complete instructions. The low profile of the Adams Arms piston design makes it compatible with some free-floating handguards, however removal of some material from the upper portion of the free-float handguard may be required for use with this operating system.
