Adams Arms Gas Piston Conversion Retrofit Kit AR-15 Rifle Length with .750" Diameter Single Rail Gas Block
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.
