Use the Adams Arms Mid Length Gas Piston Retrofit Kit to convert an existing AR-15 to a self cleaning, free floating piston system. Use of a gas piston system in a modern sporting rifle expels carbon and gases forward and away from the operator. The rifle action remains cool and clean. It eliminates harmonic barrel transfer, and reduces supersonic crack and muzzle flash.

Note: This system requires a mid gas length (9.866" from barrel extension to shoulder) and a .750" gas seat.

It is recommended using a standard barrel nut or barrel nut with similar measurements for proper fit and function of the kit. Many aftermarket proprietary barrel nuts do not offer the clearance for the drive rod or proper seating of the spring and bushing.
