Adams Arms Gas Piston Conversion Kit AR-15 .750" Picatinny Gas Block

The Adams Arms Gas Piston Conversion Kit with Picatinny Gas Block features a patented one-piece bolt carrier with a picatinny gas black designed for three stages of use (full gas for standard fire, half gas for suppressed, no gas for single shot). The gas system is self-cleaning, and keeps carbon and gases from being expelled towards the shooter. This system does not vent directly to atmospheric pressure. This eliminates the flash signature as well as super sonic crack which is optimal for night vision and suppressed fire. The Adams Arms Piston Conversion Kit no longer requires the receiver bushing or installation dowel.
