Superlative Arms Piston Kit

The patented “Bleed Off” Superlative Arms piston kit system adjusts the gas flow of your AR-15 rifle by bleeding the gas out of the block instead of restricting the flow like conventional adjustable blocks. This allows the pressure to be reduced only to the amount required to drive the bolt carrier. The remaining pressure is bled out of the block, keeping the system clean and cool. The use of this piston system delivers a reduction of felt recoil and prevents fouling of the receiver. When used with short-barreled rifles or suppressors, the bleed off port allows the excessive pressure to be relieved, reducing gas blowback.
