The Superlative Arms Patented Bleed Off® Mode, gas piston system for the AR-15 platform adjusts the gas flow by bleeding the gas out the front of the block instead of restricting the flow like conventional adjustable blocks.

RESULTS:
> The pressure used in the block is reduced only to the amount required to drive the bolt carrier. The remaining gas and pressure are bled out of the block allowing the system to run much cleaner and cooler.
> Reduction of wear on the bolt carrier group components and upper receiver.
> Reduction of felt recoil allowing for faster follow-up shots.
> Patented adjustment detent is located outside of the block and therefore no contamination.
> In Bleed Off Mode the gas adjustment screw does not restrict the gas flow; therefore, there is no erosion or seizing of the screw, and no loss of detent due to carbon build up. Although it is removable, we have added a safety mechanism, which stops you from unintentionally backing the screw all the way out.
> When using SBR’s, the Bleed Off port allows the excessive pressure to be exhausted out of the block reducing blow back.

NOTE: The Superlative Arms Piston Kit does not come with a Bolt Assembly (bolt, cam pin, firing pin, or firing pin retainer). Bolt Assembly sold separately.

***NOTICE: PRIOR TO PURCHASING THIS PRODUCT*** Please review the barrel schematic for the critical dimensions necessary to safely operate the pistol length piston system. There is no industry standard for the distance between the barrel extension to the center of the gas hole. This is critical for the op rod length. If it is not the same distance as stated on the schematic, you may bend the op rod. However, we can cut you a special op rod to fit your setup. Please call for details.
