850051342549 SUPERLATIVE ARMS LLC AR-15 ADJUSTABLE PISTON SYSTEM W/0.750" GAS BLOCK LEFT HAND The Superlative Arms patent pending “Bleed Off”, direct impingement, gas block for the AR15 platform adjusts the gas flow by bleeding the gas out of the block instead of restricting the flow like conventional adjustable blocks. NOT RATED FOR 300 BLACKOUT IN PISTOL LENGTH Results: The pressure used in the block is reduced only to the amount required to drive the bolt carrier. The remaining gas / pressure are bled out of the block allowing the system to run much cleaner and cooler. Reduction of felt recoil. Patented adjustment detent is located outside of the block and therefore no contamination. The gas adjustment screw does not restrict the gas flow; therefore there is no erosion or seizing of the screw / 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 and / or suppressors the bleed off port allows the excessive pressure to be exhausted out of the block reducing blow back.

Description:

Enhance your AR-15's performance with the Superlative Arms Adjustable Piston System!

The Superlative Arms Adjustable Piston System is designed to optimize the AR-15 platform, providing a unique solution for gas flow management. With its patent pending “Bleed Off” gas block, this system allows for a cleaner and cooler operation compared to conventional adjustable blocks.

Key Features:

  • Cleaner Operation: Excess gas and pressure are expelled, resulting in less fouling and cooler running temperatures.
  • Reduced Recoil: Experience a noticeable reduction in felt recoil during operation.
  • Patented Adjustment Detent: Located outside the block to prevent contamination.
  • Durable Gas Adjustment Screw: Does not restrict gas flow, preventing erosion or seizing, and avoids loss of detent due to carbon build-up.
  • Safety Mechanism: Prevents unintentional backing out of the adjustment screw.
  • Bleed Off Port: Effectively reduces blowback when using SBRs and/or suppressors.
