Superlative Arms Adjustable Piston System 0.750" Gas Block (Left Hand) for AR-15

Overview

The Superlative Arms patent pending “Bleed Off” adjustable piston gas block for the AR-15 platform adjusts gas flow by bleeding gas out of the block instead of restricting flow like conventional adjustable blocks.

Key results

• Reduces the pressure used in the block to only what is required to drive the bolt carrier; remaining gas/pressure is bled out for a cleaner, cooler-running system
• Reduction of felt recoil
• Patented adjustment detent located outside of the block (no contamination)
• Gas adjustment screw does not restrict gas flow; reduces risk of erosion/seizing and detent loss due to carbon build-up
• Screw is removable, with a safety mechanism to prevent unintentionally backing the screw all the way out
• For SBRs and/or suppressors, the bleed-off port exhausts excessive pressure out of the block to reduce blowback

Not rated for 300 Blackout in pistol length.
