The Superlative Arms AR-15 Adj Piston System uses the Patented Bleed Off® mode to regulate gas by venting excess pressure out of the front of the gas block. The result is a piston-driven AR-15 that runs cleaner and cooler, with reduced wear on the bolt carrier group and upper receiver while helping manage recoil impulse.
Key Features
Patented Bleed Off® operation vents excess gas out the front of the gas block instead of restricting flow like conventional adjustable blocks
Carbine-length gas system configuration for the AR-15 platform
.625 solid set-screw gas block design for secure installation
Full-auto AR-15 carrier compatibility with Dark DLC carrier finish
External adjustment detent location helps keep adjustment areas cleaner and reduces contamination risk
Designed to reduce erosion or seizing of the adjustment screw in Bleed Off Mode and helps prevent detent loss from carbon buildup
Upgrade your AR-15’s operating system with an adjustable Bleed Off® piston kit designed to help reduce heat, fouling, and wear for smoother, more controlled performance.
