Superlative Arms .875 Adjustable Gas Block – Set Screw – Stainless Steel – Matte Finish
Precision meets innovation with the Superlative Arms Patented Bleed Off® Adjustable Gas Block—crafted for direct impingement systems on AR-15, AR-10, and LR-308 platforms. Unlike conventional adjustable blocks that restrict gas flow, this advanced design vents excess gas forward, dramatically reducing internal pressure, heat, and carbon buildup.
The result? A cleaner-running rifle with smoother cycling, reduced recoil, and extended component life. Whether you’re running suppressed, shooting an SBR, or simply want precision control over your gas system, this solid set screw gas block delivers elite-level performance with minimal maintenance.
Made from rugged 416 stainless steel and finished in a sleek matte, this low-profile block is built for durability and engineered for shooters who demand reliability and refinement.
Patented Bleed Off® TechnologyVents excess gas forward, reducing heat, carbon buildup, and blowback for cleaner, cooler operation.
30 Locked Adjustment PositionsFront-mounted screw allows precise gas tuning for suppressed or unsuppressed setups.
External Detent SystemAdjustment detent is located outside the block, eliminating contamination and carbon lock-up.
Suppressor & SBR OptimizedBleed Off port exhausts excessive pressure, improving comfort and reliability in short-barreled or suppressed configurations.
No Screw Erosion or SeizingAdjustment screw doesn’t restrict gas flow, preventing wear and ensuring long-term reliability.
Built-In Safety MechanismPrevents accidental removal of the adjustment screw during operation.
