Product Description

The Superlative Arms Patented Bleed Off® Mode direct impingement gas block for the AR-15, AR-10, and LR-308 platforms adjusts gas flow by bleeding excess gas out the front of the block, unlike conventional blocks that restrict flow. This design reduces internal pressure to only what's needed to cycle the bolt carrier, with excess gas vented forward. The result is a cleaner, cooler system with reduced wear on components, less felt recoil, and improved reliability—especially when using SBRs or suppressors. The adjustment detent is externally located for zero contamination, and the non-restrictive gas screw resists erosion, seizing, and carbon buildup. A built-in safety feature prevents the screw from backing out unintentionally.
