The Aero Precision Low-Profile Adjustable Gas Block gives shooters precise control over their AR-15 or AR-10/LR-308 gas system, making it an ideal upgrade for suppressed builds, competition rifles, and any application where fine-tuning gas flow is critical. Machined from durable 4140 steel and finished in a tough Black Nitride coating, this gas block is compatible with barrels featuring a .750 gas block journal. Its low-profile design slips seamlessly under slim free-float handguards, including the Aero Precision ATLAS series, while the stainless-steel adjustment screw delivers 15 repeatable gas settings through audible, detent-indexed clicks. A built-in sacrificial chamber channels carbon fouling away from the adjustment mechanism, helping prevent carbon locking and providing an access point for solvent if service is ever needed. The user-serviceable design ensures long-term reliability and easy maintenance. Each unit ships with the assembled gas block, a 6" 3/32 hex adjustment wrench, and a replacement spring and detent.
