The Aero Precision Adjustable Low Profile Gas Block in .625" is a precision-engineered gas system component designed to give AR-15 shooters full control over their rifle's gas system. Machined from 4140 steel and finished in a durable black nitride coating, this gas block is built to withstand demanding use while maintaining a slim, low-profile form factor that fits seamlessly under free float handguards, including the Aero Precision ATLAS series. Whether you are running a suppressed build that requires careful management of excess gas and blowback, or a competition rifle where recoil mitigation is key, this adjustable gas block delivers 15 repeatable adjustment settings to dial in your gas system with confidence. The stainless-steel adjustment screw clicks into place via a spring-and-detent mechanism, eliminating the need for secondary set screws that can loosen under recoil. A dedicated sacrificial chamber channels carbon fouling away from critical components to prevent carbon locking, and the fully user-serviceable design makes field maintenance straightforward.
