Frequently Asked Questions
Will this gas block fit my AR-15 barrel?
This gas block is designed specifically for AR-15 barrels with a .750" outer diameter at the gas port. This is one of the most common barrel diameters for standard and government-profile AR-15 barrels. Before purchasing, measure your barrel's outer diameter at the gas port location to confirm compatibility. It is not intended for .625" pencil-profile barrels or .936" heavy/bull barrels.
Is this gas block compatible with free-float handguards?
Yes — the low-profile design is specifically intended to work with free-floating handguards, including M-LOK, KeyMod, and Picatinny rail systems. Because it sits flush against the barrel without any protruding sight tower, it clears the inside diameter of most modern free-float tubes, making it an excellent drop-in upgrade for minimalist and tactical builds alike.
How is the CMC Low Profile Gas Block installed?
This gas block uses a set screw mounting system. Installation involves removing your existing gas block or front sight base, aligning the new block's gas port with your barrel's gas port, and tightening the set screws to the manufacturer's specified torque. For best results, use a properly sized hex key, apply a drop of medium-strength thread locker to the screws, and verify port alignment before final tightening. Professional installation is recommended if you are unfamiliar with AR-15 gas system components.
