Faxon Firearms Match Series Gunner 300 Blackout 7.5" AR-15 Barrel

The Faxon Firearms Match Series Gunner is a 7.5" replacement barrel for compact AR-15 builds chambered in 300 AAC Blackout. Its Gunner contour retains more material behind the gas block and uses a lighter forward section.

The barrel is made from 416R stainless steel and treated with a black nitride/QPQ finish on the bore and exterior. It is button rifled with a 5R pattern and fast 1:5 twist, and it is listed as magnetic-particle inspected.

A pistol-length gas system is paired with a 0.750" gas-block diameter and 1.9" gas-block journal. The muzzle has 5/8x24 threads and a recessed target crown, while the chamber end uses an M4-pattern barrel extension.

This new-condition standalone AR-15 barrel weighs approximately 0.89 lb. It is a barrel component only, not a complete firearm.
