Faxon's Gunner Barrels for the .300 AAC Blackout are made from durable 4150 Chrome moly steel. The unique contour provides good accuracy while maintaining a lightweight design for easy maneuverability. The barrels have the same slim "Pencil" profile from the gas block to the muzzle. However, from the gas block back to the barrel extension, more metal is added for rigidity and to prevent distortion due to heat buildup during prolonged shooting.

The barrels come in three lengths - 7.5", 10.5", and 16". Only the 7.5" and 10.5" barrels have a pistol-length gas port, while the 16" has a carbine-length gas port. Additional specs include a gas port size of .104", a gas block journal diameter of .750", and an outside diameter of 1.9". The barrels have a SAAMI-chambered and 1-8" twist rifling, which stabilizes the full range of 300 BLK bullets. The muzzle has an 11° target crowned profile with 5/8-24 tpi threaded muzzle threads. The black QPQ Nitride finish gives it a sleek appearance, with the NP3-coated barrel extension. The barrel extension has M4 feed ramps.

The unique barrel profile of Faxon's .300 AAC Blackout Gunner barrel helps shift the gun's center of gravity towards the rear, making it easier to maneuver, while still maintaining accuracy.
