The Gunner profile is a blend of two of the best performing profiles of all time, Gov't and Pencil. Faxon's Gunner profile combines the durability of the Gov't profile with the weight savings and maneuverability of the Pencil profile. The Gunner profile brings the balance of the rifle back towards the shooter's body, limiting fatigue, and allowing for shooting, training, or hunting all day long.

Faxon Firearms barrels are the pinnacle of value. Manufactured in-house in Cincinnati, Ohio, Faxon barrels are fully stress relieved, air-gauge tested, and 11 degree target crowned to ensure superior accuracy. Quality is imbued into our barrels from the beginning of the manufacturing process.. We start with the best materials, either certified 4150 Mil-Spec steel or 416-R Stainless. From there, each barrel goes through a battery of tests at each operation until finished in Nitride and final inspected. All barrels are individually checked for headspace with precision PTG gauges.

    Match Series 10.5"Gunner 300 BLK Barrel

    Posted by JR on Aug 7th 2023

    Great quality and finish. The Nickel Teflon extension is one of the best I've seen on any barrel. The fit on my VLTOR upper is tight and solid. Best fit of ANY barrel Ive installed on an AR upper. Stupid accurate at 50 Yds. as it is at 100 Yds. I am very happy with the results. Faxon knocks it out of the park with their Match Series. I will be purchasing another Match Series barrel soon!!!

    Amazing Barrel

    This is hands down one of the best 300 blackout barrels I have shot. It's accuracy and reliability are above all of its competitors. And it looks good too.

    The barrel have look and feel like high quality. The fit into my Anderson upper was very tight which is a good thing. I have yet to put any rounds through the barrel as I'm still in the middle of my build.
