Faxon Duty Series 10.5", Gunner, 7.62x39 Russian, Carbine-Length, 4150 QPQ Nitride AR-15 Barrel

(3 reviews)
Current Stock:

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.

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.

    Otherwise Excellent Barrel, But Over-Gassed

    Posted by Ageless Yankee on Apr 9th 2019

    Excellent barrel in terms of fit and finish, accuracy, and ease of cleaning. My only complaint is that the gas port seems to be oversized. While my pistol cycles perfectly with an H2 buffer, the recoil is sharp and punishing. It teels like the buffer spring is being fully compressed to a solid, non-yielding cylinder on every shot. After less than 200 rounds, I'm seeing signs of abnormal wear (rounding) on the backs of the bolt lugs.

    Faxon 10.5 gunner 7.62x39

    As usual the barrels from Faxon come with an obvious attention to machine work and finish. Accuracy is as expected with these excellent barrels and I will most certainly continue to add them to my builds.

    Best 7.62x39 Barrel on the Market

    Posted by Varner Teel - Steel Arms Industries on Sep 29th 2017

    This is a great barrel, the quality, percision and accuracy can't be beat. Ran this barrel on an SBR and Pistol, have ran several hundred rounds from Steel, Brass & handloads. Never let me down, cylced through everything like butter. The accuracy at 100 yds is pretty amazing
