Faxon Firearms has announced the expansion of the balanced and versatile Gunner profile to new calibers. The expansion of the Gunner profile includes 300 BLK, and 7.62×39 for the AR-15. The Gunner profile is designed as a lightweight balanced profile for uses from plinking to competition and combat.
The barrel features a near-continuous taper from the extension to the muzzle improving barrel harmonics. From the
rear to the gas block, Faxon uses well respected “Government” profiles developed for duty use. From the gas block
forward, the barrel’s profile is reduced to the minimum needed to retain rigidity and accuracy. The result is a
balanced, highly mobile, and maneuverable barrel that is full-auto and suppressor rated.
Different from the 5.56 Gunner profile barrels, the new .300 bore offerings move to a .750” diameter gas block
journal. The change is needed to feature concentric 5/8×24 threads common for the calibers. The gas block journal is
1.9” long, perfect for front sight bases, direct impingement, and piston gas blocks.
All of Faxon’s 300 BLK and 7.62×39 barrels feature a 1/8 twist, conventionally rifled 100% in-house by Faxon
under our numerous quality certifications. The Gunner profile barrels will be available in 4150 steel across various
lengths. “With the enthusiastic response to the original Gunner series barrels in 5.56, it just made sense to expand the profile
to new calibers,” remarked Bob Faxon, President of Faxon Firearms. “The Gunner barrels are a fantastic balance of
weight, accuracy, maneuverability. We also paid special attention to ensure adequate material for heavy-duty and
