The Faxon Match Series 11.5" Gunner Profile .338 ARC Barrel brings match-grade performance to compact AR platforms where a balance of handling and ballistic performance matters. Built 100% in-house in Cincinnati, Ohio, this barrel combines premium metallurgy, precision manufacturing, and practical short-barrel ergonomics.
Constructed from 416R stainless steel with a stout 1:5 twist optimized for heavy .338 ARC projectiles, each barrel is stress-relieved, air-gauge tested, MPI inspected and finished in Black Nitride for long-lasting durability. The Gunner Profile blends Gov't rigidity with Pencil-like weight savings to return the rifle's balance toward the shooter for reduced fatigue during extended use.
For optimal feeding and minimal upper modification, we recommend pairing this barrel with our optimized .338 ARC upper — Faxon .338 ARC optimized upper.

Important Product Note
Some customers may need to adjust their upper receiver feed ramps to ensure reliable feeding, particularly when using Hornady Sub-X ammunition. For best results, Faxon recommends using Duramag magazines designed for 400 Legend. We also recommend pairing this barrel with our .338 ARC optimized upper to minimize fitment work. Always verify compatibility with your upper receiver and consult a qualified gunsmith if needed. Faxon Firearms is not responsible for issues resulting from improper installation or non-recommended component pairing.
