Faxon Match Series 14.5" Gunner 338 ARC Pistol‑Length Barrel

Faxon Match Series 14.5″ Gunner .338 ARC Pistol-Length Barrel – NP3 Extension

Mid-Length Precision for the .338 ARC Platform

The Faxon Match Series 14.5″ Gunner .338 ARC Barrel delivers a powerful combination of precision, control, and efficiency for AR-15 builders who want a perfectly balanced .338 ARC setup. Designed and manufactured entirely in the U.S.A., this Match Series barrel embodies Faxon’s commitment to premium materials, exact machining, and consistent long-range performance in a mid-length configuration.

Match Series Precision Engineering

Every Faxon Match Series barrel starts with 416-R stainless steel that is honed, lapped, and finished to exacting tolerances. The 5R button rifling improves velocity consistency and reduces bullet deformation for superior downrange accuracy. Faxon’s Match chambering process ensures reliable cycling and sub-MOA potential with quality ammunition—making this barrel an outstanding choice for competitive or precision-oriented shooters.

Gunner Profile – The Ideal Balance of Weight and Rigidity

The Gunner profile offers the best of both worlds: lightweight handling and dependable heat stability. Designed to combine the maneuverability of a pencil contour with the strength of a government profile, this barrel maintains consistent accuracy during extended strings of fire while keeping weight manageable for dynamic shooting environments.

Optimized for .338 ARC Ballistics

Chambered in .338 ARC, this barrel is tuned for optimal ballistic performance in a 14.5″ configuration. The pistol-length gas system delivers reliable cycling in both suppressed and unsuppressed platforms, while the 1:5 twist rate stabilizes a wide range of heavy, high-BC projectiles for long-range precision. Builders benefit from consistent energy retention, flat trajectories, and accuracy across real-world shooting distances.

Durability Through Premium Finishes

Each barrel is machined from 416-R stainless steel and treated with a QPQ nitride finish inside and out to resist corrosion, carbon buildup, and wear. The NP3-coated barrel extension offers a smooth, self-lubricating surface that improves bolt lockup and reliability over thousands of rounds. Every Faxon barrel is subjected to rigorous inspection to confirm headspace precision, bore uniformity, and chamber alignment.
