Faxon Match Series 11.5″ Gunner .338 ARC Pistol-Length Barrel – NP3 Extension

Precision and Power in a Compact Platform

The Faxon Match Series 11.5″ Gunner .338 ARC Barrel delivers exceptional ballistic performance in a compact, maneuverable design ideal for modern AR-15 pistol and SBR builds. Designed and manufactured entirely in the U.S.A., this barrel brings the superior accuracy and energy retention of the .338 ARC cartridge to short-format platforms—offering unmatched versatility for hunting, tactical, and precision applications.

Match Series Craftsmanship – Built for Accuracy

Each Faxon Match Series barrel is precision-machined from certified 416-R stainless steel, honed, and lapped to a mirror-smooth bore finish. The 5R button rifling minimizes bullet deformation and fouling, improving velocity consistency and long-term precision. Faxon’s attention to chamber geometry and concentricity ensures reliable feeding and sub-MOA potential with high-quality ammunition.

Gunner Profile – Lightweight Balance, Duty Strength

The Gunner profile combines the weight savings of a pencil contour with the rigidity of a government profile. This design provides superior balance and handling while maintaining accuracy under heat. Optimized for the .338 ARC, it offers improved stability for rapid follow-up shots and reduced fatigue during extended use.

Optimized for .338 ARC Ballistics

Chambered in .338 ARC, this barrel achieves excellent downrange energy and superior ballistic performance in a short configuration. The pistol-length gas system ensures dependable cycling with or without a suppressor, while the 1:5 twist rate stabilizes heavy, high-BC projectiles for maximum long-range consistency. The 11.5″ length offers a balance of compactness and ballistic efficiency for field or range use.

Premium Materials & Protective Finishes

Crafted from 416-R stainless steel and finished in QPQ black nitride inside and out, this barrel offers exceptional corrosion resistance and surface hardness. The NP3-coated barrel extension provides a self-lubricating interface for smooth bolt operation and long-term reliability. Every barrel undergoes rigorous inspection to ensure concentricity, headspace precision, and flawless bore finish.
