Faxon Match Series 12.5″ Gunner .338 ARC Pistol-Length Barrel – NP3 Extension

Compact Accuracy and Power in the .338 ARC Platform

The Faxon Match Series 12.5″ Gunner .338 ARC Barrel delivers exceptional performance and precision in a balanced, compact format for modern AR-15 builds. Designed and manufactured in the U.S.A., this premium Match Series barrel brings Faxon’s precision engineering and craftsmanship to the advanced .338 ARC cartridge—offering superb ballistic efficiency, accuracy, and reliability in a versatile 12.5-inch configuration.

Match Series Engineering – Built for Precision

Each Faxon Match Series barrel is crafted from 416-R stainless steel and meticulously honed and lapped for a superior bore finish. The 5R button rifling reduces bullet jacket deformation and fouling, ensuring greater velocity consistency and long-term precision. Faxon’s stringent tolerances and chamber quality provide sub-MOA potential with premium ammunition, making this barrel a proven performer in compact precision builds.

Gunner Profile – Strength, Stability, and Lightweight Control

The Gunner profile combines the lightweight handling of a pencil contour with the strength and heat stability of a government profile. The result is a well-balanced barrel that minimizes weight while maintaining accuracy and durability under extended firing conditions—perfect for field, tactical, and competition use.

Optimized for .338 ARC Ballistics

Chambered in .338 ARC, this barrel delivers excellent ballistic performance and downrange energy in a short, maneuverable format. The pistol-length gas system ensures reliable cycling with or without a suppressor, while the 1:5 twist rate stabilizes heavy, high-BC projectiles for optimal precision. The 12.5″ length offers the ideal balance between compact handling and ballistic velocity for modern .338 ARC applications.

Durable Construction & Protective Finish

Each barrel is precision-machined from 416-R stainless steel and treated with a QPQ nitride finish inside and out for exceptional corrosion resistance and surface hardness. The NP3-coated barrel extension provides a self-lubricating surface that enhances bolt lockup and long-term reliability. Every Faxon barrel undergoes comprehensive inspection to ensure chamber precision, bore alignment, and perfect concentricity.
