Faxon Match Series 9" Gunner .300 Blackout 1:5T Pistol‑Length Barrel

Faxon Match Series 9″ Gunner .300 Blackout 1:5T Pistol-Length Barrel – NP3 Extension

Precision-Machined Match Barrel for .300 Blackout Builders

The Faxon Match Series 9″ Gunner .300 Blackout Barrel (SKU: 15B35P9NGQ-5R-NP3) delivers uncompromising accuracy, durability, and balance in a lightweight package engineered for professional builders and serious shooters. Combining Faxon’s Gunner profile with Match-Series manufacturing standards, this barrel offers exceptional precision and consistent performance for pistol-length AR-15 platforms chambered in .300 BLK.

Match-Series Quality & 5R Rifling

Every Faxon Match Series barrel begins as certified 416-R stainless steel and is button-rifled with 5R hybrid rifling—a design that reduces bullet deformation, improves velocity consistency, and enhances accuracy through superior gas seal and reduced fouling. Each bore is honed and lapped to ensure near-mirror smoothness and cold-shot precision right out of the box.

Gunner Profile – Lightweight Meets Stability

Faxon’s signature Gunner profile blends the rigidity of a government-style barrel with the reduced weight of a pencil contour. This optimized geometry shifts mass toward the chamber, improving heat control and harmonics without sacrificing balance or handling. The result: faster transitions, reduced fatigue, and exceptional accuracy retention during rapid fire.

Engineered for Suppressed and Unsuppressed .300 BLK Builds

This barrel’s pistol-length gas system is tuned for reliable cycling in both suppressed and unsuppressed configurations. The 1:5 twist rate stabilizes a broad range of subsonic and supersonic projectiles—from lightweight 110-grain loads to heavy 220-grain subsonics—making it ideal for suppressed use, defensive setups, or compact pistol builds.

Premium Materials & Surface Treatment

Each Match Series .300 Blackout barrel is machined from 416-R stainless steel, heat-treated, and finished with black Nitride inside and out for extended barrel life and corrosion resistance. The extension is coated with NP3 nickel-teflon for ultra-slick lockup and improved corrosion protection within the receiver.
