Description

416R Stainless • 1:5 Twist • 5R Rifling • Gunner Profile • Nitride Inside & Out • NP3 M4 Extension

The Faxon Match Series 6" Gunner 300 BLK is designed to maximize the 300 Blackout cartridge’s potential in ultra-compact builds. With a fast 1:5 twist rate and 5R rifling, this barrel stabilizes both heavy subsonic and lightweight supersonic rounds for superior accuracy and terminal performance.

Crafted from 416R stainless steel and treated with salt bath nitride inside and out, this barrel delivers precision, corrosion resistance, and easy cleaning. The Nickel Teflon–coated M4 extension tightens receiver fit and enhances lubricity, while the Gunner profile ensures excellent handling without sacrificing durability.
