Description

Faxon Match Series — 10.5" Gunner 300 BLK AR-15 Barrel (1:8 Twist, Pistol-Length Gas)

416R Stainless • 5R Button Rifling • Gunner Profile • Nitride Inside & Out • NP3 (Nickel Teflon) M4 Extension

The Faxon Match Series 10.5" Gunner 300 BLK delivers match-grade accuracy and fast handling for compact AR-15 builds. The Gunner profile blends Government strength with Pencil agility, keeping weight off the muzzle for faster transitions and less fatigue.

Precision-machined from 416R stainless steel with 5R button rifling (1:8 twist) and treated with salt bath nitride inside & out, this barrel resists fouling and corrosion while maintaining consistent precision. A Nickel Teflon–coated M4 extension enhances lubricity and tightens the receiver fit for improved consistency.
