11-degree target crown, MPI Inspected

The Faxon .300 BLK 16″ Gunner Barrel is an excellent all-purpose barrel for shooters who demand lightweight handling, consistent accuracy, and rugged reliability. Machined from 4150 Chrome Moly Vanadium (CMV) steel and finished with a corrosion-resistant QPQ Nitride treatment, this barrel is designed to withstand extreme use in both suppressed and unsuppressed platforms. Faxon’s Nickel Teflon coated M4 feed ramp extension enhances durability and improves reliability with a wide variety of ammunition.

Each barrel is 100% made in-house from gun-barrel-quality bar stock and undergoes meticulous quality assurance testing. Every unit is individually checked for proper headspace using precision custom hardened gauges, and is MPI (Magnetic Particle Inspected) for structural integrity.

Optimized with a carbine-length gas system, the Faxon 16″ .300 BLK Gunner Barrel is a reliable choice for hunters, home defenders, and tactical shooters alike. The 11-degree target crown further enhances accuracy by ensuring a uniform exit of gasses at the muzzle, reducing dispersion and improving shot consistency.

Just what is the Gunner profile?

The Gunner profile represents the ideal balance between durability and lightweight performance. Starting with a Government taper from the extension to the gas block, the profile transitions to a 0.75″ gas block journal and a pencil-thin front end. This shift moves weight closer to the shooter’s body, improving balance and reducing front-end fatigue. The result is a versatile, maneuverable barrel that excels in any shooting environment without compromising heat control or accuracy.
