Faxon 10.5″ .300 BLK Gunner Barrel w/ Pinned Gas Block
The Faxon 10.5″ .300 BLK Gunner Barrel w/ Pinned Gas Block is purpose-built for shooters looking to optimize their .300 AAC Blackout build for both suppressed and unsuppressed use. Made from 4150 Chrome Moly Vanadium (CMV) steel and finished with a QPQ Nitride treatment, this barrel delivers outstanding durability, corrosion resistance, and surface hardness. With full in-house manufacturing and precision headspace verification using hardened gauges, Faxon ensures exceptional quality control in every unit.
This model features a Pistol-length gas system optimized for reliable cycling with subsonic and suppressed setups. It includes a pre-notched, pre-drilled journal and a pinned low-profile gas block, ensuring that the gas block won’t rotate or drift under high-round-count conditions. This is a reliable solution for serious shooters who demand peace of mind and rugged construction in the field or at the range.
The Gunner profile strikes the perfect balance between weight reduction and heat management. Designed with a Government taper near the chamber and a pencil-thin front end, this barrel reduces forward weight while retaining thermal mass where it matters most—at the rear. This profile enhances maneuverability and minimizes barrel whip, delivering better control and faster follow-up shots in close quarters or rapid fire scenarios.
