Availability: In Stock
The Faxon Firearms Big Bore .458 SOCOM 10.5" 1-14 Gunner Contour Barrel is purpose-built for shooters serious about big-bore AR-15 builds. If you're stepping up to one of the hardest-hitting intermediate cartridges available in the AR platform, this barrel delivers the durability and precision you need. Chambered in .458 SOCOM and fitted with a pistol-length gas system, it's engineered to handle the serious pressures that come with large-caliber shooting while maintaining the handling characteristics hunters and precision shooters demand from a shorter barrel profile.
Built from 4150 CMV steel and finished with salt-bath Nitride treatment, this barrel resists corrosion and wear in field conditions. The button-rifled bore ensures consistent accuracy, while the 1:14 twist rate is optimized for .458 SOCOM ammunition. A threaded muzzle and 11-degree target crown round out a barrel that's equally at home at the range or in the field, giving you flexibility for suppressors, muzzle devices, or precision shooting setups.
The 10.5-inch length strikes a balance—short enough for compact handling and quick target transitions, yet long enough to generate the velocity the .458 SOCOM needs for effective terminal ballistics. Whether you're building a specialized hunting rifle, a close-range thumper, or exploring what the big-bore AR platform can do, Faxon's Gunner series delivers the precision and toughness to keep up.

.458 SOCOM is a big-bore intermediate cartridge designed specifically for the AR-15 platform. It delivers significantly more stopping power than standard 5.56 NATO out of a short barrel, making it popular with hunters, home-defense builders, and shooters who want maximum terminal performance from an AR-platform rifle.
This barrel is designed for AR-15 pattern rifles and features a pistol-length gas system. However, .458 SOCOM typically requires a larger bolt and carrier than standard 5.56 builds, so verify your upper receiver and bolt carrier compatibility before purchase. This barrel itself is the chamber and bore component; your overall build compatibility depends on your upper receiver and bolt setup.
Yes—the barrel features a threaded muzzle, which allows you to attach a suppressor, muzzle brake, or other muzzle device. Verify that your chosen device is rated for .458 SOCOM pressures and that it will work with your specific build configuration.
The salt-bath Nitride finish penetrates the steel surface to create a hard, corrosion-resistant layer that also reduces friction and wear. It's a durable, field-proven finish that protects the bore and exterior without adding thickness like some coatings do.
