Brownells announced new additions to its catalogue, introducing big bore AR-15 barrels in .450 Bushmaster and .458 SOCOM.

The barrels, which Brownell’s commissioned from Faxon Firearms, are coated in a matte black nitride finish and ship with a muzzle brake and bolt. The addition of the bolt means users can swap it into existing platforms.

The .16-inch .450 Bushmaster boasts a button-rifled design crafted from 4150 GBQ mil-spec steel. The barrel offers a .750-inch gas-block journal that works alongside aftermarket components. With a 1-in-16-inch twist, the barrel is threaded so suppressors can be added.

Following the .450 Bushmaster is the .458 SOCOM barrel. Measuring 16-inches, the .458 SOCOM uses the same steel construction as the .450 but with a 1:14 twist rate. The barrel is button-rifled with traditional land-and-grooves, topped off with an 11-degree target crown.

Both barrels are magnetic particle inspected and available from Brownells with a MSRP of $309.
