One Horse Medium 5.56 NATO 1:7 Carbine-Length - AR-15 Barrel - 10.5" - $64.99

Description

Build your compact AR-15 on a foundation that performs. The One Horse 10.5-inch 5.56 NATO barrel brings a 1:7 twist, carbine-length gas, and black nitride finish to SBR and home-defense AR builds — a mil-spec construction that handles the unique demands of a short-barreled 5.56 configuration without sacrificing the reliability a compact rifle needs most.

The One Horse 10.5-inch 5.56 NATO Barrel is a compact AR-15 barrel machined from 4150 steel with a medium profile, black nitride finish, and 1:7 twist rate on a carbine-length gas system, designed for SBR, pistol, and home defense builds requiring reliable cycling in a short-barreled format.

Three features make this barrel a dependable core for a compact build. The 1:7 twist rate stabilizes a wide range of 5.56 bullet weights including heavier 62-grain and 77-grain projectiles — the loads that perform best at the reduced velocities generated by a 10.5-inch barrel, where heavy-for-caliber bullets retain terminal energy better than lighter alternatives. Black nitride finish provides enhanced bore and exterior corrosion resistance compared to phosphate, a meaningful advantage in an SBR or pistol build that may be stored for extended periods or used in wet environments. 4150 steel construction and mil-spec machining ensure dimensional compatibility with standard AR-15 upper receivers, gas blocks, and the close-tolerance components common in quality compact builds.

Compatible with mil-spec AR-15 upper receivers and carbine-length gas systems. 1/2x28 threaded muzzle.
