One Horse OH-BR07 AR-15 5.56 NATO 7.5" 1:7 Pistol Barrel

The One Horse OH-BR07 is a compact 7.5" AR-15 barrel chambered in 5.56 NATO, designed for short-barrel pistol and SBR platforms where a shorter overall length is desired.

Featuring a 1:7 twist rate, this barrel uses a matched pistol-length gas system to cycle reliably in compact AR-15 builds.

The barrel is finished in nitride for enhanced wear and corrosion resistance, and is machined in a medium profile. Made in the USA, the OH-BR07 weighs approximately 1.1 lbs and provides a solid foundation for building a compact AR-15 pistol or short-barrel rifle.
