One Shot Gunworks OH-BR07 7.5″ 5.56 NATO Pistol Barrel – 1:7 Twist

The One Shot Gunworks OH-BR07 is a compact 7.5-inch 5.56 NATO barrel designed for AR-15 pistol builds where maneuverability and reliability are top priorities. Featuring a fast 1:7 twist rate, this barrel is well-suited for stabilizing a wide range of projectile weights commonly used in 5.56 NATO and .223 Remington chamberings. The shorter 7.5-inch profile makes it an ideal choice for AR pistol configurations, SBR builds (where legally permitted), or close-quarters setups where a reduced overall footprint is essential.

Whether you’re assembling a custom AR pistol from the ground up or upgrading an existing build, the OH-BR07 delivers a dependable foundation at a competitive price point.
