One Horse OH-15 Features The One Horse OH-15 Complete Pistol is built around a 7.5 inch medium profile barrel chambered in 5.56 NATO giving it a compact overall length while retaining reliable ballistics for its size. A 1:7 twist rate stabilizes a wide range of 5.56 bullet weights from lightweight varmint loads to heavier match projectiles giving the pistol versatility across ammunition types. The carbine length gas system cycles the action using gas pressure tuned for a shorter barrel keeping the pistol running reliably with standard 5.56 ammunition. A 1/2x28 threaded muzzle wears an A2 muzzle device from the factory and accepts aftermarket compensators or suppressor mounts without additional machining. Finished in a nitride coating over an aluminum receiver the OH-15 resists corrosion and wear better than a standard phosphate finish while keeping the rifle s overall weight down. It ships with a KAK brace attached to a mil-spec buffer tube giving shooters a stabilizing platform for one handed operation without the requirements of a stock. An A2 grip provides a familiar ergonomic hand position that most AR shooters are already accustomed to. Weighing 7.14 pounds and shipping with a 30 round magazine for 30+1 capacity the One Horse OH-15 is a complete ready to run package for shooters seeking a compact 5.56 pistol for defensive or recreational use.
