The One Horse OH-15 Complete AR-15 Pistol 5.56mm pairs a compact 10.5" threaded barrel with a 9.25" M-LOK handguard to deliver a maneuverable, dependable AR platform. Built around a carbine-length gas system with a medium-profile barrel and A2 muzzle device, this pistol is designed for smooth cycling, consistent accuracy, and easy accessory mounting along the full-length top rail. This OH-15 configuration is well suited for home defense setups, training, and range use where a shorter overall length and fast handling are priorities. The KAK brace and A2 grip provide a familiar, stable interface, while the included 30-round magazine keeps you shooting longer between reloads. One Horse's attention to reliable function and practical design makes this pistol a solid choice for shooters who value straightforward performance and modern AR ergonomics.
