One Horse OH-15 Complete Upper Features The One Horse OH-15 Complete Upper is built around a 10.5-inch 4150 steel medium profile barrel with a 1:7 twist rate delivering the heat resistance durability and dimensional consistency that 4150 steel is known for in demanding tactical and close-quarters AR-15 applications. A pistol-length gas system is specifically optimized for reliable and consistent cycling with .300 Blackout ammunition across both supersonic and subsonic load profiles making this upper an outstanding foundation for a dedicated suppressed or unsuppressed compact .300 Blackout pistol build. The 5/8x24 threaded muzzle accepts a wide range of aftermarket muzzle devices and suppressors keeping the upper fully suppressor-ready to take full advantage of .300 Blackout s outstanding subsonic performance. The 10-inch handguard provides a free-float platform that eliminates barrel contact for maximum accuracy potential while delivering an extended and stable gripping surface for a consistent support hand position across a wide range of shooting positions and applications. The compact 10.5-inch barrel and 10-inch handguard combination delivers an exceptionally maneuverable and close-quarters-ready profile that is purpose-built for vehicle carry home defense and suppressed shooting applications. The complete upper format delivers a ready-to-install assembly that drops directly onto any mil-spec AR-15 lower for a fast and straightforward pistol build or upgrade. Designed for AR-15 pistol builders and .300 Blackout enthusiasts who want a compact and suppressor-optimized complete upper without the complexity of individual component sourcing the One Horse OH-15 Complete Upper delivers an exceptional combination of barrel material gas system configuration and handguard length in a single ready-to-run package. The medium barrel profile and pistol-length gas system pairing is one of the most proven configurations for compact .300 Blackout pistol builds delivering reliable performance with the full spectrum of .300 Blackout loads. For builders who demand quality and performance in a compact .300 Blackout pistol upper the OH-15 Complete Upper is the definitive choice.
