One Horse OH-15, 5.56 NATO, 16" Barrel, 1-30rd Magazine, Mid-Length Gas, Rifle

The One Horse OH-15 Mid-Length is a refined, duty-ready AR15 built to deliver smooth operation, reliable performance, and real-world versatility. Chambered in 5.56 NATO and equipped with a 16-inch barrel paired to a mid-length gas system, this rifle is tuned for softer recoil impulse, improved reliability, and enhanced shooter control. Designed as a true all-purpose carbine, the OH-15 Mid-Length excels at the range, in training environments, and for home or property defense—all while maintaining an accessible price point. Made in the USA, it reflects a no-nonsense approach to modern AR ownership. What sets the OH-15 Mid-Length apart is its gas system choice. The mid-length configuration offers smoother cycling and reduced wear compared to traditional carbine-length setups, resulting in better controllability and longer component life. The 16-inch barrel provides excellent velocity and accuracy while remaining maneuverable, making it well-suited for both practical shooting and defensive applications. Built around Mil-Spec components, the rifle offers broad compatibility for future upgrades and customization, allowing shooters to tailor the platform as their needs evolve.
