One Horse OH-15 6mm ARC Complete Rifle | 18″ Barrel | 15″ M-LOK Handguard | Mid-Length Gas | 30rd Mag

The One Horse OH-15 in 6mm ARC is a purpose-built carbine engineered for shooters who demand long-range precision and real-world versatility without the bulk or cost of a full DMR platform. Chambered in the flat-shooting, suppressor-friendly 6mm ARC, this American-made rifle delivers exceptional consistency from close quarters to extended steel sessions — all at a price point that outperforms the competition.

Built around an 18″ HBAR barrel with a 1:7 twist rate and 5/8×24 muzzle threads, the OH-15 is ready for a suppressor or muzzle device upgrade right out of the box. The mid-length gas system provides smoother cycling and reduced felt recoil compared to carbine-length alternatives, while the 15″ M-LOK handguard offers ample real estate for lights, lasers, and accessories. A mil-spec buffer tube, One Horse M4 6-position stock, and A2 grip round out a no-nonsense, battle-tested furniture package.
