One Horse OH-15 | 5.56 NATO | 16" | 15" M-LOK | 30rd Rifle

The One Horse OH-15 (MPN: OH-OG02) is a 5.56 NATO AR-15-style rifle configured with a 16-inch SOCOM-profile barrel, carbine-length gas system, and 15-inch M-LOK handguard. Compared with the OHOG01 mid-length model, OHOG02 places greater emphasis on the full-length handguard and carbine-gas configuration while retaining the same familiar OH-15 controls and adjustable stock.

One Horse specifies a 1:8 barrel twist, 1/2x28 muzzle threads, A2 muzzle device, mil-spec buffer tube, A2 grip, and six-position One Horse M4 stock. The top Picatinny rail provides an optic-ready mounting surface, while the long M-LOK handguard offers ample space for compatible accessories. One 30-round magazine is included, and listed product weight is approximately 7.14 pounds.
