One Horse OH-15 5.56 AR Pistol | 10.5″ Barrel | 30rd

The One Horse OH-15 is a compact AR-style pistol chambered in 5.56mm NATO with a 10.5″ barrel and a 9.25″ M-LOK handguard. Its short profile and KAK brace make it well suited to shooters who need a maneuverable platform for range drills and competitive short-range work. For a practical sighting solution, pair this pistol with a Holosun 510C or a Vortex Sparc AR red dot—both are effective, proven optics available well under $1000.
