There's a lot to like about a straightforward AR that just runs, and that's exactly what the One Horse OH-15 is going for. This is a complete 5.56 NATO carbine built in the USA with mil-spec components, a 16 inch SOCOM-profile barrel, and a carbine-length gas system that keeps the whole package light and quick handling. Chambered for 5.56 NATO, it also feeds .223 Remington without a fuss, which means cheap range ammo one weekend and quality defensive loads the next, all through the same rifle.
The 15 inch free-float M-LOK handguard is the standout feature at this end of the market. It covers nearly the full length of the barrel, giving you a long, comfortable grip surface and plenty of real estate for a light, sling mount, or hand stop wherever you like them. Up front you get a 1/2×28 threaded muzzle with an A2 flash hider, so swapping to a different muzzle device or adding a suppressor down the road is simple. The 6-position adjustable stock rides on a mil-spec buffer tube, and the whole rifle accepts standard AR-15 parts, which makes it an easy platform to customize as your needs change. A 30-round Magpul magazine comes in the box, and it takes common AR mags from there.
This is the rifle for range days, training classes, home defense duty, or just having a dependable 5.56 on hand without spending big money. One Horse builds their rifles and components in America with US-sourced materials, and this carbine reflects that no-frills approach: proven configuration, solid parts, nothing gimmicky. If it's your first AR, it covers all the bases. If it's your fifth, it makes a great truck gun or loaner that you won't baby. Either way, mount an optic, zero it, and go shoot.
Yes. The OH-15 is chambered in 5.56 NATO, which means it safely handles both 5.56 and .223 Remington ammunition. That gives you plenty of flexibility, from budget-friendly plinking ammo to premium defensive loads. Brass-cased ammo from reputable brands tends to give the most consistent cycling.
It is. The OH-15 is built to mil-spec dimensions, so it accepts common AR-15 magazines, stocks, triggers, grips, and other components. The 15 inch M-LOK handguard also gives you plenty of mounting space for lights, sling attachments, and other accessories without needing any special adapters.
One Horse builds its rifles and components in the United States using US-sourced materials. The company puts an emphasis on domestic manufacturing and quality control across its whole lineup, and the OH-15 carbine follows that same approach.
Yes. The 16 inch barrel comes threaded 1/2×28 with a standard A2 flash hider installed, which is the most common thread pitch for 5.56 muzzle devices. Swapping to a brake, comp, or suppressor mount is a quick job with basic tools.
