One Horse OH-15 .300 Blackout Pistol, 10.5″ Barrel, 30-Round

Product Description

The One Horse OH-15 is a complete .300 Blackout pistol with a 10.5″ barrel. It is a semi-auto with a 30-round capacity, so you get a full magazine of firepower in a gun built around a short barrel and a brace.

This model comes as a complete pistol fitted with a KAK brace. It has an alloy frame and a manual safety. Unloaded, it weighs 7.985 lbs, which is worth knowing if you plan to add an optic, a light, or other accessories.

Who it suits

The OH-15 fits shooters who want a .300 Blackout pistol without piecing one together from separate parts. It makes sense for range days, home-defense planning, and anyone who likes the handling of a short-barreled platform. The 10.5″ barrel gives you more length than the shortest pistols while keeping the gun easy to move around.

Plan on a few add-ons. A red dot or other optic, a sling, and spare 30-round magazines are the usual starting points. Stock up on .300 Blackout ammunition, and check that any accessory you choose is made for this caliber and platform. Because this is a firearm, it ships to a local FFL of your choice for transfer.
