One Horse OH-15 .300 Blackout Pistol, 7.5″ Barrel, 30+1-Round

Product Description

The One Horse OH-15 is a complete .300 Blackout pistol with a 7.5″ barrel and a 30+1-round capacity. It is a semi-auto and comes with a KAK brace, so it is built as a finished pistol rather than a project.

What stands out

The short 7.5″ barrel keeps the overall package handy, and .300 Blackout is a cartridge made for short barrels. The finish is black. A manual safety is fitted, which gives you a positive way to keep the pistol safe between strings of fire. At 7.985 lbs, it has some heft, and that weight can help it sit steady on the bench or at a barricade.

This pistol suits shooters who already like the .300 Blackout round, or who want to try it in a platform that is ready to run. It works for range days, drills, and general-purpose use. The 30+1 capacity means fewer stops to reload during a session.

Gear that pairs well with it includes a red dot or a magnified optic, a sling, extra magazines, a padded case, and a supply of .300 Blackout ammunition. Pick optics and accessories that match your plans for the pistol, and check fit before you commit to a mount or a muzzle device.
