One Horse OH-15 5.56 NATO Semi-Auto Rifle, 15″ Barrel, Black

Product Description

The One Horse OH-15 is a semi-auto 5.56 NATO rifle with a 15″ barrel and a black finish. It holds 30 rounds and comes with the One Horse M4 6 Position Black A2 stock, so you can set the length of pull to fit your shoulder and your gear.

What sets it apart

The muzzle is threaded 1/2″x28. That means you can add a compatible muzzle device without re-threading the barrel. The barrel has a 1:8″ twist rate. At 7.14 lbs, it is a manageable weight for a full day on the range or a long training course.

This rifle suits shooters who want a straightforward 5.56 NATO semi-auto for practice, classes and general range use. The 30-round capacity keeps you shooting between magazine changes, and the six-position stock makes it easy to share between people of different sizes.

Gear that pairs well includes a sling, an optic, extra 30-round magazines and a padded rifle case. If you plan to run a muzzle device, check that it uses 1/2″x28 threads. Stock up on 5.56 NATO ammunition for the range.
