One Horse Express/Atrius .223 Rem Pistol, 10.5″ Barrel, 30-Round

Product Description

The One Horse Express/Atrius is a .223 Rem pistol with a 10.5″ barrel and a 30-round capacity. It comes in black and is set up for M-LOK accessories. That gives you a short, easy-to-handle platform in a common rifle caliber.

The 10.5″ barrel is the main thing to look at. It keeps the pistol short, which helps in tight spaces and when you move between positions on the range. The 30-round capacity means fewer stops to reload during a drill or a practice session.

Who it suits

This pistol fits shooters who like the handling of a short rifle-caliber gun and want to add their own accessories. The M-LOK mounting lets you set it up the way you shoot. It also works for anyone building a range pistol around a light, a sling or a sight.

For gear, start with extra 30-round magazines and a sturdy sling. M-LOK-compatible lights, grips and rail sections are the common next step. A red dot or other optic is a popular addition for faster target pickup. Add hearing and eye protection, a padded case and plenty of .223 Rem ammunition for practice.

Because this is a firearm, it ships to a local FFL of your choice for transfer. Check your local and state rules on pistols before you order.
