One Horse Express M-LOK 5.56 NATO 10.5" 30rd Atrius FRS Pistol

Built on a 10.5 inch medium profile barrel in 5.56 NATO (listed for 5.56/.223), the One Horse Express M-LOK is an AR pistol with an M-LOK handguard and a single side Atrius Forced Reset Selector in place of the usual safety. That selector has safe, semi and forced reset positions. It works with the pistol's fire control group rather than replacing the trigger, and in the forced reset position the selector returns the trigger to its ready point after each shot as the bolt carrier cycles.

The selector is fitted, timed and tested on this pistol before it goes out, and every gun is test fired, so nothing is left to install or tune. Gas runs through a carbine length system, and the 1/2x28 threaded muzzle wears an A2 muzzle device. The charging handle is a Breek Warhammer Mod2, an ambidextrous design, and the grip is a THRiL RTG Rugged Tactical Grip on a milspec buffer tube. It comes in black with one 30 round magazine.
