16" Express 5.56/.223 Atrius FRS Rifle (America 250)

Some messages built this country. Some still do. The One Horse Express was born from that same spirit of independence—a rifle carried forward by the people who refuse to wait for permission. Developed in collaboration with Atrius Development Group, every Express rifle is assembled by Americans who believe the details are the difference between good enough and built right.

Engineered and built to a high standard, every rifle in the series leaves our floor with the Atrius Forced Reset Selector professionally fit, timed, tested, and factory installed—Built To Run™. It rides on a 16-inch CrMoV nitride SOCOM-profile barrel with a 1:8 twist, a mid-length gas system with a low-profile staked steel gas block, and an H2 buffer for smooth, dependable cycling. A curved trigger, 15-inch Express-Lock handguard, Breek Arms Warhammer Mod2, and Thril RTG grip and CCS stock round out a platform tuned as a complete system from day one.

This is more than a parts list. It's two American companies, one standard, pushing each other to build better and go further than either could alone. At Atrius Development Group, they say it best: Together we win. And that's exactly what we intend to do—win, with them. Their fight is our fight. The Express is proof of what that partnership delivers: a rifle engineered, assembled, and tuned to be carried forward. Independence isn't inherited. It's carried forward.
