One Horse builds the rifle. Atrius pushes it further. The partnership behind the One Horse Express Series brings together American manufacturing and precision innovation — so what reaches your hands is professionally installed, factory tested, and built to run.

The One Horse Express delivers unmatched speed, precision, and reliability in every shot. Purpose-built for serious performance and professionally installed to the highest standards, it offers uncompromising quality and confidence you can count on. Designed for shooters who demand excellence, the One Horse Express stands ready when performance matters most.

The One Horse Express Series isn't just a firearm. It's a statement. Engineered in Brownstown, Indiana and built to a standard most manufacturers won't commit to, every firearm in the series leaves our floor with the Atrius Forced Reset Selector professionally installed.
Installing a Forced Reset Selector isn't always plug-and-play. Done wrong, it doesn't run. Every One Horse Express rifle has the Atrius FRS fit, timed, and tested at the factory — so you're not troubleshooting at the range. You're shooting.

Built on the One Horse Express. The Breek Arms WARHAMMER Mod2 ambidextrous charging handle — 7075 aluminum construction, wide set-back latches that clear any optic, and textured grooves that grab even with heavy gloves. Simple upgrade. Serious function. This is the hardware we trust on our rifles.

The CCS stock delivers a rock-solid cheek weld, smooth length-of-pull adjustment, and the kind of lightweight durability that holds up shot after shot. Paired with the THRIL RTG grip, it gives the rifle a balanced, confident feel in the hand—tough enough for whatever comes next.
