The Built To Run™ Express Rifle is designed around the Atrius Forced Reset Selector and tuned as one system.
BROWNSTOWN, Ind. — One Horse, a rapidly growing American firearms manufacturer, announced the launch of its exclusive One Horse Express Rifle, a factory-built production rifle built around Atrius Development Group’s revolutionary Forced Reset Selector (FRS).
Rather than simply adding components to an existing platform, the One Horse Express is designed, assembled and tuned from the ground up as a complete system to deliver maximum reliability, consistency and performance right out of the box.
The One Horse Express became available on June 19, 2026.
The One Horse Express key features:
“This rifle was Built To Run™,” said Jeremy Hammons, CEO of One Horse. “The One Horse Express represents a significant step forward for One Horse and for production rifle manufacturing. This collaboration pairs Atrius’ selector technology with a rifle platform engineered, assembled and tuned as a complete system from day one. Atrius and One Horse share the same standard: disciplined manufacturing, dependable performance and a finished product the end user can trust and be proud to own.”
“Since day one, the Atrius Forced Reset Selector has set the standard for what is possible in this industry,” said Ryan Spadafore, CEO and founder of Atrius Development Group. “Partnering with One Horse is the kind of move that changes the conversation. They represent what we respect in American manufacturing: family ownership, precision-driven production and a commitment to performance. This launch is more than a new rifle. It is an example of the industry working together to move gun culture in a positive direction. We’re proud to stand alongside One Horse as we take that next step together. Together we win.”
