About HM Defense

HM Defense & Technology emerged from an established aerospace machining business in Mount Orab, Ohio, leveraging decades of precision manufacturing expertise.

The company grew out of Luxus Arms, LLC, which had been producing high-quality firearms and building complex components for clients including GE's aircraft division.

Under CEO Clay Barker's leadership, HM Defense evolved into a cutting-edge firearms manufacturer specializing in AR-15 rifles and .50 BMG precision rifles.

Over 15+ years, the company has been at the forefront of innovation in firearms manufacturing, holding multiple patents fundamental to AR design.

Today, HM Defense continues advancing military rifle technology to its highest level, serving Special Forces, US and NATO Allied countries with their mission statement of excellence.
