Alexander Arms International is an American owned business specializing in firearms, leveraging innovation & expertise to provide our clientele with unwavering performance and unfailing reliability.

Built upon a reputation of innovation, Bill Alexander masterfully developed the .50 Beowulf and 6.5mm Grendel caliber cartridges to improve upon the known AR-15 platform. With our quality-first mindset, we build firearms with the understanding that not only the operator’s life depends on it, but the freedoms that allow us to produce these rifles also depend on it.

With the foundation set on two new cartridges, we have taken our expertise to platforms chambered in 5.56mm NATO, .338 Lapua Magnum and others to bring tailored solutions to your unique mission.
