Quality without compromise

History of Diamondback

What began as a small, family dream in 1989 grew into a large, 200+ team of passionate shooters sharing the same vision: the production of industry-leading, high-quality firearms at a blue-collar workers budget. Officially established in 2009, Diamondback Firearms is family operated at its core with a demonstrated history of innovation and quality.

Diamondback began by delivering precision machined components to their partnering distributors. What they quickly realized, however, was that they could do more with their top-tier components than anyone else. Soon, they engineered the DB380—one of the smallest micro-compact .380 handguns available. Diamondback has since evolved their weapons systems to include other industry-leading rifles, pistols, components, and more.

With a promise of quality without compromise, Diamondback delivers reliability no matter the world’s circumstances. Their buildings are filled with skilled blue-collar craftsmen who live and breathe firearm perfection. Diamondback is there to deliver exactly what shooters want, how they want it, and do so with the unwavering, sincere commitment to excellence.
