You’re in Good Company

At Small Arms Manufacturing, we make it our mission to be the best manufacturing partner an OEM could have. Our size and flexibility enable us to provide barrels for your finished firearms, tailored precisely to your needs, and often at lower costs than you could retool for in-house. For many decades, we have been a reliable supplier to many of the country’s foremost small arms manufacturers, as well as the U.S. military. We can produce any barrel you need, in any configuration you require.

Do One Thing and Do It Well

We’ve been around long enough to know that you don’t stay ahead by sitting still. Every piece of our manufacturing equipment has been replaced within the past five years, and we are on the cusp of breaking ground on an entirely new manufacturing facility. We continually search for the finest craftsmen and engineers, intent on exceeding our own current capabilities, as well as the expectations of all our customers.

Small Arms Manufacturing designed and patented helical fluting.

We also hold patents on a number of proprietary tooling and machining processes. We can precision-drill, ream and rifle to meet all SAAMI specifications. We frequently assist our customers in developing specifications for their finished products. We can help you optimize your design for production, safety, quality and cost benefits. We are driven-not by our need to simply manufacture gun barrels-but by our desire to excel at our craft.


Our Engineering & Design Department is at your service.

Whether it’s a large quantity run of rifle, pistol, or shotgun barrels, or a single custom order, we will engineer it precisely to your requirements. Contact us with the details of your requirements.
