Shaw Capable

Shaw O.E.M can supply any barrel, to any degree of completion-from simple blanks to finished barrels in any quantity required.  Shaw covers every caliber from .17 to 12-gauge, up to a length of 41 inches, and exclusively utilizes gun-barrel-certified 4140 chrome moly, 416R stainless steel and 4150 mil spec vanadium. Shaw currently produces thousands of configurations, including rimfire, centerfire, and shotgun – all button-rifled. We can precision-drill, ream and rifle to meet all SAAMI specifications and frequently assist our customers in development and design for their finished products. When choosing a supplier, think Shaw– where capacity, capability and quality meet.

Quality Barrel Materials

Shaw O.E.M quality control begins at the steel mill.  Metallurgical engineers design proprietary, specified-chemistry formulations exclusively for our gun barrel applications. When we purchase raw material, we buy an entire heat of steel and maintain complete control of our raw materials so we can ensure consistent quality throughout your entire production run. Our vast on-hand inventory eliminates delays in materials procurement.  This leads to Shaw delivering consistent quality in short turnaround times. 

Experienced Craftsmanship

For over a century, Shaw O.E.M has been designing and manufacturing precision-crafted gun barrels for virtually every small arms manufacturer in the country. Our O.E.M Division is the oldest, most experienced independent barrel manufacturer in the United States. Our commitment to quality craftsmanship is the reason our products have stood the test of time. In our pursuit of perfection, we have pioneered many technological advances-several for which we have been issued U.S. patents and continually reinvest in advanced tooling and have doubled our capacity over the last two years.
