Rosco Manufacturing

About Rosco Manufacturing

Rosco Manufacturing has been a trusted name in firearms manufacturing for over two decades, originally operating as ESS Solutions for 15 years before rebranding in 2016.

The company operates from a state-of-the-art 50,000+ square foot production facility in Central Falls, Rhode Island, where they manufacture high-quality AR-15 barrels and components.

Founded on the principle "We either do it right, or not at all," Rosco has built their reputation as one of only three American manufacturers certified to produce contract-bid-eligible, mil-spec 5.56mm barrels.

Today, 80% of their business involves OEM manufacturing for major firearms companies worldwide, while 20% focuses on direct-to-consumer sales under the Rosco brand.

The company continues to embody their motto "Americans by birth, shooters by right, and rebels by choice" while delivering their signature #AffordableAccuracy to customers nationwide.
