Rock River Arms

In 1996, brothers Mark and Chuck Larson founded Rock River Arms in an 1,800 square foot shop in Cleveland, Illinois. Rock River Arms soon developed a reputation as one of the finest builders of hand fitted custom 1911 pistols, and their NM frames and slides set new industry standards for tight tolerances, fit and finish. The brothers soon turned their manufacturing expertise and attention to detail into producing custom .223 caliber "AR" style rifles.

Today, operating out of a state-of-the-art 23,000 square foot facility in Colona, Illinois, the company is producing a full line of custom rifles, parts and accessories, all built with the same focus on providing the finest fit, finish and function at a reasonable price. The quality and reliability of Rock River Arms firearms continues to win new admirers.

Rock River Arms is one of the fastest growing firearms manufacturers in the country and remains committed to continuing to provide it's civilian, law enforcement and military customers with the kind of custom products and services on which it's reputation has been built.
