The company Rock River Arms, With Warranty, the Best of the Best!!! Rock River Arms is owned by the brothers Mark and Chuck Larson and is operated by them. Between 1981 and 1991, the Larsons worked at Springfield Armory, Inc., where Mark was the lead gunsmith. From Springfield Armory, the Larsons formed a partnership with Les Baer to create Les Baer Custom and produce custom 1911 caliber pistols. After parting ways with Les Baer in 1993, the Larsons began manufacturing AR-15 type rifles for Eagle Arms in Coal Valley, Illinois. Around the same time, they founded their own company, Tolerance Plus (later renamed Rock River Arms), which produced custom 1911 caliber pistols. The Larson brothers left Eagle Arms in 1997 when the company moved to Geneseo, Illinois. Around the same time, Rock River Arms began manufacturing AR-15 type rifles. Rock River Arms also produces M1911 model pistols, repeating rifles, and AR-15 style pistols in various calibers.
