Established in 1995, Rock River Arms is owned and operated by brothers Mark and Chuck Larson. Between 1981 and 1991 the Larsons worked at Springfield Armory, Inc., where Mark was the head armorer. From Springfield Armory, the Larsons went into partnership with Les Baer to form Les Baer Custom and build custom 1911 pistols. Parting ways with Les Baer in 1993, the Larsons began to build AR-15 type rifles for Eagle Arms in Coal Valley, Illinois. Shortly afterwards, they began their own venture, Tolerance Plus - later named Rock River Arms. At that time, Rock River Arms began to build AR-15 style rifles. For a time, Rock River Arms produced M1911 pattern pistols in addition to rifles, however eventually they dropped that line and now focus their production exclusively on AR-15 pattern rifles.
