MC58: A USMC Semiauto Trainer 22 for the M14
The H&R MC58 is a specialized .22 LR semi-automatic trainer rifle developed for the USMC to replicate the handling characteristics of the M1 Garand and later the M14. Based on Eugene Reising's submachine gun design, it features a unique charging handle and safety placement to mimic its service rifle counterparts. Approximately 3,500 MC58s were produced, with many later sold as surplus.
