MC58: A USMC Semiauto Trainer 22 for the M14
This video delves into the MC58, a USMC semi-automatic trainer chambered in .22 rimfire, designed to mimic the handling of the M14 rifle. Introduced in 1958, it's a successor to the earlier Model 65 trainer based on the M1 Garand. Key changes include an M1/M14 style safety. The description highlights the rifle's history with the US Marine Corps, its development by Harrington & Richardson, and its commercial market attempts. Approximately 3500 MC-58s were purchased by the USMC.
