This is an exceptional, as-issued example of a Harrington & Richardson MC-58 .22 caliber semi-automatic training rifle with U.S. Marine Corp property markings. The MC-58 was an H&R Model 65 with parkerized finish, and an M14 style safety and front sight. The rifle has a Redfield micrometer rear sight, 10-round detachable magazine, military style sling swivels on the stock and forearm and a military style oil-finished walnut pistol grip stock. The top of the receiver is marked "USMC PROPERTY, MODEL MC-58/H&R MODEL #65 MODIFIED/HARRINGTON & RICHARDSON, INC.". The top rear of the barrel is marked "= USMC PROPERTY =/HARRINGTON & RICHARDSON INC./WORCESTER, MASS., U.S.A." and ".22 CAL. LONG RIFLE ONLY" on the left rear of the barrel. The serial number is stamped on the left side of the receiver in front of the rear sight. A small, "Three Star/Eagle" National Defense Inspection final inspection mark is stamped on the inside of the pistol grip. The Marine Corps purchased a small quantity of MC-58 rifles in the late 1950s. The MC-58 is a scarce .22 caliber military training rifle. A U.S. Department of the Interior, Sport Fisheries and Wildlife inventory sticker is affixed to the inner forearm.

Excellent plus as issued, retaining 99% plus original parkerized finish with some handling marks. Stock is also excellent plus with minor wear and handling marks. Mechanically excellent.
