Excel, Gardner MA was the importer of Korean return rifles in the 80s and early 90s. As expected, some good and some dogs.
Marked on barrel just behind front sight usually on right side.
Expect a gray parkerized parts rifle with a black bolt and some type of wood (walnut, beech, birch, Korean orange crate). Check bore and expect some muzzle wear from some ROK soldier cleaning it like playing a fiddle.
excel was an importer. Military issue M1 Garands were made by six factories; Springfield Armory,Winchester,Harrington and Richardson and International Harvester Corporation in the US and Berreta and Breda in Italy.
