M1 Garand Barrel Springfield January 1945WWII Springfield January of 1945 M1 Garand Barrel. Barrel is marked " 3 S A 1 45." with very good finish on entire barrel, may be an old refinish. Has non chromed Gas Port. Bore has frost and muzzle roughness may be skewing the ME reading and reason why we made this one cheap. Barrel Muzzle Erosion (ME) gauges 1 and Throat Erosion (TE) of 4(-). Barrel is best suited for restorations as it has seen plenty of use but it is what it is, an Original WWII 1945 Barrel! Click on images for larger views of actual Barrel.
