New, old stock, M1A1 Combo tool for the M1 Garand or BM-59. These tools are still in grease wrap and are perfect! We have these on sale and they are a great deal! We don't know the providence of these tools, some are marked with a C inside of a diamond, some are unmarked and some may have other markings, we don't know. Because of the grease, we are not going to open them and it's luck of the draw as to which you will get. They have a 6 MM hex head where the normal rivet would be. Bill Ricca shows pictures of these on his website. He talks about how the broken shell extractor portion is cast in the opposite direction of an American type. He thinks they are 1950's Korean manufacture because the Koreans used a hex headed gas plug. I suspect they are Italian and were for the BM-59 which also used a hex design gas plug. Fit's in the butt stock and will work on any Garand. A great deal for anyone who needs one of these important tools.
