What markings should I see on a Springfield Armory MIA National Match rifle? I have just taken one out of the box and find no markings that I expected after some experience with Match Garand rifles. Only a tang stamp. Also on the tang stamp, some digits are missing or have been polished off, so it says "M 1". Not to be suspicious, but I'd like to learn about how to quickly tell if one of these is the real McCoy. Thanks?
