View Full Version : ProMag I.D. Question

04-16-2009, 4:29 AM
So I bought some 30rd ProMags for two different rifles/calibers. They were sent to a friend in OR. where i'm moving at the end of the year.

Two of them arrived and he wanted to try them in his guns but can't figure out which rifle they belong to (Mini-30 & AR). They don't seem to fit either and have no markings on them. How exactly do you tell them apart other than measure up the bullet?
