I just got one of the 7600 police trade ins from J&G Sales and the gun will not feed at all. I'm fairly sure that the magazine is the culprit and think it is possibly an aftermarket mag. Sooooo..... Anybody here got a 7600 with a factory mag? I need to know what markings if any are on the mag body. Mine says 308 Win inside a rectangle on the right side. No Remington or other manufacturers marks of any kind. Also does anyone have an aftermarket mag marked like this? Thanks in advance!!!!!
