I found a place to get Bulgarian ak mags but they are just plain black with 7.62 at the bottom. Are these any good? It's not a waffle mag and also doesn't have circle 10 on it. Im new to AK n AR so totally blind here. Mags are in the 200-300 dollars a mag so don't want to buy junk rather get steel ones then. The Bulgarian mags is half that though.
