I wanted to give you guys an update. My 10 Hungarian magazines arrived. All I can say is "wow", really nice. Sorry to sound like an advertisement, but, these are really nice.
They appear to have been sanitized, no markings of any kind. They lock up nice and tight and function as well as my "Circle 10" magazines. SAM7-A1R, Yugo under-folder, SGL-21 & WASR-10 with slide-fire. What surprised me the most was how well they functioned with the slide-fire.
These magazines were supposed to be good-very good. I would rate them as almost NIB. A tiny bit of finish wear.
BTW, I paid $13.95 a piece for them. Seems a little rich until you see and use the mags. For me, it was certainly worth the price paid.
