That is what they were advertised as, original military CETME 30 rounders. Florida Gun Works may be a horrible business but at least from the picture offered and the description of the magazine, it seemed like the real thing to me and not one of the cobbled-together frauds that pass for G3 30-rounders (like the kind they sell on CTD for 15 bucks.) This curved 30-round CETME mag cost 79 dollars, and I ordered it on an impulse.
I didn't know at the time that Florida Gun Works had such a horrible reputation, but they were the ONLY source I could find for this type of magazine. (And from everything I have read in the past few hours, it seems that they DO fit in an HK91.)
I'm willing to put up with a long waiting time for this magazine - it's quite rare and there may not be many more opportunities to get one like it, if there are mag capacity bans in the future. I bought it as much as a collector's item as for the functionality.
But if FGW doesn't EVER ship the mag to me, or does not respond to my emails - I'm going after them, through the Florida business bureau if I have to. Some people have reported stuff about them on "rip-off report," have talked about how they had to call their credit card companies to cancel, and some have said they've reported FGW to the Florida BBB. Well, if it turns out they've burned me, I will do everything in my power to put that company out of business.
