Waffle Mags for Norinco 84S?

[sp3worker]

Has anybody used any of the Bulgarian 5.56 waffle mags in their Norinco 84S. I just got 2 today and they fit, but the bolt doesn't want to lock up without some force. I know it is because of the feed lips on the mag being to big, but I didn't want to start grinding off material yet. To anybody who has them, what part of the lips are hitting on the bolt? I can't tell on mine because the lips already had some grinding on them, so there are no rub marks. I don't want to damage these mags as K-Var already sold out of them. Any help would be appriciated.;f

This is the grinding I spoke of in the above post.

I got it figuired out. I had to file down the right feed lip (mag back towards you) a little bit to make it work. Hopefully they work when I shoot them.
