Thread: Norinco JW15, CZ Magazine Compatibility

Hey all,
I'm looking at getting another couple of mags for the JW, and CZ are the same...apparently.
I've been talking to my local, and he has just been told that they require some gunsmithing to fit and function properly in a JW. My question is how much?
What say you wise men and ladies of this forum.
Have you been getting the genuine CZ, the knock off CZ, or could i trust the original JW spare/replacement.
It was going to be a play thing, but when it puts 5 CCI subs into 16mm at 50m, it's getting turned into a handy bike/ute/tractor gun. Just need some more reliable mags to go with it.
