Hi all,
Received my SA CZ58 in 5.56 and I immediately wanted to put on the NEA parts I bought. Unfortunately, there are significant dimensional differences. Both the railed upper handguard and lower handguard from NEA had to be modified to fit my rifle. The top rail handguard is a hair too long for the retaining pin to fit. I had to mill off .8mm to get a proper fit. The same went for the lower handguard, but about 1mm needed to be shaved off from the top of the inside of retaining pin hole of the guard.
If you have an ambi safey, you will need to remove the side scope mount.
The NEIT Arms ambi/extended safety will NOT work with the supplied mags. The mags have a rib on the rear that catches on the mag release. You can jam the mag in, but getting it out requires force and removes plastic from the rear of the mag. The ambi side of the tab cannot move fully forward to release the mag properly, as it is stopped by the mag.
A little disappointing, but hopefully this gives a heads up to other CGN'ers. No fault of either Woverine, NEA or NEIT. The new receivers are slightly different from the originals it seems.
