I have 2 NEA 7.5 rifles... both rifles have had 0 FTF's/FTE's to date but one rifle has had a few issues.
The fit on the one rifle is less than acceptable as the hole for the rear takedown pin is too big, and the original pin falls out with little or no effort.
The second issue is that the forward assist must of had some type of flaw in the metal, when I placed it on my work bench the knob and part of the pin snapped off. when I posted this on the CGN NEA forum, I was told that it had to have been my fault and NEA would not take responsibility for it. they finally sent me a new F/A (no charge).
