Hey all...like a lot of other people on here i'm going to be doing some tinkering with a Norinco M14. I have been on a lot of different sites and there seems to be two different sides regarding USGI parts and new production commercial parts (7.62, SA etc). Some people say there's nothing like USGI and some say the new stuff is just as good, but I don't know enough to make up my own opinion. Wondering what same of the more experienced CGN'ers have to say on the topic? I'm going to swap out the whole gas system in a kit and the USGI is quite a bit more which just seems odd to me because it's used and refinished....??
