I've shot a couple matches now with my custom stock Norinco NS522, and it seems pretty good for the job. I've shot a loaner Ruger precision with the same scope I've got on my Norinco now, as well as a loaner Vudoo in a fancy chassis, and prefer my cheap Norinco to either of them. Jerry at Mystic Precision seems to be a big believer in the little brother to my rifle, the Scorpio EM332. It's currently available new for under $200, and I just got one for my son. Have to spend a couple hours smoothing out some rough edges, do a trigger job, etc, but it feels like a totally different rifle after that. More money on the scope than the rifle is true, I spent as much or more on just the rings as I did on my rifle.
