First, its not a Norinco, its a NS.
Second, I have a CZ 455 Varmint. I also have a NS 522 for a year now and the CZ shoots slightly better but not by much.
The truth is with a nice stock, the NS 522 is a 500$ rifle and it will compete against any other 500$ rifle any day.
What I like about the NS >>> its way more balanced than my CZ Varmint.
You can also leave it stock and enjoy your 200$ rifle kicking asses to 400-500$ rifles.
Semantics....Norinco doesn't "make" guns anyway, they export them. Still a Chinese gun made by Chinese workers, showing all the typical Chinese QC, whether it's NS or Dominion Arms, Polytec, NSR, etc, still the same Chinese factories turning them out.
The barrels are finished pretty well, best I've seen yet from China. Everything else on the gun has the typical tool marks, roughness, sloppyness etc, sawdust quality wood,, and you have to remember these were made in the early '90s for the US market, and that was probably the peak of Chinese QC.
It's ALWAYS going to be a $200 gun regardless of how much you admire it....unless you fix all the fit and finish flaws first, there is little point to putting $300 wood on it. It will still look like #### next to a CZ...lol
I have a TOZ78 that is similar quality...rough-ish metal and action, some tool marks, mags are plastic, but a hardwood stock (beech), awesome trigger, and it shoots like a laser beam. Paid $100 NIB from Armrus when they went out of business....bought a couple of them actually.
I have a $300 Z5 that shoots tighter then my 522, and the 522 is nowhere in the same vicinity quality wise....I bet there are sub $200 Savages that also shoot as well. Not sure why you would even equate price with accuracy like "You can also leave it stock and enjoy your 200$ rifle kicking asses to 400-500$ rifles"....those higher priced rifles have higher quality components and are made in first world countries, price doesnt equate accuracy universally. Again, are you a loser if you come up short against a sub $200 Savage?
I just finished d&t on the trigger housing for a blind 6/32 over-travel screw, used some epoxy wood to bed the trigger guard so no more washers, polished some contact points on the trigger/sear, free floating and bedding the action today at some point...it's not that I don't like these guns, I have 2 of them, I just see them for what they are, a decent deal for $200 when compared to other $200 rifles.
