I have a Norinco jw15a-13.
It's a really nice "basic" rifle. Rough and ready in its finish but actually a very decent little gun.
Mine arrived utterly slathered in grease - it came in a plastic bag and looked like it someone had poured about a quarter pint of very thick engine oil in it and shook the bag. Downside is that it took 45 mins in a sink of hot water to get the gun usable, Upside was that the gun was totally corrosion free.

Tip - soak the bolt in a small tub of mineral spirit (turpentine substitute) for a few minutes to help degrease then oil it up again with light gun oil before use - mine was leaking thick goop for weeks until I finally did this.
The crown on mine was similarly bare steel - it really looked like they had cut down a full sized barrel and then smoothed it on a lathe. Overall though the synthetic stock was good and the quality of the machining was OK.
As far as shooting goes, the bolt action is rough, it took me a few hundred shots to get it working smoothly. You really need to be assertive with it. I found that some cartridges dont load too smoothly from the magazine and can get stuck with the bullet hitting the lip of the chamber and deforming. Copper plate rounds seems to work the best.
The magazine is all metal and seems robust. Potentially substitutable with the cz magazines - but they are $50 each

and for a $200 cost rifle that's a lot.
The really weak point with this gun though is the open sights. The front sight is a monster - huge - and far too fat to be effective. As a fat black sight with a black rear sight getting a proper sight picture is miserable. You read on the internet about people who file down the front sight or using a triangular file to widen the rear sight. Neither option is really optimal.
I actually bought a red dot sight to put on the gun - the iron sights were that bad. For me this is a huge weakness. I wanted an ultra portable compact rifle - and strapping a scope on the top sorts of kills that.
With the scope it shoots really well. Acceptably tight grouping @ 50 yds that are limited more by my skill than the rifle.
My only other real niggle with the gun is that the on bolt safety does not work as described in the manual. This seems to have changed with versions so you may need to push up not down as described.
In conclusion I'm glad I bought it - the price was right and its certainly a fun gun to shoot. However it is appropriately prices rather than being a bargain - for $200 you get a $200 gun, not more nor less, so set your expectations accordingly. If I was handier with the gunsmithing and could do something about the sights then it would be an outstanding purchase, but, as is, it's solidly OK.
