New Norinco JW 15 modifications

I really don't know if thois is the right forum, but here it goes:

I have a brand new JW 15 Norinco that I bought because a, I learned to shoot on a Brno #2 that my dad had way back in the 70's, and b, I can't afford a Brno or CZ, and C, the JW15 is supposed to be a knock-off of the Brno. Simple economics.

I keep hearing that there are modifications that can be made to this little .22 that are supposed to make it "pop". any suggestions out there?

For starters, where (if anywhere) can a guy get a decent stock for it? I have the black plastic one. Any suggestions for "cleaning her up"? Already cleaned out that bunker crude the Chinese seem to ship everything in.

They are a nice little rifle, very accurate.
I am not a fan of plastic, my wifes is on wood, she does pretty well in comps. with it, she has pushed my trophies off the mantlepiece.

Have you checked SARCO or Numrich? I saw new wood stocks at one of the two for about $20.
