I have one (short barrel). It's a close copy of early Brno and obviously since it's norinco the fit and finish is not up to early brno standards but better than many other nornincos.
Lots of cross over with Brno accessories like scope bases and magazine. I mounted a Leupold 4x Rimfore scope with Leupold rings and a base from Kenny, DIP ~ IIRC.
I've not shot mine past 100 yards
Shoots most ammo from very well to excellent depending on the ammo.
Aquila 60 grain 'sniper' round is really accurate out to 100. It hits the gongs at our range with authority (for a .22).
I swapped out the sling swivels for studs and can mount a bipod or a flashlight (for fighting zombie racoons and rats). The stiock pack holds extra magazine and the case (off ebay) hold extra mags (clips to some folks) and a cleanign kit with a rod.
It's taken about a 1000 rounds to smooth out the action but it's not been a hardship....
It's one of the more fun rifle to shot that I own.
