If you look around, you can probably buy a real K98 .22 trainer for less money than the Norinco. Now if you are talking a KKW trainer then it's a different story.
However, it is a single shot and more of a curiosity than a real, usable .22.
The Norinco is a normal repeater .22 done up in a look alike mini K98 stock.
Depends what you want. If you have several .22's then buy a real Mauser. If it's going to be your only .22, the Norinco is more versatile.
And of course, the Norinco will devalue the moment you buy it and will always be a $150 gun.
The real Mauser will appreciate in value.
