I'm not expecting laser accuracy but a 13 inch barrel is enough for like 98% burn on 22 powders (usually) so velocity isn't an issue and the shorter barrel helps with accuracy too. The big thing is reliability. As long as it's reliable and has practical (small game inside 100m) accuracy, I'm a happy camper.
The $120 cost and 100m distance are both signs that you're very optimistic.
It should be mentioned~CZ make a model called the "Scout", which is a youth-sized, CZ452 rifle and while I've never owned one, it's supposed to be a great little rifle. If the short 22 idea is still kicking when your budget improves, maybe worth a look.
100m/"Small game inside 100m"~success with that depends on allot. Allot of practice, knowing what ammo the gun likes, knowing your hold, where your scope is zeroed, etc. I shot gophers this past summer past 170 yards with my 22, but that was a heavy-barrel CZ452 Varmint, 12x scope, bipod, custom hollow-point CCI Blazer I had ALLOT of trigger time practicing with, etc. That was just to see if it could be done, and it took over 20 shots to figure-out my elevation/windage. Average shots were 50-75 yards, lots in the 100 yard range. For the Norinco~anything past about 50-75 yards would be a stretch if you ask me, but depending on what you plan on hunting...could be done. I get pretty good accuracy with mine using CCI LR HP subsonic.
