I agree with "drducati" that the CZ Scout would make a fine first rifle for a young shooter. I took the liberty to borrow some info from the CZ-USA website about the rifle.
Cal; .22LR
LOP;12"
Bbl; 16.2"
OAL; 32.8"
Wt; 5#

Rifle comes with adjustable sights and a single shot adapter. Five and ten round magazines are available.

I own five of the full sized CZ 452's in.22LR and can attest to their accuracy and solid build.
