We have a CZ455 Scout with a Bushnell red dot on it... my 10 year old munchkin loves it.
Couple things to be aware of:
As mentioned it only comes with a single shot adapter thingee - fits my BRNO 22 mags just fine.
Does NOT come with sling swivel studs - which was a disappointment for when we went for grouse - had some installed.
The mag release is in front of the mag and if your munchkin leans up again something to shoot (tree branch, fence post, whatever) it WILL drop the mag. Stupid place for a mag release.
Wood stock is nice as an "heriloom" but for a youth gun it is a bit heavy (we just fondled the savage minimalist at the store - that is way lighter, but too big a stock for him and obviously of lower quality).
Rear site was not properly installed when we bought it - fell out first time in the field (but we went to a red dot anyway).
Super Crisp trigger. Honest 1.0 to 1.5 MOA (e.g. 1/2 an inch at 50 yards).
Would definately buy again, but would also have no problem #####ing to CZ about that stupid mag release.
