Give the CMP Daisy 853 refurbs a serious look. Monte Carlo stock of course.
Might be a little big for the kiddo at the moment but they are a fantastic value for a great gun you can shoot in the garage. They are super accurate and come with nice peep sights.
You can shoot it too. Better yet, buy one for each of you, refinish the socks together, buy a shitload of match wadcutter pellets and proceed to have a ball.
