For a first rifle, you're probably right to go bolt-action. That gets away from the video games/rapid fire mode that ruins good shooting. Look at your son's arm length, and start out a little longer - he'll grow into it, but don't go too big or heavy.

Scopes are hard to get used to, then they're even harder to do without. Just a basic rifle, big targets to start, lots of attention to safety, patience and praise.

Every trip to the range should be a special day, bring a picnic lunch and just spend quality time talking & plinking. These memories you're giving him are a gift that he'll be sharing with his son and grandson, just like your father and grandfather shared their memories with you.
