2 years ago I took my then 8 yo daughter who at the time was 4'2" and about 75lbs to the range to shoot her new Marlin 60 and if she wanted my M&P AR-15. I took along my XD .40 and my wife's Sig Mosquito (yes, it's the pink one). She had been versed for over a year ad nauseum while starting her out on a Crossman pump master BB gun concerning gun safety, proper breathing techniques, muzzle location and trigger control to the range for some fun plinking. When she got to shooting the Mosquito she was VERY accurate and LOVED everything about it. It was a little big for her but she compensated by bench resting it on a sand bag. I'm sure now that she is almost 6" taller and about 15lbs heavier it would be much more easily handled with or without the rest. They're relatively inexpensive, pretty darn accurate, they have one in all black and it's shooter friendly once you get past the finicky break in period.
Just another suggestion but I'm sure whatever he gets he will have a lot of fun hanging with his Dad making amazing memories that will last a lifetime.
