Need suggestions for a youth hunting rifle.

My 7 year old has proven that he is ready to start small game hunting with Dad. While I have been taking him for awhile now, he has just been carrying his Diana 70 and I "let him put the finishing shot on squirrels and pest birds".

The 70 fits him almost perfectly at 10" LOP, but far too underpowered for him to hunt with.

The only options for an affordable rifle that I don't mind cutting up the stock to fit him is a Discovery or possibly a Prod. Is their any other guns that are lightweight, enough power for small game at close distance, and a short LOP or atleast a stock that can be easily shortened?

I had thought about buying a disco stock to put on one of my Maximus rifles, but Crosman claims a Disco stock will not fit a Maximus. Does anyone know this to be fact or is it possible to inlet one to fit a Maximus?
 
I greatly appreciate everyone's recommendations!! I finally got ahold of someone at Crosman that assured me the Disco stock is easily fitted to the Maximus. I am still unsure how it is not a direct fit, but I don't have a disco to compare.

I ordered a Disco stock for $38 shipped directly from Crosman. Pyramyd wants over $90 for the same stock.
 
ajshootsBill, if I went with a QB, it would have to be hpa converted as co2 and our cold winters don't mix well. I actually forgot about the QB. Will have to check the hpa prices from Archers. Stocks are cheap enough to not feel bad cutting one down.

Guod, that was my plan if I go with a Prod.

I was just looking at the hpa conversion at Archer the night before you posted, for similar reasons as you. My daughter has started to show an interest in "daddies guns", but I don't have anything suitable for her to use.
