Do they make a pad/riser for the stock on a rifle?

I took my 6 yr old boy shooting this past weekend. He did okay, but can't rest his cheek on the stock and still see out the scope. So he'd try to hold his head up to see thru the scope, and still stay steady enough to shoot. I finally wadded up a sweater for him to rest his cheek on. Is there something out there you can slide on the stock to make up that gap?

Cabelas has one that is adjustable.... Go to their site and search "Beartooth Comb Raising Kit"
