My local craft store has the sticky back , peel and stick foam. I've bought black and green ; so I know it comes in those colors . I've used it for a cheek piece pad and as a extra-grip panel on the grip areas (works good on a pistol grip too) . Not permanent, but holds up pretty good and cheap to replace. Speaking of craft foam ; get the thick sheets and cut out a small rectangle , say 2"x3" and drill small holes in them just big enough for a pellet to be force into .I use my dremel tool with a bit that I've found to be the perfect size. I drill a couple of holes in one end and run a piece of cord through it , enough to hang the pellet holder around my neck . Cheap pellet holders . You can also add some sticky back Velcro to them and add them to your gun stock , although my last time out , mine caught on something and pulled off somewhere in the woods. My original use for craft foam was/is for making foam bugs for fly fishing for warm water panfish. Lots of uses for craft foam .kirby
