Little man is getting more and more into skeet and trap shooting. I want to get him a good gun that he can grow with. the thing is the one's I'm looking at have completely adjustable stocks to change length of pull and cheek weld. Seeing as he lives with his mother behind the iron curtain I don't know if a shotgun with adjustable stock is legal. they're over/under guns with adjustable stock. can any1 help me out?
