A Henry lever is one gun he will pass on to his son. It is a bit pricey but worth it. I price is an issue a Marlin 795 can be had for $150 with a scope. The Marlin is light weight and very accurate.
One more thing if he don't like the Henry you will keep it for your self.
“There are hundreds of millions of gun owners in this country, and not one of them will have an accident today. The only misuse of guns comes in environments where there are drugs, alcohol, bad parents, and undisciplined children. Period.” Ted Nugent
