Hello, I just registered to see if I could get some help on the value of a .22 that was passed down to me. On the barrel it says, "O.F. Mossberg & Sons inc, North Heaven, Conn US. Chuckster AC KRO GRUV, Model 640KA 22 magnum-W.M.R." with a Weaver V22 scope. Bolt action and a clip that holds 5 .22 magnum cartridges. Please E-Mail me if you have any more questions or can give me some input on the rifle at firstname.lastname@example.org. Thanks.
