My local pawnshop has a CVA Accura for sale. It has "see through" rings which I will need to replace (can't stand them). It shows some rust at the muzzle, and I have not pulled the bp to check the condition of the bore, but I am expecting some rust. They are asking $195. I am thinking about offering $115 and hoping that the bore can be restored. Since I have to buy new rings I really don't want to spend more on the gun. What do you think?
