SH 54, I only contacted CVA Customer Service a couple of times. Once to order a new firing pin spring--mine had some rust on it so I thought I might need a spare. They sent one for free.
Another time I contacted them to order some of those little plugs that you screw into the iron sight holes after you take off the iron sights. If I remember right, they sent them free also.
I bought this CVA Optima V2 used at a pawn shop. It had not been properly cleaned(why do they do that???) but was stainless and cleaned up OK. It is more accurate then I am, if I needed another blackpowder rifle I would buy another CVA.
