RE: Scope for CVA Optima
I put a Zeiss Conquest 3-9X40 mm on mine. I would think anything with a 40-ish mm bell work good as a far as height fit. My son-in-law has a Burris brand scope (Full field I think)that has a ballistic reticle that he uses to help him with bullet drop. It is also a 40 mm bell , variable (I think 3x9 also). He likes it fine.
