You are right about the break open and is why i stated it was and accura. That is the only reason i mentioned the 6" relief. Was hopeing someone with a break open would reply. I had a small relief on my cheaper Wolf and had some trouble getting my eye close to get the right sight picture. I have a MK 85 and a rolling block but the scope mounts at a different distance. Also i have to clear the hammer like the Wolf and had see thru mounts from it. Tried the same scope on the accura and not sure i like it that way. Someone stated somewhere he took the rear sights off his and used medium height mounts. The break open design is nice but presents a new challenge to mounting for me. Any accura shooters have some help for me? I liked the break open design for ease of use and cleaning from the Wolf is why i chose to buy the Accura.
