I also just remove the Screws, slide the Scope off the Base's then back on again and Im right on. . In 2 Years of taking the Scope off My ACCURA for each Cleaning I have never had to adjust anything.
The Scope Mounts are Made By CVA, I bought them way back when I bought My CVA 209 Mag Hunterbolt. They have been good to me, cost only $29.00 but they No Longer make this style.
