Here is the deal, I just bought a new CVA wolf. I have yet to shoot it. I really want to install a new peep sight on the rifle. It has a 24" barrel. I know I would probably have to change the height of the front sight because I am changing the location of the rear sight all the way to the back of the gun. I just don't know what height of front sight I will need. I tried calling williams gun sights but everytime they are busy. I also tried Midway USA and eabco.
