As the thread title says I need a mount. Do I mount on the receiver or the barrel for accuracy when installing the barrel each time. What is required. I’ve never shot this gun but would like to get it set up. I have a set of rings from Talley I will use and maybe even a scope or two laying around. I may also buy another scope. As a second question will I need to add some height to get out to 200 yards? I’m using 1255 FPS ammo.
