I recently got a new gun and scope. How do I know if I have it setup right? Should the scope be further to the front or rear? I realize I want it as low as I can get it. How do I know what is too low, if it is hitting the barrel? What is the best way for me to figure all this out? I don't really know anyone who deals with this kind of stuff. Most of my buddies act like they know, but they really don't. I will be the first to admit that I don't know squat about most of this, but I want to. I used high rings, but after reading some other posts, I would think I should switch to low? Thank you to all who reply. Any help is appreciated.
