I have just bought a Mil/Mil Weaver Grand slam tactical 3x10x40 scope that I installed on my DPMS 308B. I am a total newbie all around when it comes to a Mil/Mil scope from zeroing to shooting long with it. I have put a 20 moa base on it and nice rings, so the setup is there. I just need functional info. Thanks for any help because I need it!
