I have a new heavy barrel AR and I am in for a Bushnell HDMR on the Group buy. Thanks to A10XRifle for putting that together. Here is my question. I want to be able to move the scope between the AR and my bolt gun(s). From what I have read the return to zero is excellent with both the Spuhr and Aadmount. If I use a cantilevered mount, will I be able to set the scope back far enough on the bolt gun (Rem 700) for proper eye relief? If I go with a standard mount, could I set the mount far enough forward on the AR for proper eye relief? The HDMR will be the nicest glass I have had and will be the nicest for some time. I just want to maximize the use of the scope without having to change mounts/rings and waste time and ammo rezeroing. Is this even plausible? Any constructive advise is appreciated.
