I'm fairly new to the forum, so please excuse and redirect me if this question has already been asked, I searched to no avail. I am purchasing a Bushnell ET HDMR 3.5-21x with the Horus H-59 reticle to top my LaRue Stealth Sniper System in 5.56. I'm toying with the idea of putting a 20 MOA base on the rifle from American Defense, would you find it helpful to go with the 20 MOA base? I routinly shoot out to and past 700yds with my 77g SMK hand-loads and I have found that it has fairly significant bullet drop out past 700yds. Any advice/experience would be appreciated, thanks!
