Question for you more experienced shooters out there. I am going to get the new Arken 4-16 and split time with it between a 6.5 Grendel upper and 556 SPR upper. Because of moving between uppers I want my mount to be QD, but I'm wondering if I'll also need it to be a 20 MOA mount too? From what I understand the Arken has 36 mils of travel, is that enough travel to justify 20 moa? I will for sure be shooting from 100-600 yards with both, but may occasionally try and go beyond 600 with the Grendel. What do you guys think? Worth the extra money getting a 20 moa mount or not worth my time?
