I was seeing who has all used 40 moa on to there rife with using rails and scope mounts. If you can let me know what scope you have, what rail with what moa, and what scope mount with what moa. I have a Burris Scope XTR ii 5-25x50. I am want to get American Defense AD-RECON-S 40 moa scope mount for it. I am sure this mount will work. I also looking at there AD-RECON-SL 30 moa mount. I have 2 guns with scopes or mounts on them for now. Pictures of the guns are down below. One is remington 700 5R gen 2 6.5 creedmoor and the other is a AR10 Christensen Arms CA10-DMR 6.5 creedmoor with like a 15" rail/hand guard. At the moment I can't afford another scope, but these two mounts have levers. So i would be able to switch the scope from gun to gun real easy. I would like to stay as low as possible. Thats why i have thought about going with that 30 moa mount but it is really low and I worry about the scope objective side will hit the rail on the ar10. I am pretty sure the 40 moa mount will work on both guns but i also want to be low as possible. So does anyone think lower 30 moa will work?
