I have used my 1- 8 on my MSR10 and shot some accurized AR matches with it.
Unless you are actually gonna use the 1x; I would suggest sticking to larger glass. My current optic on that gun is a 4 - 16 Vortex DBT and that is so much more useful for the application. I never once needed a 1x snap shot with a 6.5 creedmoor. I use 8 - 16x ALL the time.
