I installed this combo on my M1a. The mount used is a new version of the 4 point UTG aluminum mount. There's minimal clearance between the scope and the rail. .020 but clearance is clearance. Everything looks promising. I can't wait to get some range time ang put this scope through the numbers... Dealing with Arken was great. Ordered on line got a great discount. Items were shipped free and came priority 3Day mail.
You will be fine with that clearance for the middle portion of the scope. That setup looks really nice too, by the way!
