Your optic will be on the free float tube/barrel shroud/rail. I don't see that as an issue, but some people (AR people) say you shouldn't have an optic on the rail over the barrel.
I put a DP Pro on the free float tube of an AR15 pistol several years ago. Zero issues with mine.
What kind/brand of optic are you looking at? A pistol sized dot or a carbine/rifle sized optic?
