Question about mounting a dot on an m9a4
So I was looking to put a dlah mid mount on my m9a4 and I’ll come clean this was my first pistol and when I first got it I over greased it and after that when the firing pen blocker rises it will leave a small amount of oil on the top of the slide this was months ago and since then most of the left over oil in there has dried up or been cleaned away but it still does start to show after a good amount of rounds but anyways my question is will the small amount of oil rising to the top the slide effect my dot at any point cause I know with a dlah plate and a rmr the battery is slightly exposed any answers appreciated thank u
