No It doesn't cover the dovetail, just goes around it. Its open on the top. I have the Iron sight removed on mine.
Does it cover the top dovetail? The NC Star in this video doesn't http://www.youtube.com/watch?v=Cf6KH7UaSPA
Looking for a flash suppressor that you don't see the dovetails anymore... sort of like how the one in the Nomad 10/22 works.
