I have a Bushy M4A3 and a 3x9x40 scope. What I don't have is a mount. Will mounting the scope directly on the flat-top rail give me a problem seeing the front sight in the scope? Should I get a riser?
If you have photos of your set-ups, I'd like some examples.
PS. I am not looking for a red-dot, I want the AR for 100-250yd range. Oh, and I want something relatively inexpensive.
