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.
You can get away without a riser, but you might want one. I use a standard Leupold one piece mount when I put my Vari-X two on my M4, and it works fine - the front sight is there, but it's so close that it simply "blurs" out of the picture for all practical purposes. Sorry the pic is so small, but here's my "scoped" set up.
A man fires a rifle for many years, and he goes to war. And afterward he turns the rifle in at the armory, and he believes he's finished with the rifle. But no matter what else he might do with his hands - love a woman, build a house, change his son's diaper - his hands remember the rifle.
The front sight will disappear through the scope. A riser can go up to 1 inch taller than the flat top, and that is pretty much for cheek weld/eye-sight height as well as the objective bell clearing your rifle. I've used a scope directly on the flat top before with no issues, but that is mounted in 'tall' rings---a 40mm objective.
