I had never seen or heard of these. They would not be legal for Service Rifle Competition, but they could be neat in some cases to use. I would use the M16A2 front sight in it as you then have a square post front sight. You would probably have to cut the threaded portion of the A2 sight down, but it looks like that may be all.Has anyone used one of these? Looks like a good idea, especially if you need a higher front sight .
