I'll sell you a black MBUS for $50 shipped, it's a never used take off from Colt 6920 (I decided to go with a fixed rear sight).
PHX223 Thanks for the offer. I am unsure what I am gonna do. I have an issue with my eyesight that may preclude a peep type rear sight. After two cataract surgeries I and quite far sighted and I am not sure how to deal with that with rifle sights. I am thinking some sort of optics may work better but I just dont know. I want to go to a show with a few optics vendors to see what is out there so i can have a better feel.
