I have a Bo-Mar extended sight which I took off my Model 1911 45cal pistol. It is in excellent condition and includes the mounting screws. Please see attached photos. Bo-mar is no longer in business and this sight is very rare. Please see attached photos showing sight and the gun that it came off of. I believe this gun and sight was used at Camp Perry Ohio in national matches by my uncle representing the third Naval District. I have only found one other for sale and it came with a old slide for $175. Asking $125.00 cash.
