. I have an American Defense Aimpoint Micro mount for sale. It has been used on a rifle for several range trips, I am switching to a fixed front sight, so I need a lower 1/3 co witness one. This is the absolute co witness model. I am looking for $80 shipped OBO. The first "I'll take it" followed by an IM or email gets it. PayPal is my preferred form of payment, and I try to ship either the day of payment or the following day at the latest. Thank you in advance.
