EO Tech 551 A65 holosight: This is the model that takes the smaller "N" sized alkaline batteries, and has a "night vision" setting. I have one barely used pair of Duracells in the sight, and another new in wrap pair go with it. The sight is in excellent condition, used very little and works like a charm; in the original box and with the original manual.
(AR not included.
