I am selling one of my Cobra sights. I believe the model is 3KN-1C, it has 14 brightness settings, 3 reticles ( 1.8 moa dot, T-reticle and T-reticle with dot ). It mounts using the standard side-rail optics mount and comes with the original box and manual ( in English ), camo carry pouch, adjustment tool, removeable sunshade and lens cleaning cloth. It is like new, I've honestly fired about 30 rounds with it and it works great. It runs on 2 AA batteries ( included ). I'm asking $165 shipped to lower 48 but will consider interesting trades, such as 30 or 40 round ak47 mags, drum mags, scout mount for AK etc. Please email me for pics, firstname.lastname@example.org. Thanks for looking!
