I have a lightly used Tacpoint 1 blue ring model if you're interested. The nasty blue writing has been removed, but it's otherwise in perfect working order, asking $120 for it. I'm selling it because I finally saved up enough to get an Aimpoint. Let me know if you're interested, they are pretty hard to find these days. Includes OEM ring and manual, and upgraded 1/3N (single Aimpoint type) battery.
Thanks for looking. Pics and questions? Feel free to e-mail me. :)
