Colt Optics C-More sight in Las Vegas, Nevada For Sale

I have a lightly used Colt/C-More Tactical Red Dot Sight. CMCTACB-4 mounts to all Colt or clone M16/AR15 rifles and carbines, including the M-4, that utilize a flat top upper receiver. It fastens to the Picatinny rail with two large thumb nuts. If applicable, the Colt/CMore Tactical Red Dot Sight can replace the removable carry handle. This C More Red Dot Sight also provides a replacement A-2 style rear aperture sight. This red dot optic not only promotes extremely fast target acquisition but also allows shooting with both eyes open in an enhanced peripheral view while retaining the use of their iron sight as a back up system and for longer yardage shots.
The cheapest that I found this sight listed for sale on the internet is at Optics Planet for over $400. http://www.opticsplanet.net/c-more-tactical-red-dot-sight-for-a3-receiver-black.html
