This is a like new EOTech mount from LaRue. From their website:
Another mount designed by request. Our EO mount jacks the EO up by .275". This extra height sticks the irons low in the EO window...you can still see the irons if push-comes-to-shove. These are selling like candy. The extra height is just what the EO has been needing. The design had room for a piece-of-picatinny on the back, so we put it there and now you can mount a PVS-14 in perfect co-witness or either of the new magnifiers that EOTech and Aimpoint are coming out with.
