For sale, Eotech 512 (revision F....the current one) and 3x magnifier with flip-to-side mount. Both were bought at the same time, I don't think that I have the original boxes (I don't normally save that kind of stuff). I am asking $550 for the combo. These are only for sale until this Wednesday, as I'm heading to the ranch. If they don't sell by Wednesday, I will repost them in January.
