Bad deal. Will not deal with again. Sold me a real Eotech, but also a fake Eotech 4X magnifier a few months ago. Unfortunately, I found out several months later when I went to re-sell the magnifier. I am not posting this lightly, I have researched indicators of fake Eotech magnifiers extensively. I contacted kevin40_2001 by PM weeks ago and got no reply. Called him and texted and he replied, but to date has not really attempted to rectify the situation. If anyone wants proof, I've got saved PM's where I asked prior to the sale and was told these were "the real deal".
