I have a like-new Eotech 512 holosight, in box, for sale. It has been mounted, about 20 rounds fired, and removed. Works perfectly, I just prefer my Aimpoint.
This is Rev E, I believe (does not have the new style buttons).
Asking $265. Email me at waveman1978ATaol.com (replace "AT" with the "@" symbol)
Sorry, no pics, I don't have a digital camera.
