Have a LNIB Eotech 512 A65. Uses AA batteries. Approximately 3 hours use on the batteries.
Purchased in November and carried to the range once. Shot 30 rounds with it on the rifle and took it home. Has some marks in the slot of the mounting screw from the screwdriver but that's it.
$280.00 plus shipping to you.
Nothing wrong with it, just found that I'd prefer an Aimpoint instead.
