Great condition EOTech 512.A65 sight.  Selling because I bought a Trijicon 4x for long range shooting.  10/10 functionality.  8.5/10 aesthetic (I'm a hard judge).  There are a few minor scrapes on the edges from storage in an overfull safe.  I purchased this site brand new from an authorized dealer in Austin, TX in 2009.  I guarantee it's not a knock off (for as long as you own it).  Since this is not a firearm, I am willing to ship after your form of payment clears.  I'd much rather sell face to face in Austin, TX.
