I have a 512.A65 that I no longer need. This sat on my patrol carbine for past two years and has seen three classes. It does have some wear, on the front and rear edge of the hood, from sitting in the rack in my cruiser. The glass, however, is clear and perfect. I have had no issues with the sight, and it has performed flawlessly.
For full disclosure, I did have a battery leak once. I cleaned the contacts, and it has since been perfect. I have the box and all paperwork.
Asking $300 SPF
Crappy pic I know.... but you can see the reticle...
