Couple of Aimpoint 3000's for the retro carbine guys, on that auction site that has an 'e' by the 'bay'.
No affiliation with sellers. I did talk to both about the sights.
One in the box the other on a .22 pistol barrel.
The guy selling the one on the barrel is willing to separate the two if it doesn't sell as a set.
I offered to buy it from him yesterday; ended up with a 5000XD instead.

The seller of the boxed unit is not sure if it works, doesn't know how to use it. I gave him a basic instructions; haven't heard back from him.
Apparently it is missing the manual. Appears to have everything else however.
