WTB: Aimpoint 2000, 3000, 5000 or 9000

[Mister Donut]

Hi All,

I'm putting together a retro build, looking for a used, but functional Aimpoint red dot, either the 2000, 3000, 5000 or 9000 model.

Don't care about cosmetics, because the cheaper the better, as long as it works.

Thanks for looking!

MD
