WTB: Holosun 407c-V2

I do not want to purchase any sort of Fabrique en Chine items new, but I do want to test out a setup.

Specifically looking for the 407c-V2 red dot, but if the price is right, maybe the 507c.

I was about to buy on Amazon and they went to Currently Unavailable.

Addendum, separate from the 407c-v2:

Does anyone want to offload a decent-condition Primary Arms Advanced RDS (rotary knob)/Sig Romeo5?

I’ve got a blemished PA ARDS I got for like $90 a couple years ago, something similar is what I’m looking for.
