I just picked up an Aimpoint in a trade and it came with a black cover. It's in very good condition. I'd sell it for $25 shipped US Mail or trade it for a FDE one.
I accept discreet PP as a gift or +4% (preferred), Chase QuickPay, or USPS MO.
Email is the quickest way to get a hold of me: Brian (at) unforgiven5150 .com.
