The M4 is virtually brand NEW in the box, and completely free of any scratches, marks, or imperfections. Purchased from the Knesek Group a few months ago for $749. Mounted on firearm once, then switched back to ACOG.
2 MOA, and includes the original box, Aimpoint ARD, bikini lens cover, appropriate documents and manual, in addition to the QRP2 mount, which provides absolute co-witness over the iron sights.
I was holding out for a trade on a Trijicon RMR, BUT willing to sacrifice for $525 shipped.
Located in SoCal.
