Atn X site 4K PRO 5-20 on Larue quick detach return to zero mounts. The pro comes with the standard IR Illuminator but I have the IL850 Supernova with adjustable mount as well. Once you get the corona of the IR centered these things are crazy good. Like new condition. Retail scope is $799. Mounts are $400 and the supernova is another $200. Sell for $850
