I bought this optic from a member on another forum about 5 months ago. He told me he had never mounted it on a rifle and in the 5 months I have owned it it has never even been out of the box. The only reason I want to sell it is to get the EXPS 3-0. Im selling it used because the box has been opened. MSRP from Eotech is $579 I am looking to get $425 shipped for it. I can email pictures to you. Thanks.
