Eotech XPS2-1

I recently (May of this year) purchased a brand new Eotech XPS2-1 from an authorized dealer, but my eye astigmatism is so bad that I am now switching over to other types of optics. This version is the single 1 MOA dot version, does not have the ring. Date of manufacture is September 2013 (it was new old stock). Brand new in the original box with all the original paperwork. Asking $535 shipped.
