I bought this about two and a half years ago, tried to mount it to my AR but it wouldn't fit with the BUIS installed, so I put it away and forgot about it. I am just looking to get some money back from this puchase, so I'm selling for only $50 including shipping. If you are going to paypal me the money, if you pay via credit card, or send it as a purchase for a product rather than a gift, send and additional $5 to cover the fees. Here
is a link to Amazon selling it for $75.
Please email me if you are interested.
