Bought this on sale with a rebate as well which made it ultra inexpensive. I have another one on my other .22 and I love it. My issue was that one of the rings for this one was defectively manufactured and wouldn't allow it to mount on my gun. I spent the next 8 weeks trying to get a replacement ring. The manufacturer was always nice and wanted to handle it properly but kept losing the shipment somehow. I finally do have the replacement though.
