No. Frankly I don't see a civilian need for something needed for extreme combat situations. I don't consider an AR as a SD firearm. My personal experience was situations taking 2 seconds or less and within a few feet.
Front sight only for such.
I highly recommend the Primary Arms optics. Great value for good quality and outstanding customer service.
Hope this helps you.
