For those of us that still believe in the necesity of iron sights as part of our rifle (and not a removable "option") but still want the ability to use all the bells and whistles (ie. optics, N.V., Lasers, Lights, etc.... ). The AR carry handle mount I ordered really fills the bill. If my Optics get taken out I can either use the see-thru option or quickly and easily remove it. It's well made and bargain priced.
