This optic is barely used, had this on a patrol rifle briefly didn't like 'donut of death' reticle due to my astigmatism. This optic is perfect for a global war on terror m4 build. Retailed new for 1200, comes with a.r.m.s ar15 flat top height optic mount. Originally was on a colt 6920. Shipping is paid for by me conus. I accept cash app only ATM
