I was looking into the Nikon M-223 (3-12x42SF) for my RRA Predator Pursuit AR. I currently have Midwest Industries flip up BUIS on the flat-top and front gas block. I was wondering however, if Nikon's M223 ring mount combo would clear the rear BUIS when they are flipped down. Does anyone have this M223 set-up on their AR? If so, does this system work with your BUIS.
