OK, I need opinions...(Did I really just ask for opinions?) I have a RRA Elite Car A4 Upper with a Tactical Carry Handle, built in Rear Sight and integrated picatinny rail. It also has an A2 FSB. I need to mount a Nikon M-223 1-4x20 RifleScope w/Point Blank Reticle. I have the Nikon 20 MOA Mount. Do I mount the Scope on the Tactical Carry Handle or do I take the Carry Handle off and mount directly to the flat top rail? What would you do?
