I just bought my first AR, the S&W Mag Pul Moe sl. I bought a Nikon 3x scope and would like to mount it with QD rings. Got some high rings that are to low. How are you mounting your scopes. Is my idea of mounting QD rings a bad one. Just thinking it would be good to take it off in a hurry if something went bad with the scope. Open sights work well. Thank you.
