I just ordered the medium Burris Tactical Extreme 30mm rings from SWFA. The scope that I have on it now has a 30mm tube with a 50mm objective lens. It is atop a EGW 20 MOA with 1" high rings. With this set up the bottom of the objective is 3/4" above the barrel. If I used the 1/4" rings the scope would almost touch the barrel and I do not think I could fit lens cover on it. With the 1/2" rings this leaves me 1/4" above the barrel. I do need to mention that I have a heavy barrel with a straight taper to the muzzle.
