I don't know about the Buris Fullfield II's or the Bushnell Elites,but I know about the Burris Euro-Diamand. It has the 30mm tube. Mine is a 2.5x10x44mm with the Ballistic Plex retical. I have it mount on my Remington 700xcr in 270wsm.I am really happy with it. It give plenty of light and cyrstal clear.I have heard alot ofbad mouthingon the Fullfield II.
