....THe weaver style is good and the better ones are Burris Zee rings Signature style with the inserts and use either Weaver lightweight mounts or steel Grand Slam bases of steel......either will work for a 308 with good mounting of clean and locktite on the screws....the Burris are clean looking and strong and protect the scope finish.....if you perfer the "redfield" type of turn in front/windage rear the Leupold are good as any,better than some but need lapping to insure good mounting and again the Burris turn in style in Signature series have the insert style rings.....good luck and good shooting!!gunpilot said::I recently purchased a browning a-bolt hunter in .308. I like the light weight. Are weaver mounts/ rings good, or do you recommend leupold? what about aluminum vs steel for reduced weight? sniper:
