Stepping on soap box...Burris sig zees are only $27 at Midsouth when they have em, were on sale at Midway for $25 all month in November, I buy em on sale when I can, then I have em when I need em. Every scope I've ever mounted with em could be sold as new if they don't have some other ding or scratch put in em from use, I really like em and see no reason to use any other just to save a few $$ in ring cost. The money saved in scope value is more than enough to cover the cost of many ring sets....And if you have a misalignment problem, the offset insert kit comes to the rescue for $9, no shimming which will further damage a scope. Stepping off the soap box.... :wink:
