Questions & Answers
Would a 20 MOA Mount work ok with this scope seeing that you only have only 20 MOA adjustment in each direction and need to zero this at 100 yards? Expert Answer

That really depends on the caliber of the rifle, the overall mount set up and what the rifle actually is. You would be ok with using a 20 MOA mount, but may need to adjust your zero point.
