Re: Burris Signature Zee Rings - 10 MOA or 20 MOA?
The inserts are designed to be used in sets. If you put a +10 in the bottom rear you'll need a -10 in the top rear, that and zeros in the front will get you about 10 moa.
Add a +10 in the top front and -10 in the bottom front will get you an additional 10 moa for a total of 20 moa.
Now keep in mind the inserts are in thousandths not MOA so depending on rings spacing the actual amount may vary a bit but it will generally be within a couple of moa. Most of mine have come up a little short, but not enough to matter.
Ignorance can be treated with education, sadly there is no cure for stupidity.
