Q&A: What in the Hey is MOA? Answering the FAQs on Minute of Angle

What is MOA and how do I know which one I need for my application?
In a nutshell, MOA or Minute Of Angle equals 1 inch at 100 yards, 2 inches at 200 yards, and so on.

Question 1:
Should I go with a 20 MOA over a 0 MOA? 20 MOA is a larger number and bigger is always better.

Answer 1:
Not necessarily. A 20 MOA rail is a bit taller than a 0 MOA rail, but not by much, it's only about .030" taller. Our rails are only taller in the rear to introduce the 20 MOA cant. We do not recommend purchasing a 20 MOA rail to increase the height of your scope so your objective lens clears the barrel. If you are having that issue, we recommend using higher rings.

Question 2:
Will my scope hit my barrel with the 20 MOA because of the downward cant?

Answer 2:
Typically this is not the case. If your scope is already almost touching the barrel, you may have an issue, but you would need to be extremely close already for this to be an issue.

Question 3:
Do I need different screws for my 20 MOA rail?

Answer 3:
No, we countersink the holes in our rails deeper to accommodate the same length screws across all of our rails.

Question 4:
What is the main factor in deciding if I need a 0 or 20 MOA base?

Answer 4:
The general rule of thumb that we use is, if you are shooting from 0-500 yards, we recommend a 0 MOA. If you are shooting from 500-1000 yards we recommend a 20 MOA.

Question 5:
I cant zero my rifle at 100 yards with your 20 MOA base. What is going on?

Answer 5:
We recommend zeroing your rifle at 200 yards with a 20 MOA base. Not all scopes have enough internal adjustment to zero back at 100 yards. We recommend having 60 MOA MINIMUM internal adjustment in your scope. Most scope manufacturers also do not recommend zeroing your scope in the last 10-15% of the available travel.
