What should you do when you have exhausted the elevation on the scope and the range is longer than what the gun is zeroed for? Get a rifle scope with a higher elevation?  You have a more cost-effective option, a 20MOA Cant Mount would help.

   1. What is a 20 MOA Mount?

Most of the time shooters use a 0 MOA Mount, what is the difference between a 0MOA and a 20MOA?

• A 0 MOA mount will remain level with the barrel, it is flat.
• 20 MOA represents the cant/tilt of the scope mount, the rear of the mount is higher than the front. 

    2. What is the role of 20MOA?

Not all shooting situations require the use of a 20MOA Mount. When you have exhausted the elevation of the scope but still need for a longer range, and don’t want to change to another expensive scope, just change to a 20MOA Mount.

In short, the role of a 20MOA Mount is to make the elevation adjustment range of the scope larger to accommodate a longer range.

   3. How does the 20MOA Mount work?

Scopes have a limited range of elevation adjustment, the 20MOA Mount is angled down at the front towards the barrel, allowing for a greater range of elevation adjustment in the scope.

For many new shooters, having the front of the scope angled down doesn’t sound correct, they feel like it would make more sense to them if the front of the scope was angled up, but that’s wrong.

Let’s take a look at how it works:

While everyone has their own definition of “long range,” generally speaking, if you plan on shooting targets around 600 yards and beyond, you are considered long-range shooting, and a 20 MOA base is essential.
