30mm One Piece AR Extended Picatinny Ring Mount

Feature

What are 0 MOA and 20 MOA?

0 MOA: A 0 MOA mount does not have any built-in elevation. When a scope is mounted on a 0 MOA mount, the optical axis of the scope remains parallel to the barrel of the firearm. This means that the scope's reticle is aligned with the bore axis, and no additional upward or downward adjustment is introduced.

20 MOA: A 20 MOA mount, on the other hand, has a built-in upward cant or angle of 20 MOA. When a scope is mounted on a 20 MOA mount, the optical axis of the scope is angled slightly upward relative to the bore axis. This introduces additional elevation in the scope's point of impact. The purpose of a 20 MOA mount is to provide increased elevation adjustment capability for long-range shooting or compensating for bullet drop at extended distances.
