In this short Q/A guide, let's break down the difference between 65 and 68 MOA ring reticles.
Are they really that different?
Here is the deal:
65 VS 68 MOA Major Difference
There is NO difference!
If you just look at the specs on paper, it looks like:
68 MOA is for a standard 5'8" tall human size target, and 65 MOA is for a 5'5" tall human based on just looking at the number.
But its actually:
- 68 MOA is the outer ring diameter
- 65 MOA is the inner ring diameter
So the reticles are the same.
Holosun markets as 65 MOA, and EOTech markets as 68 MOA. Not sure why but they are the same size with slight difference on the hash marks
How did we figure this out?
There aren't any helpful answers on the internet, so we reached out to EOTech directly for some clarification, and here is the answer we got:
68 MOA Reticle Applications
The 68 MOA ring reticle is designed for fast target acquisition and range estimation. Works extremely well for CQB type applications.
Simply just place a target in the center of the ring and engage.
The center 1 MOA dot provides a precise aiming point and the 68 MOA ring around it serves as reference points for holdover and target distance estimation on a known human size target (5'8" ~ 68" tall).
Depend on how you zero this reticle, the ring can serve other holdover purposes based on your specific applications.

In addition, the 68 MOA ring can be used to represent shotgun pattern (Based on shell and choke selection)
For example: A 36 yard zero makes the bottom of a 68 MOA ring the point of aim & point of impact at 7 yards for CQB shooting.
How Does The 68 MOA Ring Range Estimation Work?
The 68 MOA ring is very simple to use.
The center 1 MOA dot is just like any other dots out there to help you aim, and the ring helps estimate distance simply by placing it within the ring.
See example below:
EOTech's recent EXPS line of holographic sights has built-in bullet drop compensators, and each model has its own specific BDC designation for various ranges.
If you are buying one and you might see something on the box like: EXPS2-0 or EXPS2-3...etc
- -0 [1 MOA dot]
- -2 [2 BDC dots]
- -4 [4 BDC dots]
