What’s The Difference Between 2 MOA vs 4 MOA

Published on:

I’ve spent quite a bit of time testing both, and I’ve got some insights to share. You see, it’s not just about the size; it’s about how these dots behave in different situations. 

MOA, or Minute Of Angle, might sound technical, but it’s pretty straightforward. One MOA equals roughly one inch at 100 yards.

So, a 2 MOA dot covers two inches at that distance, and a 4 MOA dot covers four inches. In my experience, this difference is crucial. The 2 MOA offers finer precision, but the 4 MOA is easier to see, especially in a hurry.

2 MOA Red Dots

When it comes to 2 MOA red dots, models like the Holosun 407c x2 and Sig Romeo 5 have been my go-to choices. 

These sights excel in situations where hitting small targets is crucial. The 2-inch diameter dot at 100 yards offers a precise point of focus, making them ideal for situations that demand high accuracy. 

I’ve found them to be exceptionally beneficial for shotguns and handguns. In scenarios where I’m aiming at moderate distances, these sights provide the exactness needed. 

4 MOA Red Dots

Conversely, the 4 MOA red dots, like the Vortex Strike Fire II and Bushnell RXS100, present a different set of advantages. 

These sights are designed for quick engagement and excel in close-range scenarios. The larger dot size, covering four inches at 100 yards, aids in rapid target acquisition. 

When mounted on rifles or long guns, they prove invaluable in dynamic shooting situations where speed is of the essence. The broader visual presence of the dot makes it easier to locate and focus on, especially in high-pressure moments.

My Personal Experiences with Both MOA Sizes

My personal experience with both 2 MOA and 4 MOA red dots has been enlightening. With 2 MOA dots, I’ve observed the need for more focused attention and a steady hand.

 These sights are perfect for scenarios that require calm and precision. The smaller dot demands careful alignment, rewarding patience and steadiness with impressive accuracy. 

However, in more dynamic situations where targets are moving, or I need to react quickly, the 4 MOA dots shine. 

The larger dot size offers a quicker visual reference, allowing for swift target acquisition. This versatility demonstrates the importance of selecting a sight based on the specific demands of the shooting scenario.
