What Are The Differences Between the Holosun 407c and 507c?

The distinguishing difference between the Holosun 407c and the 507c is in the reticle. They are both exceptional optics, but one is more versatile than the other.

Holosun 407c

The reticle on the 407c is characterized by a simple 2 MOA dot. The 2 MOA dot does a good job of balancing speed and precision. It’s easier for your eye to capture a 2 MOA dot swiftly. Yet, it’s precise enough to help you aim quickly at little targets or targets those at a close distance. 

However, the 407c comes with a red 2 MOA dot reticle or with a green reticle. You might want to consider the Holosun 407c red dot because it draws the eyes quite fast. A green dot reticle is also a great option but it is all about choice. Either way, the Holosun 407c is desirable in either a red or a green option.  

Holosun 507c

Now with the 507c, you can get 3 reticle choices that you can joggle between.

  • A 2 MOA dot
  • A circular 2 MOA dot surrounded by a 32 MOA ring
  • A 32 MOA ring without 2 MOA dot

The 2 MOA dot in this is the same as you get on the 407c. Yes, I also think it’s a good reticle for a red dot sight. However, the Circle Dot reticle is a more desirable reticle when it’s on a red dot sight. 

Furthermore, the 32 MOA ring draws your eye so aptly, but you still have that 2 MOA dot in the center to give you precision. This is a very spectacular feature in the world of miniature reflex sights. 

Lastly, we have the 32 MOA ring without a 2 MOA dot. This reticle has a Circle Dot Reticle that also gives you precision. Just like the 407c, you can get the Holosun 507c with either red reticle options or green reticle options. 

In conclusion, when it comes to the reticle, I think the 507c is superior to the 407c. With it you get the same 2 MOA that the 407c has. The 507c gets you the Circle Dot reticle and the 32 MOA ring reticle as well. Even though the 2 MOA dot reticle is good.

Frequently Asked Questions (FAQs)
