The first thing of note is that both the Holosun 507c and Primary Arms 507c with the ACSS Vulcan use identical housings. They have the same 507c x2 design with the same button placement, RMR footprint, and side loading 1632 battery. The main difference you'll find is the reticle.

As we showed in our 507c X2 video, the housing allows the reticle to be in auto-brightness, manual brightness, and lockout mode. You can also change the reticle design on both models by holding down the minus button.

On the standard 507c, the reticle can be the standard circle dot, only the dot, or only the circle. The ACSS Vulcan reticle can be the large outer ring with the chevron or only the chevron.

Looking closer at the reticles, the standard 507c gives you a 2 moa dot in the center with a 32moa ring along the outside. This gives you an easy-to-see reticle with the quick acquisition ring along the outside. I've used this standard Holosun reticle for some time and I found it to be extremely simple and easy to use.

The ACSS Vulcan takes a different approach and replaces the center 2 moa dot with a precision chevron. This gives you both additional accuracy and a larger target focus as less of your vision is obscured by the dot. Additionally, the chevron itself gives you additional ranging markers that can be used for longer distances.

On outer ring, the 32 moa ring of the standard 507c has been replaced by a much larger ring. Instead of being a quick acquisition ring, the outer circle actually works to bring you back to the center if you're misaligned.

In standard shooting positions, you'll likely never see the outer circle ring, particularly if you have a well-practiced draw for a red dot. But where it does shine is when you draw from more dynamic and realistic positions. Here you may be in an unfamiliar position and the outer ring gives you a quick and intuitive method to drive right back on target instantaneously.

The Primary Arms 507c ACSS Vulcan also does particularly well when paired as an offset red dot as you can choose to turn off the outer ring of the optic if it's too close to the user. Here you then have a chevron that can be used for additional distance markers instead of just a simple red dot that only marks your zeroing distance.

Using night vision, the ACSS Vulcan again shined as it gives the user a tool to find and center the pistol optic easily. With the nuances of focal distances and all the other challenges with night vision use, it's was surprising how well the ACSS Vulcan worked to easily direct the user back to the center chevron.
