The revolutionary patent pending ACSS Vulcan reticle provides a large circle guiding the eyes towards the 10 MOA center chevron, eliminating one of the biggest challenges for shooters new to slide mounted red dots. If you are off-center, a portion of this outer circle will appear in the window to give you instant reference on how to get centered. The circle phases out of the sight window completely when the center chevron is properly aligned in the sight window. This patent pending reticle function significantly improves sight acquisition. It takes the common frustration of hunting for the center reticle out of the equation. Don't need the circle? It can be easily deactivated to extend the battery even further.

Holosun Technologies is committed to creating innovative optic, laser/IR technologies for a broad range of shooting, hunting, law enforcement, and military needs. Using quality manufacturing standards, they provide military grade optics without the military grade price.

Unequivocally the absolute best


This is the best optic for your handguns. Now I need one on the 507k footprint.

Great for pistol


So glad I got this on preorder, absolutely love the large circle, want one for all my pistols. Fit is perfect. Comes with two packs of screws, a two way tool, mount, and even lock tight. I’m very impressed. Only thing is I found out that I have a slight astigmatism, after buying my first holosun, so I don’t see a perfect outline of their dot. It’s very slight so that didn’t deter me from buying this one. So if you don’t see a perfect triangle, it’s not the optic, it’s your eye. If you don’t believe me, use your phone, and it will look like the pictures. I highly recommend!

Quality and price


it's very good for someone with astigmatism loving it very much!<br>Very good price too! Just saving for another one......

My favorite red dot

by -

I have used red dots from the cheap $200 stuff to the Trijicon RMR and this by far is my favorite red dot thus far. I don't think I will ever buy any other red dot for a pistol. The reticle helps very much for that first "cold" draw, then muscle memory takes over on subsequent draws, for me. I didn't think I would like the chevron instead of a dot,..but I actually liked it a lot. With ammo being scarce I didn't want to shoot up a lot of ammo,...but I had a hard time putting my P320 X5 Legion down with this new Holosun on it. I highly recommend!

Great deal


Highly recommend getting the ACSS red dot.

The perfect reticle for new red dot shooters

by -

The ACSS Vulcan is, bar none, the easiest to acquire red dot reticle ever. If you are anywhere remotely close to being in alignment, the ring will guide into good alignment without even having to think about it. Just angle the gun in the direction of the portion of the ring that you see. In just a few minutes, I was automatically tracking in on the chevron like it had a homing beacon.
<br>I am officially spoiled.

Excellence in a great Red dot

A very amazing optic for the price point and the reticle makes getting on target a lot easier I would highly recommend this optic for any first-time red dot users

******* LEGIT

Look, I know I'm just making things worse by telling people how good this is but MAN is this thing good. Buy it when it's available because it will go out of stock immediately when it comes back. I want the ACSS Vulcan reticle on everything. The only thing that will make me stop buying this would be a 509T with the Vulcan reticle.
<br>The outer ring is GENIUS. Shooters who are new to red dots, people with poor presentation out of the holster, and people who might miss a dot alone will LOVE how the outer ring guides you back to the dot. No more fishing looking for that dot! Moreover for experienced red dot shooters in weird shooting positions... this circle takes you right back to the reticle! I really want another to put on a shotgun because using the ring to pattern a shotgun at 25 yards is also brilliant. I love love love this optic and carry it daily on a P365XL.



Love my HS507c-x2 vulcan
