Description

The Holosun 507K X2 ACSS Vulcan is an open reflex pistol red dot with a modified RMSc footprint a.k.a. K Series footprint. It is intended for use on subcompact and micro compact pistols. 

It will fit on a K series slide directly (like on the Sig P365) but will require an adapter plate to fit on RMSc slides (like the Glock 43X MOS).

The 507K X2 ACSS Vulcan features a 230 MOA Dotted Outer Ring and a 3 MOA Center Dot. The outer ring acts like an "aim assist". When the dot is centered in the window the outer ring is barely visible. But if you have difficulty "finding the dot" you will see the large outer ring. This will tell you how to adjust your grip to "find the dot".

If you are new to red dot pistol shooting or shoot in competitions the ACSS Vulcan reticle is truly a game changer.

Whether you are new to shooting pistol red dots or want a competitive edge during competitions, the 507K X2 ACSS Vulcan with it's amazing and innovative reticle will make you faster and more accurate.

507k x2-acss

So far an awesome dot. I did however have the battery screw come loose while shooting and have the screw, the battery and the door go flying at an outdoor shooting area. Spent 40 minutes trying to locate the parts. Didn’t locate all of them. Check the tightness of the battery screw better yet put some blue lock-tite on it.

Great optics.

Optics were great along with your service

Works well

Having the correct screw length is important and if the screws are too long they can cause malfunctions in your firearm. I just ran 100 rounds through my equalizer with he 507k using these screws and had no issues.
