Description
Description
This is the Holosun 509 ACSS Vulcan MOS. It is an enclosed emitter optic that uses a clamping style footprint and ships with a Glock MOS adapter plate. It will fit any double stack Glock MOS model. There is also an 509 RMR version available here.
The 509 ACSS Vulcan has a 7075 T6 Aluminum housing and the ACSS Vulcan reticle which is a 250 MOA Outer Ring and a 10 MOA Center Chevron. The outer ring acts like an "aim assist". When the Chevron is centered in the window the outer ring is not 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.
It's also an enclosed emitter design which ensures nothing will get in between the laser and the glass, giving you extra security and protection against elements like rain, water, dust, mud, snow, etc.
In addition, the 10 MOA Chevron acts like a BDC in which the bottom of the chevron is where a 9mm bullet would hit at 50 yards. Furthermore, the tip of the Chevron is the most precise aiming point possible in a pistol red dot at .5 MOA.
If you are someone who is looking for a direct mount optic for your Glock MOS Doublestack, and really like the idea of the ACSS Vulcan reticle, and also the enclosed emitter design, then this is for you.
Note: The 509 ACSS model does not share the same footprint as the 509T (non-ACSS models) and therefore is incompatible with aftermarket mounting solutions and custom cut slides for the 509T (non-ACSS models).
