Made as a collaboration between Holosun Optics and Primary Arms Optics, the illuminated HE507K with ACSS Vulcan Dot Reticle brings the revolutionary Vulcan aiming system to a micro reflex footprint. Designed for concealed carry, the HE507K is lightweight, durable, and dependable, with up to a 40,000-hour runtime on medium settings. This sight retains all the core features and technologies of the standard Holosun model, including the Multi-Reticle System, Shake Awake technology, and a built-in Lock Mode. With 12 illuminated brightness settings and intuitive push-button controls, the HE507K works in any lighting condition and is even compatible with night vision devices. This co-branded optic features the ACSS Vulcan Dot reticle system, which improves acquisition and recovery speed through its patented outer reference circle. When aimed on-target, the ACSS Vulcan Dot reticle appears as a simple, unobtrusive 3 MOA dot. When your aim is off-target, the edge of the 230 MOA outer circle guides you back to center. ACSS Vulcan Dot alleviates one of the main weaknesses of micro reflex optics, ensuring you can always find your reticle aiming point, despite the smaller optical aperture. The HE507K with ACSS Vulcan Dot Reticle features an RMSc footprint and is natively compatible with many of the most popular concealed carry pistols.

Fits and looks great on my X-Macro. Functionality is good and the side loaded battery tray is a great feature. I was hesitant about the new ACSS reticle, but it’s actually very helpful and it’s almost a natural reaction to adjust your dot back to center with it. My only complaint is that for the price point I would expect a clearer reticle, there’s a decent “star burst” on the dot but still functional.

Holosun Sight mounted easily with no problem and works well. My only two complaints would be that the battery was DOA and that the actual dot isn't the "arrow" shaped image as pictured on the side of the dot which can be used as a guide foe longer range shots.

Doesn’t come with them.. so annoying. Comes with 2 sets of other sizes. But not what you need. Haha. Ace hardware for the win.

First off, i have an astigmatism and I prefer RED optics vs green. Ive owned both and red always looks better to me. If you're on the fence about it then just get it. You won't be disappointed. I've owned several holosun optics with different reticle and the ACSS is by far my favorite.

Ok, it won't make you Rambo – but it has improved my draw to first shot and my 15yards+ shot accuracy significantly. It was waaay off zero after I mounted the optic, but was extremely easy to set on the right path. I put the 507k on my new Canik MC9, direct mount to the slide and no plates needed. Loving the pairing.

The ACSS is perfect for the Sig P365 SAS because it has no iron sights and it's easy to pick up the red dot quickly. I have two slides for the SAS, one with the bullseye recessed site and one with this optic mounted.
