Holosun HS507K-X2 ACSS Vulcan Red Dot Sight

The HS507K-X2-ACSS pairs Holosun's micro reflex housing with the Primary Arms ACSS Vulcan reticle, a thick red horseshoe wrapped around a fine center dot. The heavy outer ring pulls your eye to the sight in a hurry at close range, while the small center aiming point stays precise enough for a tighter shot. The 507K body was drawn for concealed carry, so it sits low on a subcompact or compact slide without crowding the rear sight or adding bulk to the holster.

The core Holosun technology carries over intact from the standard 507K, including the Multi-Reticle System and Shake Awake. Shake Awake wakes the emitter the moment the pistol moves and shuts it down when the gun sits still, and runtime runs up to 40,000 hours on a medium brightness setting. Nothing here needs a switch flipped before the gun comes out of the holster.
