Primary Arms Holosun HE507K-GR-X2 ACSS Vulcan Green Reflex Sight

This is the Holosun HE507K-GR-X2 built in collaboration with Primary Arms, pairing the Holosun micro reflex body with the ACSS Vulcan Dot reticle in green illumination. Green is easier for most eyes to pick up in daylight than red, which matters on a carry optic that spends its working life in whatever light the day happens to hand you.

The micro reflex footprint keeps the sight small enough for concealed carry pistols without adding bulk to the slide. Runtime is rated up to 40,000 hours on medium brightness settings, so battery changes land on a schedule rather than a surprise. The sight retains the core Holosun technologies, including the multi-reticle system and shake awake, which drops the optic into low power when the gun sits still and brings the aiming point back the instant it moves. It is a light, low profile optic that a subcompact slide can carry without changing how the gun handles.
