The Holosun DMS-GL6-GR-2 is a fully enclosed reflex sight engineered to mount directly onto the GLOCK Generation 6 Optic Ready System (ORS) without requiring adapter plates. Featuring a low-profile deck height that preserves co-witness with factory-height iron sights, its streamlined 7075-T6 hard-anodized aluminum housing complements the factory Gen 6 slide profile while protecting the emitter from moisture, dust, lint, and debris. Equipped with a crisp 2 MOA Green Dot reticle for high daytime visibility and rapid eye acquisition, it incorporates a forward-facing light sensor for responsive automatic brightness adjustments alongside 8 daylight and 4 night-vision manual settings. Rated IP67 waterproof and 5000G shockproof, this optic also includes Shake Awake technology with memory recall and a convenient side-loading CR1620 battery tray delivering up to 50,000 hours of battery life.
