Holosun DMS-GL6 MRS

The Holosun DMS-GL6 MRS is an enclosed red dot built to mount directly on the Glock 17, Glock 19, and Glock 45 Gen6 Optic Ready System. It needs none of Glock's adapter plates, which takes the factory polymer ORS plate out of the mounting stack entirely. That plate has loose tolerances and no recoil fence, so removing it addresses the main weakness of the Gen6 optic interface. The DMS-GL6 sits low enough to co-witness with factory-height Glock iron sights.

The MRS model uses a titanium housing with a black titanium finish and weighs 1.48 oz. The red 650nm Multi-Reticle System switches between a 2 MOA dot, a 32 MOA circle, and the combined circle-dot. Holosun also sells green (540nm) and gold (590nm) versions. A forward-facing light sensor reads the light toward the target for automatic brightness, and the manual mode offers eight daylight and four night-vision settings. Solar Failsafe adds a secondary power source in suitable light, Shake Awake turns the dot back on with movement, and Memory Mode recalls the last reticle and brightness.

The CR1620 battery loads from a side tray, so it changes without removing the optic, and Holosun rates it at up to 50,000 hours on setting 6. Windage and elevation adjust in 1 MOA clicks with plus or minus 30 MOA of travel. The window measures 0.80 by 0.63 inches, the body measures 1.89 by 1.07 by 0.95 inches, and Holosun rates the sight IP67 with 5,000 G vibration resistance. Against the Gideon Optics Valor Mini Gen 6, the DMS-GL6 MRS is heavier and costs more, but it adds the circle-dot reticle, solar backup, and automatic brightness.
