Sightmark G-Shot Glock Black Red Dot Sight SM26070

The Sightmark G-Shot Black Red Dot Sight is an open-emitter reflex optic engineered specifically for factory, unmilled Glock slides. It eliminates the need for expensive custom gunsmithing or aftermarket adapter plates by sliding and clamping directly onto the rear of the firearm's slide. Constructed from rugged cast aluminum with an IP67 waterproof rating, it features an "always-on" 3 MOA red dot reticle that relies on a built-in light sensor to automatically adjust reticle brightness based on your environment. The sight's housing leaves ample room to retain usability of the factory rear sight while incorporating deep side serrations that double as a manual slide racker. Powered by a single, under-lens CR1632 battery, this duty-ready optic delivers up to 16,000 hours of continuous runtime across twelve 9mm and .40-caliber Glock models from Generations 3, 4, and 5.
