The Safariland Spec Ops 33mm Red Dot Scope SOPS-33mm sighting system is the most advanced sight of this type available. This red dot scope has standard light intensity settings (1-8 manual) but this is where it leaves the rest behind; 2-night vision settings to be used with night vision equipment, and a special "Auto" feature. When putting the intensity switch on auto, the proprietary photo cell automatically adjusts the LED intensity to the ambient light in the area. This red dot sight by Safariland was built to rigid specifications so this scope can take a beating that others may not. The Safariland Spec Ops 33mm Red Dot Scope comes with two standard, low mount 33MM rings, a flash kill filter, flip up caps, one 3 volt battery, covered target turrets and heavy duty windage and elevation adjustments. Zero is maintained once set.
