Primary Arms SLx Advanced Rotary Knob Microdot Red Dot Sight


This red dot sight is part of the SLx optics line. SLx optics built PA’s reputation for innovation, reliability and value. All SLx optics undergo rigorous field-testing during development to best serve you in any environment.

The Microdot, Removable Base, Advanced sight (MD-RB-AD) takes everything learned from the best selling MD-ADS microdot and refines it a step further. The Primary Arms Advanced Micro Red Dot Sight features an estimated 50,000 hours of battery life from the included CR2032 battery, powering an ultra-sharp 2 MOA dot. Fully multicoated lenses and an ultra-low profile emitter ensure a clean sight picture with minimal lens tint. Eleven brightness settings are controlled by the rotary knob on the right side. The first two settings are compatible with night vision units and cannot be seen by the naked eye. The brightest settings are daylight bright. The illumination knob physically stops at “0” with the red dot turned off.
