This red dot sight is part of our SLx optics line. SLx optics built our 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 we learned from our 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.
DAYLIGHT BRIGHT and Night Vision Illumination Power Setting Mode for Fixed Power Optics Red Dots provide enough magnification to enhance target identification, yet allows for seamless both-eyes-open use at close-range targets. ACSS etched reticles mounted inside these optics can be illuminated by manually dialing the rotary knob marked with numbers of increasing brightness from 1 to 11. The first three brightness settings are night vision compatible and can only be seen when the red dot is used together with a separate night vision device. The highest two settings are DAYLIGHT BRIGHT, which are bright sunlight compatible and can be seen when the 2 MOA dot is instantly acquired by the eye as a perfect circle. The DAYLIGHT BRIGHT setting is still usable even with the illumination turned off. Turning the knob until it stops in either direction will turn the red dot completely off. By dialing the setting to the right amount of illumination power, this creates a clear contrast between the reticle and your intended target, without straining the eye.
