The SLx optics are the heart of our lineup. The trusted optics that have built our reputation through the years. Although many SLx optics will be familiar to Primary Arms fans, we are always pushing forward with new generations and adding even more options in response to the demands of our loyal customers.

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. 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.

Lifetime warranty

Covered by the Primary Arms lifetime warranty, this red dot sight is designed for use on heavy recoiling firearms such as shotguns and is constructed of 6061 aluminum with a Type II anodized matte black finish. Waterproofing is improved over previous models—for example, the turret caps are now aluminum instead of plastic and tighten down around the O-rings until metal-to-metal contact with the scope body. When removed, the turret caps can be used to adjust windage and elevation. It comes with a removable 1913 MIL STD Picatinny base. With the base removed, the scope body is compatible with industry standard micro mount systems, enabling The Advanced Red Dot to be mounted correctly on a wide variety of firearms.
