HOUSTON, TEXAS – Primary Arms Optics introduces an all-new micro red dot sight, the MD-RB-AD, featuring a lifetime warranty and estimated 50,000 hours of battery life.

The Microdot, Removable Base, Advanced sight (MD-RB-AD) takes everything learned from our previous red dot sights and refines it a step further. MD-RB-AD 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.

Covered by the Primary Arms lifetime warranty, MD-RB-AD is designed for use on heavy recoiling firearms such as shotguns. Constructed of 6061 aluminum throughout, MD-RB-AD features 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 waterproofing O-rings until metal-to-metal contact with the scope body. When removed, the turret caps can be used to adjust windage and elevation.

MD-RB-AD comes with a removable MIL-STD-1913 Picatinny base. With the base removed, the scope body is compatible with industry standard micro mount systems, enabling MD-RB-AD to be mounted correctly on a wide variety of firearms.

Available in matte black or flat dark earth, MD-RB-AD is priced at $ 149.99.
