The trusted optics that have built their reputation through the years. Although many SLx optics will be familiar to Primary Arms fans, they are always pushing forward with new generations and adding even more options in response to the demands of their loyal customers. The Microdot, Removable Base, Advanced sight (MD-RB-AD) takes everything they have learned from their 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. **SPECIFICATIONS** **Battery Life:** 50000 Hours **Battery Type:** CR2032 3V Lithium Coin **Brand:** Primary Arms **Brightness:** 11 Settings **Finish:** Hardcoat Anodized **Manufacturer:** Primary Arms **Material:** 6061 Aluminum **Mount Style:** Aimpoint T1/H1 Compatible **Night Vision Compatible:** Yes **Reticle:** 2 MOA Dot **Reticle Color:** Red **Size:** Microdots **Warranty:** Lifetime **Weight:** 5.4 Oz ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
