Introducing the Burris RX series micro-reflex sights, meticulously engineered to be compatible with any platform designed to accept the shield rms or RMSc footprint and mounting pattern. This extensive compatibility includes popular pistols such as the glock 43, S&W Shield, sig P365 optics ready micro models, Springfield Armory Hellcat, Kimber R7 Mako and several others. Within this series, we proudly present the rxu-200 micro-reflex sight. The rxu-200 stands out as an ultra compact version, characterized by its shorter lens and chassis, resulting in an overall height of just 19.5mm compared to the RXC-200s 23.5mm height. Both reflex sights inherit the rugged design attributes that have established the RXS-250 as one-of the most resilient options available. Crafted from machined 7075-t6 billet aluminum, their sealed and impact-resistant chassis surpasses MIL-STD-810 vibration and impact standards while meeting IPX7 ingress requirements. The fully multi-coated glass lens is built to endure impacts from debris during firing cycles. Cleaning the lens with the included Burris Spudz or a similar cloth wont damage the coatings or substrate. A groundbreaking addition is the application of our revolutionary EXO barrier to the reflex sights glass. This ensures clarity even during rainy or dusty conditions, as it repels water and dust for an unobstructed view. The streamlined RX micro-reflex sights feature an always-on dot with automatic ambient brightness adjustment, ensuring optimal visibility in both bright sunlight at the range and low-light scenarios. Powered by a common CR2032 battery, their efficient RCLED technology provides an impressive 50,000 hr of runtime in indoor lighting conditions, extending further when concealed or stored in darkness. The 6 MOA red dot offers a crisp, glare-free reticle without strobe effects during movement or recoil. The chassis design incorporates a low profile base with an integral dovetail for versatile co-witnessing with most pistols, as well as a rearward slope to minimize snagging during draw and presentation. The compact RXC model boasts an expansive lens for enhanced target visibility and dot acquisition, while the ultra compact RXU model prioritizes deep concealment and reduced printing by providing a minimalist platform with minimal firearm extension.
