Ultradot Prime XT Features The Ultradot Prime XT uses multi-coated aspherical glass measuring 25.5mm wide by 20.4mm high to deliver a bright clear edge-to-edge sight picture in a compact reflex housing. Its 6 MOA dot strikes a balance between precision and fast target acquisition making it well suited to defensive and duty applications where speed matters. Shake-wake activation automatically powers the sight on with motion and lets it sleep after two minutes of inactivity while an eight-hour auto shutoff further conserves the single CR1632 battery. With approximately 20 000 hours of battery life on a medium setting shooters can leave the Prime XT powered on for extended periods without worrying about a dead battery at a critical moment. Built on the Trijicon RMR footprint the Prime XT mounts directly to a wide range of slide cuts and plates already compatible with that industry-standard pattern. The housing is machined from A6061 aluminum and finished in flat black anodizing giving it the strength to survive a shock rating of 1 000 G along with IPX6 water resistance for use in wet or harsh conditions. Windage and elevation adjust in 1 MOA increments across a plus or minus 50 MOA range and the sight ships complete with a rubber cover mounting screws two Torx wrenches and a CR1632 battery. Weighing less than one ounce the Ultradot Prime XT offers duty-grade durability and performance in a compact RMR-compatible reflex sight for sale at GrabAGun.
