Night vision compatible, the Carbon Fiber M-Spec co-witnesses with night vision devices and select magnifiers. An advanced, true color anti-reflective lens coating improves low light performance and helps with night vision compatibility as well. The sight’s unique motion sensing auto-on feature automatically shuts the M-Spec off if it sits motionless for more than 5 minutes. Ideal for use on AR15s and MSRs, the Ultra Shot M-Spec Carbon Fiber is equipped with unlimited eye relief and a parallax-corrected optical lens system, allowing shooters to sight accurately from 10 yards to infinity. Built to adapt to any environment thrown its way, this reflex sight offers 1,000 hours of battery life off a single CR2 battery. The Carbon Fiber M-Spec FMS includes neoprene cover, adjustment tools, battery and manual.
