The future is here now and its more affordable than you think. In today’s uncertain times of modern warfare, it is critical for the good guys to own the night. The problem of night time directed fire has traditionally been answered with “Starlight” image intensified night vision weapon sights. This night vision technology (which requires some ambient light to operate) has served our forces well since the 1970’s. However, Starlight night vision rifle scope do have limitations. These light amplifying scopes are extremely sensitive to external light sources like vehicle headlights, streetlights and building lighting that can cause severe distortion or blooming of images. This is a nuisance at best, but is completely unacceptable when contemplating taking that shot. This light sensitivity of these types of night vision scopes make them completely unusable in daylight or low light situations. The critical nature of weapon sighting demands solutions that remain reliable regardless of obscurants, weather conditions, and lighting. Thermal rifle scopes began to appear in the 1990’s and are a significant advantage over starlight night vision. A major issue with both types of night vision weapon sights is the need to re-zero your scope every time you switch from day optics to night optics. This is not ideal, especially in combat scenarios where it would be impractical to re-zero your weapon every day and night. The next evolution in night engagement is this clip on night vision device. These rifle scope designs use advanced optical engineering to produce a night scope that simply “clips on” in front of the soldiers day scope thus providing night fire capability without needing to re-zero. Now the pinnacle night vision scope is here- the X27 Clip On Thermal Night Vision Scope- transforms standard daytime optics into potent thermal night vision weapon sights with no need to re-zero, ever! Clip on thermal rifle scopes are the future of modern warfare and provide the good guys with a significant advantage in terms of operational capabilities, ease of use, and maintainability. The X27 is the next generation of thermal weapon sighting technology. The choice is clear for any professional involved in night time operations- the X27 is your tool of choice.
