MilSight HISS

Long Range Thermal Weapon Sights

The MilSight HISS S100 & S150, detachable thermal sights mount in-line with standard optical scopes (up to 15X), which serve as the eyepiece. These long range thermal sights can be detached and reattached without affecting the boresight of the day scope; significantly improving operator performance and tactical flexibility.

The MilSight S100 and S150 HISS weigh less than four pounds and will operate for over seven hours using standard CR-123A batteries. HISS has been successfully tested on weapons up to and including .50 caliber rifles.
