Electronic Boresight Assembly (EBS)

Electronic Boresight Assembly

The Mk 43 Mod 0 EBS (Electro-optical Boresight Assembly) is a precision boresight tool utilised for accurately aligning a weapon with its sighting system. The EBS employs a state of the art colour video camera and permits a single user to accurately and remotely align the weapon to the sight from the safety of the gunner's position. The EBS provides a safe, easy to use, accurate, fast and reliable tool for boresighting that yields high first round hit probability. The easy to use EBS assembly minimizes the time required to perform boresighting and maximizes the convenience and frequency of the procedure. The EBS provides accuracy over a wide range of environmental conditions and permits weapon alignment at ranges of 10 to 2000+ metres.
