Abstract
A laser small arms transmitter (SAT) includes a housing having a hollow interior and a clamp structure connected to the housing for rigidly securing the housing to a barrel of a weapon such as an M16A1 rifle. A spyglass shaped metal laser tube is rigidly mounted inside the housing. A lens is mounted in a forward segment of the laser tube and positioned in alignment with a bore in a forward side of the housing. A cylindrical laser diode can is mounted in a rearward segment of the laser tube. A circuit including a photo-optic sensor is mounted inside the housing and selectively energizes the laser diode to cause the same to emit a laser beam through the lens when a blank cartridge is fired. The rear segment of the laser tube is dimensioned and configured so that it can permanently bent to align the laser beam emitted by the laser diode with the barrel of the weapon. When the conventional sights of the M16A1 rifle are zeroed the laser beam will hit the same target reticle as a bullet fired from the rifle at a pre-determined target range.
