MOUNTING/REMOVAL
MAKE SURE THAT THE FIREARM IS UNLOADED AND THE BREECH IS OPEN.
IT IS IMPERATIVE THAT SAFETY MEASURES BE EMPLOYED AT ALL TIMES WHILE
HANDLING THE FIREARM.
1. Loosen clamp screw and push it toward the housing to allow mounting clamp to open to fit rail.
2. Place the fixed portion of clamp against the rail and align the key with the selected rail groove.
3. Rotate the TLR-VIR
4. Tighten clamp screw. Verify the TLR-VIR

IR LASER SIGHT ZEROING
For a laser mounted below or to the side of the bore, there is only one distance where the bullet
path will coincide with the laser sight line. This point is the "zero range." Laser adjustment
and the muzzle velocity of the bullet determine where this point occurs. The user must decide
how high above or below the sight line the bullet can be allowed to strike and adjust the sight
accordingly. At distances less than the zero range the bullet will be above the sight line. Beyond
the zero range the bullet will be below the sight line. If mounted to the side, the bullet will also
deviate to the side of the laser line, as well as up and down. In practice, the TLR-VIR
on a handgun can be adjusted to keep the bullet strike within about 2" high and 2" low out to
about 100 feet.
There are two adjustment screws located in bushings on the body of the weapon light with 3
mrad increment markings. The windage adjustment is located on the left hand side of body.
Turn the screw clockwise to move the laser to the left (POI right). Turn the screw counter-clockwise
to move the laser to the right (POI left). The elevation adjustment is located on the underside
of the TLR-VIR
II body. With the TLR-VIR
®
ment screw will move the laser down (POI up). A counter-clockwise turn on the adjustment screw
will move the laser up (POI down). Move the laser dot in the direction that the shots are hitting
the target (example: If the bullets are striking low and right, move the laser dot down and right
to coincide with the bullet strike).
Note: When making large adjustments there may be an interaction that causes the laser to
move diagonally or bind. It may become necessary to rotate the opposing adjustment screw
counterclockwise to allow the laser cartridge to move to the desired position.
MAINTENANCE
The TLR-VIR
II clamp screw requires an application of high quality gun oil to keep it rust free.

Use a soft cloth and mild detergent to clean the glass lens and keep it free of dirt and grime.
Note: Always avoid aggressive cleaning solutions as they may damage the TLR-VIR
