ELEVATION KNOB
WINDAGE KNOB
ZEROING INSTRUCTIONS
1. While aiming with host weapon sights at the desired range, determine which direction(s) laser needs to
be adjusted for green dot’s position to match weapon’s point of impact (POI).
2. Make the necessary adjustments using a common tool to adjust the Windage and Elevation knobs per
instructions below, based on mounting position (from shooter’s perspective) and visible or infrared
laser dot’s relation to weapon’s point of impact (POI).
Note: Each click value for the Windage and Elevation knobs is 1 mil. If gross adjustment is required to zero the laser,
alternate between adjustment knobs while making incremental adjustments to prevent the laser module from binding.
Excessive tightening of the adjustment knobs can cause damage to the laser assembly.
If mounted at 6 o’clock position and POI is…
a. …left of point of aim, rotate Windage knob clockwise (CW).
b. …right of point of aim, rotate Windage knob counterclockwise (CCW).
c. …above point of aim, rotate Elevation knob counterclockwise (CCW).
d. …below point of aim, rotate Elevation knob clockwise (CW).
If mounted at 3 o’clock position (long guns only) and POI is…
a. …left of point of aim, rotate Elevation knob counterclockwise (CCW).
b. …right of point of aim, rotate Elevation knob clockwise (CW).
c. …above point of aim, rotate Windage knob counterclockwise (CCW).
d. …below point of aim, rotate Windage knob clockwise (CW).
If mounted at 9 o’clock position (long guns only) and POI is…
a. …left of point of aim, rotate Elevation knob clockwise (CW).
b. …right of point of aim, rotate Elevation knob counterclockwise (CCW).
c. …above point of aim, rotate Windage knob clockwise (CW).
d. …below point of aim, rotate Windage knob counterclockwise (CCW).
Note: SureFire recommends zeroing the laser sight at 25 yards, against a target, to coincide with point-of-aim of
the host weapon’s factory sights. Any discrepancy in point-of-aim (POA) versus point-of-impact (POI) at target
distances between 10 and 25 yards is negligible. Laser sight may require re-zeroing after the first 10-50 rounds,
as the adjustment apparatus may settle into position.
Laser should be zeroed every time XVL2 is reattached to host weapon.
