It cannot, it is mounted inline with your barrel and should give you a point of reference, not an exact hit spot.
From what I've seen when reading the descriptions for both models, the 88089 and the 88090, the laser CAN be adjusted for windage and elevation.
After reading the instructions it says there are windage and elevation screws on the unit.
There are screws for adjustment
the expert answer is incorrect. the follow-up answers are correct. streamlight instructions identify the screws on flashlight body for zeroing the laser.
The following are instructions on adjusting the laser from this product's manual:
There are two adjustment screws located on the head of the flashlight body. The windage adjustment is located
in the deeper counter bored hole on the left side of the flashlight. Using the provided 2.0 mm Allen wrench,
turn the set screw clockwise to move the laser to the left (POI right). Turn the set screw counter-clockwise to
move the laser to the right (POI left). The elevation adjustment is located on the top of the lights (it’s in line
with the HOT symbol) body. With the ProTac Rail Mount HL-X Laser pointed down range a clockwise turn of
the adjustment screw will move the laser up (POI down). A counter-clockwise turn on the adjustment screw
will move the laser down (POI up).
yes as longg as you mounted bottom or top of the barrel, not on the side. it can be zeroed at 50 yards
