FAQ: FSL-0650-140

Q: How do I sight the laser in?

A: there are two screws at the bottom of the lasers that adjust the laser in an X type pattern. Loosen or tight each screw to move the dot to the desired location. For a diagram on the lasers movement please see the instructions at www.laserlyte.com/download/instructions/

Q: What size hex wrench does the adjustment screws use?

A: It takes a .035 hex wrench, if you lose yours or cannot find one please contact customer service at 928-649-3201 and we will send you a new one. 

Q: Will the FSL-0650-140 withstand recoil and stay on my weapons rail?

A: Yes, the FSL has gone under a few changes since the introduction of the laser. The two improvements are increased thread engagement on the clamping screws and cross locking bar. The increased thread engagement will give you the tightest clamp on the gun and the screws will not strip out. The cross lock bar is extra protection against sliding and matches up with your existing cross cut on your weapon.

Q: My FSL-0650-140 is flashing what can I do?

A: If the laser is flashing when activated first check to see if it has fresh batteries. When the batteries are low the laser will flash as an indicator to change the batteries. If the flashing persists after changing batteries take the supplied .035 allen wrench and tighten the two screws at the back of the laser until the flashing stops. If both of the solutions above do not stop the flashing please call customer service at 928-649-3201.

Q: My FSL-0650-140 turns on when I fire a shot what can I do?

A: If the laser is turning on during shooting the battery cap needs to be tightened. Turn the battery cap one full revolution and then test again. Continue tightening until the laser stays off during shooting.
