Oh, and an informational followup. The Stinger is apparently, in German/Austrian law, a ‘toy’. This is in part because the provided laser is not precise in windage & elevation adjustability. How do we make it precise in one aspect, and thereby precise in the other?
Note that the below all works best if you’ve already followed the included instructions, and gotten it somewhat close to where it needs to be.
Windage can be accurately adjusted from 90 or 270 degrees, and elevation from zero or 90.
The supplied laser has three equally spaced adjustment screws, 120 degrees apart.
So all we need do is align one of the laser’s adjustment screws with 90, 180, 270, or zero degrees.
To accomplish this, loosen the two mounting screws that hold the laser unit in the Stinger housing. Then turn the laser counterclockwise. This will loosen it from its switch (and luckily, that switch will retain an overall correct position for the laser). Turn it only until one of its adjustment screws aligns with true vertical (0, 180) or true horizontal (90, 270). Note that you will not have to turn it more than 1/12 of a turn to accomplish this. So your battery will remain correctly connected. Once any adjustment screw is vertical or horizontal, tighten the mounting screws.
Now then. If your alighted adjustment screw is vertical, you’ll want to sight in elevation first. Once you get there, that screw is done. From there, the other two screws control windage.
Likewise, if your aligned adjustment screw is horizontal, you’ll want to sight in your windage first. The other two screws then become your elevation controls.
