It is a piece of 20mm PVC, with 2 screws at the bottom with flat heads so i can glue it onto my sprinkler. Then there is 4 screws near the back, which hold the back of the laser, still allowing the front of it to move.
I then put 2 screws at the front, one for windage and one for elevation.
There are a few downsides to this, it probably wont be accurate(i dont think so anyway), you can only move the laser down or to the right, if you want up or to the left you unscrew the screw and then push the laser.
here are some pics

P.S: Credit goes to marco aswell, for throwing a couple of useful ideas at me.
