Laserlyte training kit - LaserLyte Bullseye Training Kit

I love using this kit it is fun and easy to use however, after only 4 times using it the laser will not go back together must have stripped the threads. I can get it to catch one thread and it works that way but for how long who knows.it needs a switch to turn it off rather than unscrewing it every time.
would have been much better to buy the blue gun with the internal laser.
the target is real good .
