laser pointers

[JnK]

where can I purchase, or have made, a lightweight laser pointer that I can turn on and off by remote control.
I am a target shooting coach and would like to fix a pointer to the barrel of a rifle when it is on the target area, I do not want the pointer distracting others or worse pointing out of the target area.

You could take any laser pointer and super glue the switch so it stays on all the time.
Then solder two wires in series with the batteries so it only turn on when the two wires are crossed. Then tie the two wires to a relay remote like this:

Alternative, look in a gun magazine for one to buy. I'm sure someone already makes them
