LaserTag Airsoft Pistol Coversion

So I had some cheap airsoft pistols sitting around that would make great prototypes for some LT pistols.  They already have a good amount of space in them, and an easy to access battery compartment.

Here are the insides of a cheap $10 airsoft pistol


Here I have epoxied a lens into the slide


A made an LED holder from a wooden rod.  Then heat tubed the LED and holder.  Now it all slides inside the barrel for easy focusing adjustments.
 An example of the LED holder I made.

I was able to package the regulator and MSP in the pistol as well.
