When I went in for touch-up paint there was a cammo paint system. One color base and two over lay colors. It was to late for me.

For the base coat I used the stuff that sticks to plastic

A very nice looking cannon with a military-like feel to it. Very good job.

Very nice!
I noticed you have an "arm" button with the controls.
Is that for the fan?

Arm switch does the fan and feeds stun circuit.

Sarge
One of my barrels is bolt action. I got the bolt assembly from BCpneumatics. The project box only holds the stun circuit. All the wiring is under the switches.
The small video I posted shows the gb barrel I got from sgort87. I used that barrel because it had the only laser I own on it. The laser is so much fun at distances under 40ft.

Wow, 602 fps is pretty good. I love the paint job, looks very cool. The lettering on the gray box looks engraved. Good job.
