Advanced Combustion GB Launcher

Hi spudfiles, I used to frequent this site with my creations but then things came up... (girlfriend, jeep, work) But now that I'm settled in after my first semester of college, I decided it was time for something new!

Specs:
84" long, 1.5" SDR 21 barrel
2" aluminum camlock
4" chamber
2" exhaust ball valve (Overkill, I know, but it's how I wanted to do it.)
Fan at back of chamber
Single spark gap provided by stun gun internals
Non-serviceable chamber (I, too, like to live dangerously. Ha!)

165 cubic inch chamber
2.75 cubic inch propane meter (3 way valve, no regulator)
Slightly over 0.8:1 c:b ratio, but still surprisingly quiet shooting golf balls.

*shoutout to starman for inspiration on paint and probably much more!
