Here it is now:

I has a firefly turret on it, with 10" barrels. The barrels are each 3" of 17/32" brass and 7" of 1/2" SCH80 PVC. It's rear loading, and the turret is manually rotated. I haven't tested ranges outside yet, but 100' ranges seem likely. It only takes 6 pumps to fill it, since I haven't plugged it (and I'm not going to).
Internals:



It has a Firefly turret and rotation mech. The rotation mech has been showed into a 1/2" PVC coupler, and bolted to a coupler that is epoxied onto the BBBB. I built a polycarb piece that holds the turret in place, and gives it a perfect seal. The polycarb piece curved around the turret towards the front is for added support.
You know how you can grab a firefly's turret and rotate it without pulling the trigger, and it clicks into place on each barrel? I utilized that to create a manual turret here. Each barrel clicks into place, and the barrels are always aligned properly.
Now for paint... I showed it to one of my friends, and they said "you need to paint that shit another color, it looks like a fucking creamsicle!" That's why I have dubbed it "the Creamsicle", and I'm going to paint the barrels white and leave everything else the way it is.

I also added an ammo holder from the firefly. It will be painted white as well.

I love this gun. It's a little front heavy, but you're naturally inclined to have your other hand holding the turret, so it's very comfortable. The accuracy and power behind each shot surprised me. It's like an air-powered Doomsayer.
I will try to put up a video (hopefully a better vid than the ones I've been posting) after I paint it.
Questions? Comments? Flames? Why have I done 3 mods in 4 days?
