Well, It's almost Christmas break again, and it will be a year since I built the swat gun, so I figure it's time for another large scale project or two. I've got the old air chambers off the swat gun before I replaced them with 10 feet of 6 inch pipe. so, I've got 10 feet of pressure rated 4" , and 15 feet of 2 inch, since the pvc 2" barrel is not needed with the recent addition of the 20 foot aluminum barrel. I am going to make a 8 foot barreled coaxial, and a shoulder mounted coaxial rocket launcher.two much cheaper, small projects. On spudshot, Killa was throwing around ideas of making a mini swat, with a 2" or 3" piston valve. Anyone with ideas on what kinds of guns to make, feel free to post here. heck, anyone with feedback.
here's it before the new chambers
and after...
