Very nice, great detail. Color combinations are awesome. Hope you sell a ton of them.

As an update I was getting a gas leak with the pvc meter pipe and have since switched to steel pipe and brass valves for the metering pipe. Live and learn.

As MrCrawley noted one gauge is enough, I use one on the outlet of the regulator. This gives me a pressure reading and a fixed metered gas volume for setting the proper mix.

The PVC fabrication took the majority of time. With a few hours of work a week it took about 8 months to finish. Nice work on the airsoft M16. I'm puzzled by the delay in fire as well, It happens every once in a while. I'm definetly getting spark each time but it took three sparks to ignite in the v...

Test fire video added, enjoy.

Thanks guys, I'll do a little video demo hopefully in the next week or so.

Latest triumph of PVC and sleepless nights. Somewhat replica of the District 9 gas projector gun.
Basics are:
1" barrel
2" x 9" chamber
tazer ignition
internal vent fan
metered propane

All custom PVC parts

Starman - pardon my poor forum etiquette I will repost some pics to this thread soon.

Thanks for the compliments guys!

The scope is real but the accuracy just doesn't hold up with a spud and a rifled barrel. Better ammo might be prove otherwise.

It's combustion, metered propane.

I'll add some pics with details when I get a chance.

Oh, and I was born in the old country Poland_Spud...

Bahh!! he just made a modern version of this

Oooh! now just mount that on a fly wheel and spin it with a cordless drill and now we are talking.

something tells me you've got polish roots You got me, born there but raised in the states. When I was taking pictures of it outside my garage I had someone drive by stop and stare at it for a while, I was sure they were going to call the BATF or Homeland Security. I'm hoping the dayglow green trip...

Thanks for all the positive comments. I hope this week to make a video and post a link. Starman - you are right on the money, I have left the vent valve open a couple of times luckily when I shot the valve has been chest level so only my chest hair and my pride suffered the effects. I'm working on a...

This is my third spud gun. It has 3 48" long 1.5" barrels that rotate on the center shaft for quick reloads. It takes 2 people to reload but with some practice it goes pretty quickly. You can breach load the 2 barrels that are not locked in to the chamber. I used some banjo cam lock fittings to lock...
