Double Barrel Spud Gun Unleashes Double the Fury

By Jason Fitzpatrick on May 19th, 2011

It’s like my grand dad always said: never bring a single barrel spud gun when only a double barrel will do. If you’re in need of the double barrel goodness, this build guide can help.

The old standby in spud gun design is a simple chamber with a flammable gas inside and a basic ignition system. JC, of, mixed thing up a bit by both changing out the propellant system from an explosive gas to a pneumatic system and by introducing a second barrel. The result is a sweet spud gun that fired two projectiles independently from a primary chamber.

Watch the video above to see him testing it out with a water payload and then hit up the link below to see his schematics and build one for yourself.

If it can be modded, optimized, repurposed, or torn apart for fun he's interested (and probably already at the workbench taking it apart). You can follow him on if you'd like.
