For a movie I'm gonna make, I want to have a double barreled shotgun, but airsoft guns are forbidden in my country(holland sucks at some points) so I will need to make one with materials, has anybody got an idea how to make one?

Thanks in advance

Well aside from leaving your country, getting one and smuggling it back in you could probablly build one easier then most firearms.

You could find a metal working/fabricating shop and see if the couldnt build you two hinghd barrels and a mock up housing that could then be attatched to a piece of wood, carved and shapped to look like a pistol grip. The good thing is all pistol sawed off's are essentially homemade so if it looks a bit rough it still works. Good luck.

See if you can get your hands on some pipe from home depot, bring it to a welder to weld the pipes together, add a hinge in the middle to load cartridges and KEEP IN MIND AUTOMOTIVE BODY FILLER IS YOUR BEST FRIEND when it comes time to sculpting the handle. then paint, voila.
By the way, sanding is a ***** but it gets the job done.

you could also use PVC or pipe from a hardware store as the barrels if you didnt want to weld. Carving the stock out of wood, would look best, but clay or plastic are other alternatives for sure, but would feel odd and be more prone to breaking. IS there any chance that you could buy a plastic shotgun or something from a costume shop, then just cut off some of the barrel and stock? For an upcoming project I bought a cheapie plastic pirate gun and painted it up so it was useable, maybe you could do somethign similar.
