This is my first bb gun, I put it together out of random bits i found in the shed because I was bored, but im pleased with the way it turned out.
It is a single shot bb pistol, the chamber is 3 inches of 15mm tube and various fittings connected to a blowgun, which is the trigger, and the barrel is 6 inches of 6mm tube sleeved with a small piece of 10mm tube which slides forward and back to open and close the breach and a 15mm thing which is just there for looks. I have it connected to a compressor at 115psi but i plan on putting a schrader on the end and using those small co2 canisters used for pumping up tires to fill it.

The gun is fairly powerful for such a small chamber and barrel (it hurts if you shoot yourself in the arm with it) and it is accurate up to around 20 feet. I plan to make some sort of mechanism so that the trigger is on the pistol grip rather than on top so that the gun can be operated one handed rather than needing two hands, and I also plan on making a small spring loaded mag above the breach so I dont have to load it by hand.

Will upload videos when i record them, so for now pictured will have to do.

Interesting "random bits" gun.
Careful with the co2 fill and that blow nozzle.

BTW, If it hurts to shoot your arm, Stop shooting your arm! :lol: 8)

Dude that looks too good to be "collected things out of the shed" it's not even rusty lol... unless ur shed is somewhat clean, because the shed i got fully dusty and cobwebby lol.

I will definately upload video tomorrow, its to late to go out now and I had to work today.

Yeah my shed is pretty dirty to but my step dad is a plumber so he has lots of old bits of pipe in the scrap shed so you occasionally find some nice shiny bits 8) yeah i didnt have an 8mm elbow so the blowgun had to go there, but i can probably build something that allows it to be pulled from the grip rather than on top
