Homemade burst fire/full auto BB pistol.
Posted: Wed Nov 24, 2010 8:39 am
Around four years ago I posted a how to topic on a site called Rotteneggs.com about an airsoft BB gun that was capable of burst and rapid fire.
This is a rather out dated version, but the design is exactly the same.

Take a look at the profile to see a validation of my Spudfiles name.
Over the time I have created many new models, but this one would have to be my favourite.
It is capable of propelling a 4.5 mm steel BB around 80 to 100 metres in roughly a second.
This here is the inside, the PVC tube fits snugly around the screw on washer that is supplied with the gas bike pump. If you are interested in building this gun, click on my other Photobucket gallery for step by step instructions on how to make this part, which is the most important part of the gun.
This is the rubber tubing, reinforced with some very strong clear tape, with some special tape string. It connects to a thicker tube and the barrel.
This is the screw on washer which actually came with the gas bike pump. Also you see a wall of tape that I wrapped around the tube. This plugs the thick tube inside the gun. It should also be thick enough to fit snugly inside the muzzle of the Gas bike pump. The washer is then screwed onto the muzzle threading.
This is what the gas bike pump will look like once you take the covering off.
This is the model of gas bike pump that I got. They are around 56 dollars AUS. Notice the covering.
This is what the gas bike pump should look like when all of the “stuff” inside the muzzle is taken out.
This here is the screw on washer that is supplied. It is responsible for keeping the handle, the PVC tube, and the barrel/tube in place.
The handle is basically tied to the PVC pipe using zip ties with the help of five holes that I drilled out. The top tube was cut from a broken carbon arrow that I use as a basic sight.
Now, for the terrible quality video.
Tell me what you think!
