Hello everyone!

This is my 6mm BB gun that is composed of a blow gun, bike pump adapter and a barrel made out of 2 pen tubes. The footage was recorded during the summer, but I totally forgot to upload this project.

I built it in this way to save parts and to easily convert my regular ball valve airgun to a BB gun. Bike pump adapter was attached to this blow gun with electrical tape and some soft wire. Despite its appearance, its sturdy and 100 percent leak free.
Technically, using this kit you can convert any air gun to a BB gun if it has a Schrader valve as air intake. With this reservoir I was able to get 2 or 3 decent shots. It was pressurized to about 80 PSI.

Below are some photos of it and a YouTube video of it in action, plus you can see my ball valve airgun and a slow motion segment in which some rocks are fired as buckshot basically. Enjoy the video!
