dont think the system has a name, i fill the tee with bbs and they either stay there or go down the tube. regardless of where they are in the plumbing, when i pull the trigger, they all come out at high speed

thanks, ive tried the blowgun by its self, but this has so much more power its just incomparable. also a just installed a 3litre bottle in place of the 1.5, its awsome!!

first new thread! anyway, my computer does not want to let me upload pics online so all i have is a video. the barrel is a pen tube joined to a marker casing, the air tank is 1.5litres. the thing shoots so fast that i cant capture it firing on the camera, in slow motion there arent holes in the pape...

very nice, does it use a QEV? you should add a magazine, retianing the bolt action feature of couse

nice gun, it looks like it has a barrel shroud?
ps. from that floor i'd guess your in france me to

thats a lota zip ties, lol
very clean! good work

very clean and nice

wow, nice work!!! you must have acses to some good tools!

actually I was more wondering if he had done it.

in your movie the magazine is above the barrel, could you use this system to feed ammo into the gun like in a m-16 or AR-15 setup?
also, how did you make the piston? I tried to cast a piston sorta like that one once out of hot glue, it stuck so badly that I couldn't get it out with a hammer.

Hi, I was just wondering if you added a popoff valve behind it, if you could make a magazine style BB gun,(magazine under the gun, not on top of as seen in the video)?
