This is my breech loaded airsoft blowgun. I put it together in about 15-20 mins, so be expecting updates in the near future(later today).
Step 1: Materials
This is what you need(Duh)
1.)Pen barell(airsoft barell for over achievers)
2.)Highlighter cap that fits snugly around pen barell
3.)Leatherman, Multi-tool, whatever you want to call it
4.)Electrical tape(any kind will work, as long as it is about a half inch wide)
6.)Mp3 player(i used mine for lighting and a stand for the vid)
