cool gun. Is the blowgun the triger itself?

Yep, Looks like it.

This has always been my favorite bb gun because of the simplicity. Damb cool.
Although, anyone going to build one of these would be best to use a 1/4 ball valve. Alot more powerfull.

Not true. The blowgun opens much faster than a ball valve, and has half-decent air flow (not to mention its easier to shoot with the blowgun).

The magnets are Neodymium super magnets, got them from a computer hard drive (you'll have to break them apart to get smaller peices).

No, I didnt machine any of the parts, just assembled it from spare parts I'd collected over time, but if anybody is interested in making one of these still I can machine the parts now.

Thanks for all the complements guys!

Haha, A blowgun does not have better flow than a 1/4 ball valve. and if you used say, a half inch it would be great!
Blowguns tend to open pretty slow.
