Knew it....Another ghetto creation from ckboy.. 10 spudbucks he never builds anything un-ghetto.. But if it's what you like doing, keep it up.

Do you use the nozzle to try get a good mixture (blowtorch)?. And also, a little tip for your darts. Forget paper, go down to a rural/farm surplus store and grab a heap of caulking cartridge nozzles (glue) for glue guns (not hot glue). Put one in your barrel, drag a sharpie round the excess and cut it off. Hole through the top, a nail and there you are..

Dude... it doesn't look ghetto at all... You asked him to use PVC pipes and he used it!... Oh oh... there is electrical tape on it... it must be ghetto!... it's not. It's probably just cheaper to use tape. Give him a break man.

I think it's great! Is that pressure rated pipe btw?

Yeah its pressure rated pipe I don't know about the plug tho. This gun will be much cooler soon I am thinking about adding a scope paint it and add a stock. It will be tight.

Not bad at all!
Your best creation so far! Keep it up!
May I introduce you to this:

These things (but then for larger diameters) will look thousand times nicer then that tape.
Otherwise, try tie-wraps.

Is your barrel secured by friction? Like simply shoving the duct-taped barrel end into the coupler?
Thats NOT safe. Get a cam-lock, union or threaded fitting. One day the barrel will blow out and you've got yourself a harpoon gun.

Trigun this looks like my other one it is just much cleaner.

Jrrdw it can shoot through 1/2 wood. I will have damage pics and a vid up soon.

psycix Yes my barrel is held in by the tape and I will fix that soon. I think that my gun bone breaker was much better than this gun.

Is anyone surprised? Anyone at all?


Didn't think so.

This "nicer one" better be freaking awesome.

not a bad build. I would be careful with the friction-held barrel, make sure to keep it clean and don't put anything on it that could act as a lubricant (if it's dirty, dry wipe it with paper towels or something). It's always fun to make small simple things like that, can't wait to see your "better one." Speaking of which, will it be pneumatic or combustion?

It will be pneumatic.
