New semi automatic propane design

Unread postAuthor: auxiliary » Fri Jan 25, 2008 12:51 pm

The bright green things attached to the dark gray rod which is threaded moves back to close up the back only to open in the front. The rod continues into the turquoise blow forward nozzle which moves back inside the turquoise thing when the entire rod is pulled back. It does not move back far enough to where the o-ring gets out. As the propane hits the turquoise thing, it pushes it forward (chambering airsoft BB) and when it reaches a certain point, the o-ring gets out and the propane rushes through the turquoise thin and shooting the chambered BB.

I decided to attach the turquoise blow forward valve directly to the rod with the o-ring to make it more simple and get a higher rate of fire. (Somewhere like it shoots as fast as you can pull the trigger)
