I was talking about the part that lanches the amo




and I`m alright with the complex part of that . It would be kind`a hard to make a realistic one without it being complex.

The bazooka design is like a backwards coaxial.
The piston moves to the rear of the chamber when the QEV is open (triggered by blowgun), and the air rushes from behind, around, and over the piston.

I shoot direct fire, flat trajectory tennis balls at buildings and vehicles. Not a toy. Death can occur from a shot to the head from under 25 feet.

Chamber internal 2" pipe.

Chamber with outside tubing just before welding.

Before front barrel welded on, piston closed/charged.

When pilot is vented by QEV, the piston opens and moves back, dumping the air in the chamber.

(The piston is not installed in this photo, just trying to give a visual of what happens.)

This chamber is setup is designed for an M9 bazooka (WIP).
