New project is progress, When I think about what I made so far,
I think that the method of loading one shot and reloading is common, and this time,
I made a break action shotgun which is the best way to load those shot.
Hope you enjoy this project

What you need
8A QEV
6A slide valve
6mm tube, some one-touch valve,
I connect pipe-QEV with 8A short-threaded pipe(I don't know what actually its called. sorry

use 20A and 13A PVC pipe for barrel
stock are made by fomex(포맥스 in Korean)
power source is CO2, But it is not regulated and it is directly connected, so I have to shoot, lock, shoot and lock...
but its power is enough to me. almost 120psi/shot
It is not finished, Work is still in progress.
