American Benjamin 422 8grm Co2 bulb,
.22 cal semi automatic? (when it works properly)
Very strange arrangement! You load all the pellets up the barrel and an arrangement of "O" rings stops the pellets all coming out at the same time, well thats the theory?
Apparently the answer to Crosmans 600 semi auto pistol.
Not very successful, not much good either, basically a collectors item.
Fitting a bulk fill Co2 adapter helps a lot!
