well there hasnt seemed to be many new guns in the bb showcase so i decided to come up with this and im surprised that it works as good as it does. it uses a burst of air to push a plunger(attached to bot) forward to hit the bb. a spring then pushes the plunger back into place

barrel:bic pen tube
casing: piece of old tent pole
plunger:pen cap with silicone face
bolt: piece of an antenna

Is this a blow forward bolt attached to a blowgun or something else?

Similar to JSR's blow forward breech, except when fired his moved the bolt forward, allowing the burst of pressurised air through. I like yours though, but do a quick search for jsr's, it's pretty good. (most things he makes are..)

yea mine is alot like JSRs but it wasnt designed to let air out. though some air does escape because its not completely air tight. and yea i think this would be considered a blow forward bolt
