ever think about taking that to school and teaching some kids a few things about pain lol. jk.

This may be a dumb question but how do you get your pump off with out letting the air vent behind the piston?

o-rinbg between the schrader ands the shock pump, which seals the connection butsn't allow the pin on the pump's female thread to physically open the swchrader's stem, meaning the schrader acts as a check valve and will be closed when the pump is removed.

Simple really, find an o'ring that is the same diameter as the valve (6mm), place this in the part that screws onto the valve.

JSRs colorful vocabulary confused me, even though im horrible on understanding things. (looks at geometry grade)

Oh come on, it's really simple - you just need to put an o-ring or similar rubber seal between the schrader and the pump connector, in such a way that the connector's pin cannot physically touch the schrader stem.

Not this particular launcher, but I did just over 1,000 feet per second with a 6mm coaxial piston launcher, and my best results were with this
burst disk pneumatic

um...........
read the posts?
he did explain...
you fill it up, then you press in the tyre valve, and it shoots.
try reading before you post, and if you already have read the posts and still cant figure it out, ask a more specific question.
