I've used blowguns up to 450 psi without problems, most of them can take the pressure - the problem is that they get more difficult to open the higher you go.

im working on a bolt action rifle but i cant get the bbs to stay in the 6mm barrel how should i fix this ?


Various options available.

You could sandwich an o-ring in a compression fitting:

You could also drill a hole for a small ball and hold it in place with some sort of spring:

Yes, it is a cheap and effective valve for a small bore rifle, and can be combined with a three way valve pilot if multiple shots are required.

how does the trigger system work in the qev 3way pilot valve setup,im out of my area of experience since i do simple pheumatic cannons

i need th air to burst out since it will be a high powered aisoft rifle but i am unsure of a magazine or loading system.i would like this to be semi auto but the main question is aiming
