What do you think guys?

Don't worry guys, I have all the parts but have some questions!!!

This is the ball valve with its extensions


This is the pressure chamber i'll be using.



for this pressure chamber, how many psi will it be for its max?
And If I use a standard pipe, drill a hole in a end cap, put some o-rings and finally add a tire valve and screw it in the elbow will it be better?

This barrel i'll be using:



barrel attached to the ball valve



for the barrel is it good or If i use a standard pipe it will be better?



and finally, i'll be using plastic airsoft bb's for the projectile.

Should I put a kleenex tissue inside barrel, put the bb's inside and fire or making a piston valve is better?[/img]

wing it if the bb's fit in the barrel u have than it is fine no need for anything ( tissue or none that) and for ur pvc chamber it should say on the side
somthing like __F@ ___psi

It says 10 bar, meaning you can safely take it to 150 psi

145 psi
