KK all the pvc is Sch 40, I didn't show that the air chamber is end capped, and i will put a schrader on the back. so the 4 questions I have are, is there any effective way to be have an on board compressor (behind the elbow maybe), or would c02 work (how many shots off what gram?)? The next is is there any way you know of that can let you switch barrels, Because i think a .5'' would be much more suited to marbles, and maybe even nerf. do i have enough air capacity for potatoes and other heavy ammo, and will the reducing T and elbow slow the air? and lastly, will this sprinkler valve work, ive heard good things about it?

Your link only take to home page of bcarms. C02 works, the number of shots will depend on how quickly the valve seals. Your chamber is quit small, you will not get much power from a chamber that size.

Edit: your pic and link didn't work untill i submitted my post, then they came up working, wierd!

That makes more sence. As long as you stay with a small bore, say 1" and under. You will/should be able to get some nice shots off. Post video's when done, please.

as I've been browsing on mcmaster I had a question, are the threads in the valve female, cause they look sorta like they would fit bigger threads.
