Hello

I would like to make a air powered bolt that returns by spring. I would like to know what size of pipe would fit into 1/2 inch pvc sdr (paintball size) smoothly and would slide in and out.

Thank you

Figure it out, look at clide's Semi-Auto paintball gun.

no pipe will fit in it that im aare of, you would need to lathe it down. as for the bolt design, im too damn lazy to draw something

1/8'' or 1/4'' might. Go to McMaster, and on the products, it gives you the techinal drawings.
