Has anybody made a coaxial with a 5in PVC chamber and a 2.5in barrel, because I can't seem to find anything that will fit in the 5in pipe to use for a piston. Would a 4in end cap work or is that still too small?
Why yes I am and I've seen it on the internet all the time and once at a hardware store, I think it was Lowes...But, the 5in pipe would be a chamber for use on a coaxial gun. The barrel that I would use is a 2.5in bore PVC.
