Hey guys, could anyone with a good knowledge of SP M40A1's help me out here ...

I need to find a spring the correct diameter to fit the PDI spring guide, also I need to find a cylinder for a spring set up.
I can run it on a gas set up, but I have the PDI spring guide, PDI vaccum piston x2 and a tapered cylinder head and would like to be able to use these.

All the best guys, and thankyou for taking the time to help!
