I am currently waiting for my first PCP rifle to arrive. I plan on buying an SCBA tank to air up the gun. My question is, what kind of set up are you using from bottle to gun? Should I buy one like the Stikman or the one from AirTanksForSale, or the Chinese made off of Ebay? Or should I try to build my own. I watched a video on Youtube of the process, I would just have to acquire the parts. Is it necessary to have a regulator on this setup, or just run a hose with a fitting on each end and watch the fill gauge on the gun? Any help with or without pictures would be helpful. Thanks.
