If you look in the classifieds there are a few cockers going at the moment, including one I am selling
think you will find that most cockers have an inline reg that takes it down to 300-350 ( maybe up to 400 for old guns) psi
anyway, as nick sayes, cockers will run on co2, but you will need and anti-syphon bottle and again a inline reg, but most cockers come with one anyway.
air tanks dont realy matter, as long the actual pressure goin into the gun is correct so most people use a inline reg as most air systems not like goin down that low.
i'd need to know what gun and how old to tell you the actual input pressure needed
