IA Fog have you done something yet? The Marauder looks like the best in .22. Use a hand pump. It is designed for a PCP gun but looks a bit like a bicycle pump. It will tax you a bit until you get used to it. I use one for my marauder pistol and other PCPs with smaller tanks. The Air Force and the Impact MkII get SCUBA air.
