I'll try and get a pic of my pistol setup with the adaptor in it like you guys are talkin about, with the vertical feed adaptor. I initially had mine set up like that but changed it so i could use macroline(since that's what I had on hand). I'm gonna stop by an air supply store tomorrow to get some fittings for my stuff, if they even have this type of stuff, and get my pistol up and running ASAP. I'm antsy to see how well it does. If you 2 get any crazy-cool ideas on efficiency tips, hook me up. Someone suggested a check valve on the 12 gram to keep a couple spare shots between loadings. Just to let ya know!
