I bought a rampage remote hose with side check off Ebay for my A5. The only problem is that, it won't screw into my bottom line. (My A5 is brand new.) but it will fit onto my mates whos is about a year old. Have Tippmann changed something? does anyone know if and where you can buy a new screw in bit that will fit a new A5? or where i can get a new hose with side check that WILL fit a new A5? Cheers
