I’m just wondering if anyone has had any success in fitting a new tank to an Angel A.I.R. reg. I’m getting my rig back up to working order after a LONG hiatus from paintball. I know it’s big, heavy, ugly, and terribly obsolete, but I still love my Angel A.I.R. The problem is the original tank is dated back to 10/00, and with a 15 year design life I’ve had to source a new tank. I’ve gone with a Ninja SL2 77 (the lightest tank available here in the States), sourced the proper o-ring, and fitted it to the reg with no issues. However, the original tank says that it should only be used with the A.I.R. reg, so I’m a little skeptical about gassing it up with a new tank not designed specifically for the A.I.R. Any experience or insight would be greatly appreciated.
