I had a SCBA (SCOTT) 2216 psi [AL or Steel] tank donated for me to set up for the 4H club to refill the kids air rifles. I have the refill adapter for the air arms cylinder but it is different thread than what is on the cylinder. Does anyone know what adapter I'll need or whom in Baton Rouge area may have some high pressure fittings? I don't think it is a DIN 200 like a SCUBA tank but if it is the air rifle place had those adapters. They are closed however until next week. I have my gun and a full tank of air but not the correct fitting.
