The grip is a large volumizer similar to the AMG cept it has no line in. The regs are supposed to be pretty easy to work on. You use a .125" allen wrench to take both regs out at the same time. To disassemble the reg, tap one end and the piston falls out. The other side of the reg will require a pick or snap ring pliers. Someone got an extra grand laying around they don't need? I'm in need of some donations here -
