You got 2 QEV's? or 1 QEV? becuase your large sig tells me you have STO pneumatics, which would lead me to beleave you have an STO ram, which can only use one QEV. Or are the useing TRV's? Just a question.
So, get a good inline, like the CP (COLD) or the Palmers. Or you could buy a barrel kit, Ex. Kaner, Freak, Pipe, Poision Arrow, and so on.
