Don't do it, get the new WGP trilogy line. For 240 shipped you can have a trilogy pro, which has a regulator and two barrel backs one .691 and one .687. I would get a JAM-like bolt first then a motorized hopper cus with the hopper you can still short stroke, I never did though but I was used to the heavy pull of a tippmann carbine. Or heres a good deal

Psychoballistics, in my experence, lacks quality. I got two delta .68 pistols from them, gased them, and since I didn't have them cocked back, which they failed to mention I needed to do in the one page manuel, the cup seals got destroyed and neither of the guns worked.
Another option you could go with is a Dragun the one
