A empire reg is exactly the same as CP internally, I believe CP actually makes it for them. I am pretty sure hybrid is also pretty close in design if not the same.
AKA makes the best regs, they have the highest flow and are the most consistant. The 2 liter is the best although a sidewinder is not far behind in performance and its cheaper.
I have owned both multiple times and will say the sidewinder is more comfy and usually looks better on guns, sometimes the 2 liter won't even physically fit on the gun (example I tried one on my old cocker with ego frame and you would of had to take the frame off everytime to get the reg)
Back to gun whoring.....
