basically, the theory is that with an ex chamber, you're giving the co2 more room to expand/evaporate and reach ambient temperature. with a remote, you're doing the same thing. instead of just the tank valve to the asa, to the gun, you've got tank valve, 3 feet of hose, then the gun.
someone please correct me if I'm wrong. The tubing just gives you more room to expand the gas. It's also a hell of a good way to keep liquid out of your gun.
Don't listen to people who say the remote will get caught on things. I used one for 3 years and never once had it catch on anything. The only hassle is shooting with your off hand.
All this being said, a good reg is better for stabilizing co2 flow.
Make it any color you want as long as that color is black.
