Does it's job with great efficiency, no more "snow".
Haven't found one.
It's a great expansion chamber for the money. The thing does it's job super well and you should have no problems lining it up because the entire bottom half swivels around. It looks awesome and adds some spice to the look of your gun. If you're running CO2 this will keep the velocity from dropping or rising in sudden spikes and it improves your accucary quite a bit too. The most important thing would be the efficiency, it saves you quite a bit of CO2 esepcially if you have an A-5 because the cyclone feed uses CO2 also. Unfortunately it's not a regulator but if you aren't looking to spend that amount of cash on a regulator this is probably the closest you'll get.
Great buy! I had it installed professional but if you don't use loctite at the threads instead of teflon tape, loctite works better. Also, it's very useful, it keeps your velocity at the right fps, improves accuracy, and gives you MUCH better CO2 efficiency. Buy it!
Unscrew the foregrip, unscrew the hose from the gun so all you have is the gun with the asa on the bottom. Then put teflon tape around the threads on the x-chamber and screw it into the V/A (the place the grip came off). Buy a macroline kit with whatever fittings you need to make it look best and then install one end onto the expansion chamber and the other on the asa and you're done.
If you have any more specific questions look in the forums :).
