None so far
I have never had a real problem with side to side accuracy, but my stock setup just wasn't cutting it as far as where the paint dropped. Velocity inconsistencies resulted in some paint not flying quite as far as others and vice versa. I installed this expansion chamber and wow, what a difference! Not only was the paint having more of a constant trajectory, but the gun seemed quieter. I also really like how this chamber is larger in diameter than the stock chamber. It makes for a nice grip, while really not affecting the ballance of the gun much. One thing to be sure of is that if you are a Spyder owner like me, you WILL need a new bottomline hose. The threads on a stock Spyder hose are METRIC while the A.C.I.threads are STANDARD. I did not know this at first and tried to screw the hose in, only to have it bind after about 1/2 turn. To make this chamber work you will need either metric to standard adapter if you try to use the stock hose, or I bought a new hose all together. Turns out that the stock drop forward on my gun has STANDARD thread and the hose has METRIC at the exp. chamber end and STANDARD at the drop forward end. Seems kinda dumb. Also if you try to use the stock hose you will find that it's too long and you will need to either put a loop in the hose (I didn't really like that idea) to shorten the hose, or buy a new shorter hose with STANDARD threads at both ends. Throw on a little Teflon tape and you're good to go!
This expansion chamber is a big improvement over stock. Just be sure that you know what else you'll need to get it to work. Product performance is a hands down 10, but for the hoops that I had to jump through to get it installed I would say an 8. Don't let that stop you though, after all, you are trying to upgrade your marker, right?
10 out of 10

Yes, I would agree that a regulator probably does more in terms of consistent velocity, but may not keep liquid CO2 out of your gun. If you run a reg I would get a remote setup or anti-siphon tube installed in your tank. For me, this chamber does both those things well without the need for extra parts. I guess it all depends on where in the gun you want your $$ to go.
