Fx impact Barrel?

I have a Vulcan and the barrel and air cylinder are connected and it causes POI change for me. I recently got my impact and haven't really been able to shoot it much. Since the air bottle isn't coming into contact with the barrel it couldn't possibly effect POI. Ik nobody has had any issues with that at all from the little bit that I am on here. But after having a gun that does have POI issues I'm definitely a fan of free floating barrels the design is so much smarter. The impact is so much different just want to hear your thoughts.
