To redneckbmxer24,
I am not concerning ai quick change barrel system. I am concern about the human error when using the quick change barrel. When you screw in the barrel, you use a Allen wrench to secure the barrel from the sh first look of ai at video. How can you be sure that you put exactly same force/torque so the barrel is at same location every time? I would have more confident if ai supply a torque wrench or a tool to ensure the same force is applied.
This is just my clarification.
