Something large enough to clean it after a break - I reccomend underboring with this barrel
Honestly? Hype, just like stiffi
I had one of these on a freshly tuned Ion, and let me tell you; I spent half a case of fresh paint swapping between the Ion stock barrel and this. There was NO noticable difference. The other thing is, when you break a ball, accuracy goes to nil. It actually shot worse than the stock barrel after a break. Pure hype, just like "stiffi". Don't agree? Go spend the money to buy one, you will see.
I give it an average rating because it IS light, but there really aren't any redeeming features about this barrel.
