Black Magic 'Cocker:
Ego - Stock
Milling on the outside is flawed
The first thing I noticed when I got my barrel kit (3 backs and one 14" tip) in was that it was very light. The combined weight of the 3 backs and tip felt lighter than the boomstick. Inside the barrel, it was very smooth, on par with the boomstick. The only downside was the milling on the outside of the barrel. All 3 backs were not smooth and had slight grooves on them. This was not noticeable at first, but upon closer inspection, it was hard not to miss it.
I put this barrel on my 'Cocker and had absolutely no problems. The different bore sizes meant no more balls rolling out and no more breaks. The same was true when the barrel was used on the ego. I wish I could write something about how the barrel cleans after a break, but I have yet to break a ball even after using a very poor, dimpled batch of Midnight. Accuracy was right where it should be, ball on ball.
This is a great barrel for a very reasonable price. I got my 3 backs and tip for $140 from the CP site. The only flaw was cosmetic, but it did not affect performance, so I have no complaints whatsoever. I would highly recommend the kits because once you match the paint, you don't have to worry about anything going wrong with your barrel, and you can spend more time concentrating on your game.
