Great quality cage. Popped it in the Ultra 2 shell no problem. The one issue I have is that the center line is much lower than the center line of the original cage. I had planned to mod the stock drum for elite darts but the stock drum holes are too close to the center of the drum and won't feed into this cage properly. A custom drum is required. I ordered a 9-shot elite dart drum from Gavinfuzzy, I hope it lines up with this cage. Also, because of the lower center line, the dart path is through the very bottom of the barrel and not the center. I am not sure if this will cause a problem yet or not.
