Was requested by another member to post this up here. Dan Miller is the USA rep for Excal. If you have a problem with your CB and they want to "send it in" this is the place they send it if they are in the USA. If you ever have any issues you can save your self alot of time by going straight to Dan. He also has a wealth of knowledge and has the GT Laser II's with the brass inserts in them, great arrows.
