How do you disassemble a 5906 barrel bushing?

A 5906 what? As a general rule, barrel bushings are one piece and do not disassemble. I am Sorry...: How do you "remove" a S&W 5906 barrel bushing ?? It sounds like an after market barrel of some type. The 5906 does not have a barrel bushing. The barrel is "belled". www.alpharubicon.com/leo/breakdown5906.htm This link will show you how to disassemble it.
