I'm in the process of finishing the gun. In order to process it I must take the gun apart. It has a front sight that has a shroud surrounding it that only the blade of the front sight sticks through the top. There is no pins to punch out. I called Browning and they couldn't tell me how it comes off. They gave me 2 numbers to call but neither one of them could help. Is there anyone that can tell me how to remove the front sight?
