As a followup to the shotgun front sight installation - it fell off.
Looking at the now separate front sight, the original front bead sight was cut off the barrel flush and polished smooth. The ghost ring sight that is designed to use the front bead for mechanical strength and stability had nothing but a thin film of epoxy to secure it. The epoxy did not even fully cover the bottom of the ghost ring sight piece. No wonder it fell off.
The fix is to ship the barrel back to Wilson Combat for repair. They will reinstall the front bead, epoxy on the front sight and drill through the new front sight and bead sight and install a roll pin to reinforce the installation. Just like I requested originally.
Except for the pin installation, the manufacturers directions clearly detailed the above steps.
The sight fell off an hour before I was to take a shotgun class test. I was not able to shoot the timed and scored test. Passing with a 90% score is required to take the next class. Now, I'll have to repeat the same class. Bummer.
This issue was easily preventable with a little communication with me or by reading the included manufacturers directions.
