I bought a 20 ga. Browning Superposed with the rib disconnected about half was from the breach. I intended to send it to Art's for repair but I decided to try JB Weld first. That was about six months ago and the JB is holding. When it pops off, if it does, then I'll send it to Art's. In another case, the forend hanger broke of a 20 ga. Parker. I glued it back with JB Weld and stayed that way for about two years, including a dove shoot in Mexico. I recently had all the metal restored on tha gun and the hanger was properly soldered in the process but the JB Weld never failed. I'm not suggesting that gluing fine guns back together is the proper fix but it can be a servicable temporary fix.
