I'm not fond of the Anson style forend latch, but that's how they make these. Gun in question is a "B. Rizzini Upland EL Side by Side". The current model number is 550/552, I do not know if they use the exact same forend system.

Anyway, mine fell off. Not the forend, just the button that you push to unlatch it. I went to push the button, and no button. Gun won't come apart with no button.

I was fortunate to find it on the skeet field. Visions of $$$ floating in head. Had this happened in the woods... doomed.

Good news is... the whole piece somehow unthreaded itself from the forend iron. It's not actually broken. I have no idea how it could have made as many revs as it did undetected, but it did. I simply threaded it back in, good to go. Locktite job pending.

Suggestion: If you have a Rizzini, try to turn the latch button (with the forend off the gun). If it turns easily, you may want to Locktite it in. I do not know if this applies to their O/U guns but I highly suspect it does.

I seem to recall that when I was working in the G&H store about 10 years ago that there was a notice from B. Rizzini about the possibility of the forend latch coming off. I spoke to Paul Chapman and he says that we have replaced several of them. Apparently, there is a set screw that can come loose.

You are correct Bob.

Further examination did reveal the set screw.

It's a 1.5 mm hex drive.

Once I take delivery of a hex wrench in that size, I'll Locktite everything.

Ounce of prevention, etc.

holy cow what a world we live in. now we must own guns that require lock tight and super glue. 100.00 guns its expected. but high dollar guns? what do those euros think we are?
i miss old school america.

Well, you best Locktite the tang screws on a Parker too.

And the floorplate screw on a Merkel.

And the trigger group screws on an old A-5.

Don't forget the mainspring strain screw on a Smith and Wesson either. Those back out too, and at a bad time could get you seriously killed or worse.

They're just screws. Vibration attempts to destroy everything mechanical.

Be thankful your gun isn't made by Boeing. Everything would be secured with .032 stainless lock wire.

Shotgunjones,
Ah yes, good old "safety wire". I spent many hours in the Air Force spinning the tool to secure the aircraft bolts!
I can speak from experience regarding the Merkel screws.I solve that by placing a tiny amount of locktite between the taper of the screw and the taper on the hole of the action.

They weren't as careful as the Navy was about installing safety wire, if they let you use the tool in the Air force. We couldn't use it (in VA-205, working on A-4 Skyhawks). We had to twist the safety wire by hand. Our chiefs were convinced the tool would strain the wire, almost to the breaking point, without you being aware of it.

I think about it often, that and Dzus fasteners, while working on my farm equipment.

Stan,
I can't imagine doing the job by hand as you did! Even using the twist tool was a pain, especially un tight spaces. I can still see all those Dzus fasteners.
Back on track, I have two Browning BSS-SL guns that have the Anson push button. I've never considered the possibility of the buttons coming loose. I have heard of the adjustment in the rod preventing the forend from releasing off the barrels though. Either problem could be bad.
