16 gauge Fox rotating bolt will not be easy to find---although the 12 and 16 locking bolts may be the same outside diameter, I doubt it. A Fox 12 gauge rotating locking bolt is approximately .685" in outside diameter. I have had to make a Fox rotating cocking slide in the past and it is difficult to machine the rear pivot inside the rotating locking bolt correctly to make the gun easy to open. Some times the top lever shaft will break and cause what you are seeing with your gun. I know that I have a 12 gauge Fox top lever in my Fox parts. I think I have some 12 Fox locking bolts in my old Fox "stuff" and I can send you one to try to make work if that is what you find is wrong--take the butt stock off and look at the top lever, the top lever extension and its spring/plunger to see what is wrong. Do you have a metal lathe?

Is your Fox an ejector gun?
