re: Anything I should check on a old Browning A5 before firing it?

I inherited a 16 gauge several years ago from my grandfather that hadn’t been fired in probably 50 years. I sent it over to my local gunsmith to give it a once over because I just didn’t want to risk anything on a really nice shotgun. The gunsmith did a good job of explaining what he was doing like I was a child. He spent a good bit on time talking about the rings, so I’m sure that’s probably near the top of the list. Cost me about $100.
