You are lucky anything is left. I was up hunting at inlaws several years ago and the people's house next door burn't down. We were over the next day checking it out and could see what was left of the gun cabinet and the guns that were inside it, or what was left of them for that matter. Funny got an education of how well guns are made. The guns like the mossberg shotguns, the metal was all melted.
But the remington gunsthe stocks were burnt off but the barrels and recievers were still solid.
I'd be willing to bet that the temper in the steel of any of those guns was destroyed by the heat treatment they got in the fire. It only takes 400-600 degrees F to do this.
I would NOT ATTEMPT to fire any gun that went through a fire, unless it was protected in a heat-reistant safe that was rated to temps higher than the fire produced, and that came out of the safe with NO VISIBLE DAMAGE to the wood or plastic components!!
