The forend iron just snaps off from the gun. It is held snugly by a J shaped spring which goes over center. It will be much more difficult to snap off without the wood for grip. You may have to use some leverage under the tip of the iron to pry it up till it pops over center in that direction. Just be sure to use something non-marring as you don't want to be scarring up the bottoms of the bbls. Once the iron is off the bbls should then just unhook from the hinge & can be lifted out & of course the wood can be remounted.
