Though we might be a touch biased, there is no greater collection of firearms then what we have here at the National Firearms Museum. A recent addition is prime example why.
Around 1890, firearms empresario Horace Warner decided that carrying both a rifle and a shotgun was a waste of space and energy. So he took a 1973 Winchester 38-40 rifle and added a 12 gauge barrel to the stock. The sights were moved, fronts raised, and a mechanism for firing the shotgun was added.
It might look a little tricky, but we're told that it worked like a charm. Not that a trip down to the range wouldn't be great fun, but there's a good chance that damascus steel won't be up to the challenge.
True works of art like this and more can be found round every corner at the National Firearms Museum.
