I saw 1 that a guy was making that had a lazy susan kind of set up in it. It held, I think a dozen guns. You rotated the "lazy susan" thing in the center from the outside so that you could see all of the guns without opening the cabinet. It was really cool, I have been thinking about building one myself if the wife would only let me have another cabinet in the house.
This kind can be made with a triangular footp[rint that occupies a small corner space in your room, takes up little space for the number of guns it will store, and gives you instant access to any gun in it, without impingining on the space of any of the others!!
