Bore Stores sure look good to me. They approximate what I was dreaming up in my head...A product called Bore Stores
I made myself a rack very similar to what you have here. Made two of them for pistol barrels, and then I made a rack sets on the barrel supports that were in the safe to lean rifles against. I made this so that it would allow the barrel lug to go in between and a grove to let the barbel pin in the locking bolts to set down in. That safe has two sides to it so rifles set on one side and barrels both rifle and pistol. Getting crowded in there, don't know if the bookkeeper will let me get another safe.I have never been a big fan of storing any gun in plastic or a case of any kind. Mainly because any kind of moisture in there will cause rust over time. that being said I also was looking for a way to store my Contender barrels. So several years ago I decide to experiment on a rack for the gun safe. It is nothing special but it allows the barrels to stay in the open. I have never had a problem with rust on any of my barrels being stored like this.
