They have little single finger latex gloves at the drs. They look like mini condoms. Work awesome over end of barrel when raining.
Since I'm a real saddle hunter, I like to find multiple uses for all of my gear whenever possible. Therefore, I just use my regular condoms on the barrel of my muzzleloader. They are a little snug on the barrel but work awesome because I can roll them all the way down and they don't cover up my front sight. Before you ask, it IS a .50 cal, I'm a real man......
