I have a Model 60. Blued with the Birch stock. It was like early 90's I think. Anyway it is the 22" barrel and after they reduced the Mag down to a 14+1 to play nice with New Jerkey. A buddy lost the inner mag tube on me. Everyone is backordered and I see there are kits to make your own. I need a few pics and a few dimensions. If anyone can help...much appreciated. These guns have 3 different sized tubes from what I can find. so it has to be the same barrel length AND mad capacity.
