I ordered a sporter barrel in chromoly and after waiting nearly 4 months, it arrived... In stainless. This is going on a hunting rifle and I need it to have a black coating of some sort to stay with the traditional blued look. The action is a blued, chromoly Remington and the barrel is now stainless. I need a recommendation for a coating that can be applied to both barrel and action so that they match. I want something that looks good and that will be scratch resistant. I'd like to avoid using a cheap spray on product. I want this gun to last a lifetime. Any recommendations welcomed. Project is stalled until I find a solution. Thanks.
