Chrome-lining will extend the life of your barrel and make it easier to clean. It is commonly thought that chrome-lining degrades the accuracy of the barrel. This is because during the chrome-lining process, material is chemically removed from the bore and then built back up with chrome, destroying the bore uniformity.
Our unique chrome-lining process maintains bore uniformity, providing you with the advantages of a chrome-lined barrel without sacrificing accuracy.
