I wonder if you had a HV barrel blank and wanted to have it turned down to a sporter tube if a barrel manfacture would do that for you? I am going to make a call to one or two of them. But just wondering if anyone had it done or if it would be a good idea to have it done.. as with some of the barrel manufactures it could take up to a year to get a new barrel made. I was just thinking of having a HV barrel turned to a sporter.
