Years ago I purchased a PTG Bolt and Bolt head for a rifle I was going to convert from 223 to 308. I never installed it and forgot I even had it. Anyways, Is it worth messing around with in my recently acquired 12FV or is it a solution looking for a problem. Its the standard bolt face and my 12FV is a 6.5C. I might just end up selling it unless there's a compelling reason to upgrade.
