    Freebore the muzzel would probably be best

    What is free bore? I heard the term but never understood what it ment. do they take out all rifleings or just near the crown ?

    Cut the crown back approx. 1/10" and reface it. Best to do this on a lathe but could be done with hand tools.

    I wouldn't "freebore" or "counterbore" an M1. The gas port is too close to the muzzle and opening it up will give cycling problems.

    Big question would be does your rifle need a new crown? How does it shoot? You may be able to just touch it up with a crowning tool instead of cutting back...depending upon how worn the rifling is at the muzzle.
