Default Rings Around Front Of Barrel

Anybody know what causes these rings around the front portion of this IHC barrel? I've seen this on a number of Garands but never checked on it.

My guess is tooling marks from the lathe as the barrel is turned down.

Possibly to remove import markings from the barrel

Tooling marks. These are just more visible than most.

Exclamation

If the Park were fresh or in better condition it's doubtful you would have ever seen them. Tooling marks. I have seen far worse hidden under the finish and have what was a NIW barrel on my shooter 1903A3 that looks like it was machined by a dull tool and 12 year old.

When I see tooling marks like that on a garand I start to look for a stub barrel to make sure there isn't an '03 barrel attached.

Guess I should have prefaced that this is a CMP rifle & it is an LMR barrel.

Well worn Parkerized finish exposing the typical high tooling marks created when the barrel was made. Nothing unusual at all. Not that I would suggest it but, if you took a ScotchBrite pad to almost any barrel with a good finish, you'd create the same effect. A means of making it go away, visually, is cold blue or wiping the area with Caswell's blackener after a good degreasing with Acetone.

exactly, seen many that had a similar look, all worn just a bit,

run your finger over a few and you can tell,

not really, would have to remove a good bit of metal unless very very lightly stamped
