I am looking for any information you can tell me on the meaning of these symbols on my LMR barrel. The barrel has a "P" proof mark before the LMR and after I can make out a "P" and "M" lighter etching. Just past these letters (near transition point of the barrel) I can see what looks like a rough eagle or star etched in the barrel. Is this a DOD marking, similar to a cartouche on a stock? I have not seen this symbol yet, on the LMR barrels I have looked at in the threads. Thanks for any info.
