Import stamp is required for import of military firearms into the USA, and include an abbreviated co. name, location, and caliber of the weapon.
If numbers are really ground away I'm GUESSING someone's hack job, as the Ruskies at least stamped X's thru offending numbers.
But good close up photos are a must.
