I have gone over it from top to bottom I checked the muzzle with my streamlight and I could find nothing. When I got it it was totally wrapped up in the preservative paper There are two markings on each side of the front sight protecter but they are covered in the coating from the factory. I have some import markings on my other milsurps near the muzzle but nothing on this one.
Have a nice day at the range
