    I see numerous interesting markings and variation in many barrels and bolts. It is very interesting and I want to know more.

    Markings found on various G3 parts ©mg-42.net 2002-2003

    Try here. Not the end all be all but it will help with many. He no longer maintains it and could not help with some marking on my G3 trigger packs but I am grateful to the effort he put into putting it together.

    Pg. 285 in the book Full Circle gives a generalization of some of the *stampings and what they are. I've searched about the markings on the back of the bolt carrier a few years ago but never came up with anything. I would have to assume they are acceptance stamps stating that it met standards. Whether each person, dept. or location had their own stamp...I don't know; would be interesting if this info existed.
