    Needing to know if I have GI parts, Commercial, or junk that needs to be replaced. Or any other pertinent info.

    Got a M1A scout/squad markings as follows:

    Receiver: U.S. RIFLE M1A
    SPRINGFIELD
    ARMORY (circle "t")
    076XXX



    Bolt: Dimple
    7790185 HRT
    AO3


    OP Rod: 7267064
    66118

    Barrel: GENESEO. IL. under the charging handle. (might be something else under the upper hand guard)

    Thanks

    Well, the receiver is commercial, and the barrel is commercial.

    Don't know about the other stuff.

    Springfield Armory, Inc never made any GI guns or parts though.

    The government Springfield Arsenal, which built GI guns, was located in Springfield, MA.
    It closed in 1968.

    Springfield Armory, Inc. opened it's doors in 1974.
    GENESEO. IL. is part of their address.

    I can tell you that your bolt was made by Harrington & Richardson(the 22 pistol people) and is a GI part. Sorry, but I can't help you with the rest. :)

    I wouldn't replace anything unless you see signs of failure.

    The receiver and barrel are commercial. The bolt is USGI. Don't know about the Op Rod. There is little and rare problem with these.

    I would keep an extractor, ejector, associated springs and firing pin as spares. If the extractor flips off to never never land you won't be down.
    Some commercial Springfield extractors did not have a deep enough indentation to hold the spring. Keep USGI spares, just in case.

    There are a few legally transferrable M14's on the NFA registry.
