    Default 9mm AR stove piping

    Can't figure this out at the moment. I've had it happen before with a 3.0oz buffer but with one has the 5.4oz buffer.

    With different types of ammo too.

    It's the classic stovepipe with the casing caught halfway out by the bolt and it's 90 degrees to the bore.

    I don't have a heavier buffer laying around right now to try

    New gun, or one that has successfully ran in the past?

    Disinfect it and try again.

    Have you by chance scrubbed the chamber to ensure the case isn't sticking, and/or changed the extractor and extractor spring?

    I'm curious, brass or metal shell casing?
    Listen to your elders. Not because they are always right but because they have more experiences of being wrong.
