    And this is another one of the many reasons why Genuine COLT Parts are better than the "other guys".
    You have any more reputable source, perhaps something released by Colt themselves? A few minutes of searching on my part has turned up no such thing as a "hammer forged" RE, but I could be wrong.

    Personally I only use REs from BCM, Colt, LMT, KAC, DD and VLTOR. Everything else is suspect.

    This from personal experience.
    Also I believe that since a fighting gun's stock might have to be used as weapon, (or other severe service) the receiver extension must meet the higher standard.

    Search "Buffer Tube Basics" as a thread title.

    There's absolutely NO REASON to run a Commercial piece of shit. A decent part is only usually $20 more.

    Even amongst the "mil spec" REs there's a pecking order. I have some rough ones. REAL Colt REs will have a mirror smooth finish inside that you can actually hear and feel when cycling the charging handle.

    Reading the stickied threads at the top of this subforum would have netted this: https://www.m4carbine.net/showthread.php?t=7009

    ...which contains the thread markm specified, among others that contain answeres to many, many general technical questions.

    Between that and Clint's post, this one's pretty well answered. Again.
