    I always wondered what would happen to a F/A w/a squib. I never suffered one w/my MAC 11/9 or HK MP5, but I would have thought the damage would have been greater. I only had the factory short barrel on my MAC, but at 1200rpm, or 1800rpm w/the mac-jack, it prob takes someone a 1/2 sec or 2 to recognize something out of the ordinary and come off the trigger....

    Came across these pics. The firearm was reported to be a F/A MAC w/a 16" barrel, that suffered a squib and then multiple followup rounds. I can count at least 8 or 9 rounds, but the total count was supposed to be 10rds?? Looks like the barrel did an outstanding job of containing the rounds.

    Can anyone comnfirm that this looks like a 16" MAC barrel? It looks a little thick to me and do the threads look right??

    In regards to the pics... I had that barrel in my grubby hands when it was at that machine shop..

    The barrel is indeed made from a blank to fit a M10 upper, barrel chambered in 9x19. The original was made by John at West-Georgia Armory, as the owner wanted to do 1 of them "mini-1919" kind of things.

    Owner (Eddie -- not seen in any pics) went out 1 day, and had a pile of assorted handloads from friends to use up, take it from there.

    The fella seen in the pic (Paul) is who made the mount, he works for GE Aircraft Engines in Cincy.

    The owner bought a new blank, had our local "ARFCOM" tool & die person (Brian) cut a new barrel, same fella that does my cutting (made my stainless M11/9 barrel from my former stainless AR barrel). Brian had their "wire room" guy cut the barrel to expose the bullet stack.

    I see the myth of the "exploding barrel" with squibs is put to rest.

    :cool:

    That is a very thick MAC barrel. I don't think a regular barrel would be as good.

    Barrels explode.

    And you can search for more. It is not a myth if it happens. Low pressure stuff like 9mm and a thick barrel make it mighty hard for a barrel to split/explode. Higher pressure stuff in hunting profile barrels are not so hard to split.

    The real lesson to be learned is to not shoot reloads in a full auto.

    This doesn't surprise me. John cut the threads on my m11/9 barrel and blew up my suppressor on the first mag. He never returned my calls or emails.

    Hardly. I saw an UZI barrel with 15+ rounds jammed in it. It did not burst because like the MAC it fires from an open, non locking bolt. Any excess pressure exits the breach with the casing. A squib will burst a barrel easily if it has a locking breach or high enough pressure.
