    Rare Failure Or Not?, it stopped the gun from running

    Shooting yesterday, and had a few primers (un Crimped) come out and float around in lower. Cleaned one primer from under trigger group. Took rifle to school today and bang. Single shot only....

    Found primer material clogged inside gas key. About .6" inside. Can get it out. Is this a known matter or is this a freak deal. Seems like the stars had to align just right to get that aligned and timed perfect.

    Thanks

    It happened in Iraq several times with our BMs and 5.56 ammo. I have heard of about this happening about a dozen times since. When it happens its either crappy ammo or tight chamber.

    We had this type of crap happening on one of Pappabear's LMTs a year to two back. XM193... I think Iraqgunz gauged the weapon and cleared it of being the source of the popped primers.

    I had the same thing happen at a Triton Concepts class with the same ammo 2 years ago. In this case a spare upper saved the day. FWIW the upper was a BCM 14.5 LW middie. I've had primers popped before but that was the only time it locked it up.

    my enemies and overtaken them. Neither did I turn back again till they were
    destroyed.

    The last and only time I have had to deal with blown primers was several years ago with some PRVI PARTISAN 5.56 55gr. ammo. I stopped shooting it and have not had a problem since.

    Just remember to break the entire gun down. When this had happened to me, every time I thought I had found all the offending material, I found a little bit more. Finally took it down all the way (including receiver extension and buffer), and blew it out with compressed air. it was a good chance to clean it up anyway

    I was getting regular popped primers with independence 55gr. Stopped using that and haven't had a problem since.

    I've only had it happen to me once personally, and that was shooting MK 262 out of my M4, this was after shooting 30 or so magazines of M855 and M855A1 without cleaning or adding any additional lube after the initial application of slip 2000. I once had a primer almost get blown out of the case, Camp Robinson, AR, early morning in Feb at SDM school, ammo was M855, rifle, M16-A4, was clean ish.
