    If it won’t make 500 rounds of Federal and IMI 5.56, something is wrong.

    If he has to clean it and start picking through ammo to find something that runs, something is wrong.

    I wouldn’t waste another second or penny on it.

    You assume that all 500 rounds were in spec. Which, as we all should know, occasionally they aren’t.

    Used to be, around here, we would try a few minor things, get a better feel for what’s going on. Now we’re at ditch half the gun as first step.

    I miss the good old days.

Many people look at 9/11 and wonder how we can stop an enemy like that. I look at FL93 and wonder, "How can we lose?". -- FromMyColdDeadHand

    I'm tracking with your suggestions. Gonna re-spring first. Failing that, a BRT tube (suggested). Upper has a good, accurate barrel on it...is zeroed with my irons, RDS and thermal.

    Not gonna shit can it so easily.

    Those barrels are a known quantity/quality and from experience, I wouldn’t bother.

    With the cost and availability of good ammo, and the scarcity of time, a new barrel is cheap.

    Until you have to pay someone to switch it.

    And this is the first time I’ve heard that bcm 11.5s are so horribly over gassed.

    I am having trouble understanding why an overgassed rifle would fail to return to battery. Am I misunderstanding the acronym?

    It makes no sense to me either.

    One FTRB…..so scrap the upper.

    That’s hilarious.

    I don't understand how "horribly over gassed send it to the dust bin" equates to what is essentially a 2% failure rate (roughly 1 FTRB every 500 rounds?) Are all the mags you are using of the same type and manufacturer?

    Gen 3 pmags, newish NHMTGs, refurbished NHMTGs. All aluminum have either sprinco or SAW red springs w/ magpul followers.

    Upper is not getting shit canned. Green spring from sprinco is inbound and I will update the thread after next range sesh.

    That's a 0.2% failure rate. Higher than I'd feel comfortable with, given quality ammo, but not a crazy rate.
