Does anyone have knowledge of what the military considers the barrle life of an AR-15?
I'm wondering what the effect of full auto fire does to the life of 5.56 barrels. Thanks, Tom I. |

Quoted:
The change the barrels when they fail a throat erosion test. Not at a specific count. The count can vary wildly based on firing schedule and type. Could go anywhere from 6000-20,000 rounds reportedly. Full auto fire will not damage or shorten the life of the barrel unless you are running thousands of rounds in a cycle to where you could overheat the barrel. Like said before it varies. |

Under a 1,000 on full auto runing wide open. M4 535 shots M4-A1 911 shots Link been posted before many times controlled semi operation is much much longer. |

Even in the mil we NEVER just did mag dump after mag dump. I am meaning run in burst auto fire no one is accurate running mag dumps and it is not practical. That is torture testing pushing the machine to its limits to make it fail. |

I'm actively trying to shoot out a 14.5" Bushmaster Brl. At 11,211 rounds fired as of this afternoon all I have discovered is even inferior quality brls last longer than I have been lead to believe. The expectation (as in budgeting for a new barrel every ten thousand) will often times be more conservative than the individual example. |
