| If I replace a bolt carrier do I need to check the head space? I just got a new bolt carrier for a used upper with its orig bolt, and it is pretty tight in there. Haven't got my lower in (should be in tomorrow), so I haven't fired it yet. Any advice would be great! |

Bolt carrier? No sweat. The carrier itself has zero impact on headspace.
Now if you replaced the bolt itself, that's possibly different. In general a new bolt will be just fine with an old barrel and vice versa. But if you're concerned, there's no harm in using a headspace gauge to verify that your old barrel isn't beyond safe use. |

Quoted:
I'm pretty sure that even army rifle that shoot hundreds of thoundsands of rounds rarely have to throw out barrels because of headspace. Set it and forget....headspace is 99% a non-issue [if it blows up...not my fault] :) Not sure I would go as far as hundreds of thousands of rounds ? I would guess the climate ( sand , muddy , etc. ) would have some bearing on how fast the bolt / barrel interface wears , as well as chamber / throat wear ? And how well it was kept clean ? Let's be safe out there . God bless Wyr |

We throw the equipment away or destroy it when we leave a war zone anyway. They say it's cheaper that way.
My first issue M16 was a POS, worn out leftover but we were still there. I was told a Second Lt had it before me. What'd we used to say about the life expectancy of a 2nd Lt. in combat? How many seconds? I never figured out how he wore it out so fast.
