M4s start breaking bolts around 5-6K if I recall correctly.
Start reading around page 43. Bolts are wear items. And of course easy run civilian guns are a little different story.No not really.

LOL.FYI: We aren't talking about machine guns subjected to harsh firing schedules for the purposes of this thread.
But, to somewhat keep this on topic...what does the report say using a mid length gas system does to those numbers vs a carbine length gas system?

offense, but how many rifles have you built?
Colt has built hundreds of thousands of them, many of which went the military and were trustworthy to be used by troops in combat.
For the $147 or so difference between your build and the stock Colt 6920's I see at Walmart, I'd buy the Colt.
Again, I don't mean any offense to you. You may very well be a skilled gunsmith who could open his or her own business and successfully build AR based rifles. But it would take some time and a lot of very good rifles before you could build up the kind of reputation that Colt or BCM has.

I don't mean any offense to anybody, but I've always assumed that I could build a better AR than some assembly-line union goon @ Colt. This ain't rocket science.
