As Carteach learns the way of the AR, details begin to emerge. See, all the AR platforms in my past have been new up to this point. 'Fixing' them has not been an issue.
This newest stallion in the stable is anything but new. When I first took it into my grubby little hands, I had serious concerns regarding the bore. It appeared shot out. What it was... in fact... was so heavily copper fouled the rifling looked weak. An hour or two with Hoppes copper fouling cleaner and a few good bore brushes later... and the rifling looked darned good.
Function checking did eventually reveal an issue. Sometimes, rarely, but sometimes.... if the charging handle was eased forward the bolt carrier stopped half way through the receiver, as shown here:

Now, if one releases the handle, all is well. When shooting, no issues surface. It's only when the bolt is allowed to slowly go forward that any problem shows, and even then it's one in a dozen times. That said..... a problem is a problem and indicates something not up to spec. Thus, the rifle was field stripped and carefully examined (With help from the AR gurus at the rifle match). No problems at all were found, except this wear on the bolt carrier:
and of course that explains the issue perfectly (I TOLD you it was a well used unit).So the Fat Man needs an AR bolt carrier. Preferably, an M-16 carrier as it weighs in an ounce or so heavier than the AR-15 version. I'd like to slow the action speed just a smidge, and a little extra weight there would just suit the purpose.
So... the question: Does anyone know a good seller who has an M-16 bolt carrier in stock?

Bravo Company has a pretty good rep on the forums.
Spike's is top-notch.
And finally, LMT is absolutely top of the line.
FWIW: I have no direct experience with any of these companies, but would feel comfortable buying anything from them. They have long-standing good reputations on AR15.com, which has a habit of crushing dealers that don't meet their sometimes-insane standards.
Thank you Zer... exactly the advice I am looking for. I was looking at a Spikes bolt unit, but don't know anything about the company.
I am in the middle of my AR15 build, but I haven't gotten to selecting the bolt carrier yet. My lower is a Spike's tactical with an RRA LPK. The Spike's receiver is very well made. The RRA kit fit perfect with no issues at all. So, FWIW, I recommend those manufacturers. I've heard that Wilson Combat makes an excellent bolt carrier; but, then again, they better make a good one for the amount of money they charge.
Here is the one I bought from bravo company http://www.bravocompanyusa.com/BCM-Bolt-Carrier-Group-MPI-Auto-M16-p/bcm%20bolt%20carrier%20group%20auto%20mp.htm
Buy an LMT from DSG, that is what I tend to do.
palmetto state has a good deal on one.
All good references for where to buy AR parts.
It seems obvious from the position of the BCG when it hangs up and the nature of the wear that the carrier is hanging up on the hammer - probably where the cuts are at the sides. Since the slope of that surface is not particularly critical, I would think you could smooth out those ridges and restore that carrier to full functionality for use as a spare.
Having a complete spare BCG is a good thing with ARs - it serves as a quick troubleshooting tool - if swapping out the BCG fixes the problem - Bingo!, you know where the issue is.
One note - with a high-mileage barrel, I'd keep the bolt and barrel together if you can.
I've ordered a bolt carrier from Bravo Company... mainly because they were the ONLY company I could find that listed them in stock.
While I was at it... Magpul hand guards and a couple magazines as well.
We shall see how this goes...
