Build it right and it will shoot any in spec ammo.
Thats just not true though, I have seen $2k/top-tier rifles (LMT, Noveske, BCM etc) jam up on steel. You are right though, checking headspace is not a big deal, and should have been done in the first place. I just firmly believe it is most likely a tight chamber and related to the poor characteristics of steel cased ammo. I'd bet his headspacing is AOK already, but we will see in due time.
You will note that I said "in spec" ammo. Shitty ammo is by definition not included in that description. Drop a few into a case gauge and you'll see what I mean.
Well that exploded quickly....
My go/no-go gauges are due in on Thursday... I'll update the thread by Friday w/ results.
It's funny you ask about the brass. I noticed this too and went to re-check some of the brass I took from the range. The brass didn't have any signs of blotchyness on the case sides, but a few looked had some witness marks from where the ejector contacts the case. One of the pieces had a missing primer, but I have no way of telling if it's one of mine, or one of the guys that were shooting ARs around me.
Edit: it's chambered in Wylde.
Change your extractor with a new BCM one. If the current extractor is shaving brass off the lip it could be the culprit of your bolt/case jam.
No, I think I did 2 types of steel, and also brass, but not since the cleanup. I think the one in question right now is the WPA steel case, which at least doesn't have the lacquer. I just wish I could get this thing in front of about 10 of you, and have some people who know what they are doing see what's what. I still haven't ruled out magazine problems either.
I guess I'll see you tomorrow.

"Wolo" has also offered to come help out. I guess he is also heading to Bob's and lives nearby the 200.

Wanna meet at Bob's at 10:15 or so?
Good to meet you guys and shoot some today. Glad we were able to get your extractor doing its thing too. Only bad part about the whole day is that now I need to buy an ACOG.
OK, I got the stuck casing out:

I inspected the ejector and it looks like it's in pretty good shape:

While disassembling the ejector assembly I noticed some plastic snubber in the ejector spring (shown in picture with red arrow). Has anyone seen one of these? I checked my other AR, which didn't have one, and since this BCG's ejector seemed "tight" I removed the snubber. It now feels similar to my other AR's.

Thanks for soiling up my thread with gun pics!!
Any pics of this "donut o-ring"? I'm pretty sure my extractor spring has nothing of the sort.
Edit: Post 42 shows all of my extractor hardware.
yea... my BCG doesn't have any O-ring in the extractor assembly. Where's that sit, around the spring assembly?

Good info, thanks!
For those who don't want to click the link:
So, a heavier spring would also have helped instead of the "donut" o-ring? Does that spring just go weak over time or from usage?
Coyote33 there are a few fixes. That donut is quick and easy. I personally run wolfe springs in my guns, and typically don't need optional upgrades.
(aint it fun meeting Sir Gwain in person? He looks nothing like his avatar. lol.) Gwain, I'm glad you are putting them ar parts to use.
