To be fair, it isn't clear if he used two bolts, he just said carrier, so the extractor could still be in play.

And Lube!
Good call Q I guess I skipped over the part about 2 uppers . mags could be the problem but that shouldnt cause the first round to not eject , but hey I have seen some pretty strange sh!t on these in the last 12 months of owning ARs . I still suspect the extractor spring may be weak , chipped extractor or maybe just needs the rubber insert if it doesnt already have one

Lemme guess, Bushmaster? They do not stake the gas key screws and this happens all the time.
NO, NEVER! shims, are in no way a fix to what the problem is. just dont do it!

you've tried 2 uppers, so its not the gas port.
you tried to BC's so its not that.
you didnt say if you tried 2 different bolts.
and you didnt say if you tried different ammo, or mags.

also could be the extractor,
or the buffer spring.

you can swap the bolt itself first.
if theres still a problem buy a new wolf buffer spring.

perhaps, you could post pics of the rifle. maybe any jam that happens. also pics of the buffer, n spring.

Why is it I just feel like this one has a rifle length spring in a carbine tube? Didnt I say that in a above post ?

Very possible since this sounds like something wrong in the lower. But we just don't have enough info from the OP. Don't know much about this rifle so far.

I have tried swapping bolts and I'm using federal 5.56 x 45 not reloads, no wolf ammo, I've tried two different 30rd pmags. I have no idea how to tell if the spring is a carbine length or rifle length spring.

Take some pics of the rifle and post them here...that will help identify the type of stock and buffer tube you have...then measure the buffer spring. A carbine spring will be shorter that a rifle length spring. (see below). Putting the wrong spring and buffer in the tube will lead to cycling issues. You can use either buffer system as long as all the parts are of the same type system, i.e. a rifle length (A2 style) extension type will require a rifle length spring and a rifle system buffer...same goes for carbine setups.

gotta love the internet....

Today I went to the range to try the shim idea for the first time, and it worked! I blew off 400rds with not a single jam, but I will still check the buffer and spring to make sure I don't have the wrong one. Thanks!

You're fixing the symptoms, NOT the problem.

I don't even like to shim starters. They don't come from the factory shimmed. Shimming something that goes boom deliberately is a bad idea.
