Also, I'd suggest you remove the extractor and take out the O-ring and plunger. This makes it easier for the extractor to snap over the case rim upon chambering.

Are you saying to dissassemble the bolt, and reassemble everything except the ejector and ejector springs (part 65 and 66)? Are those the "plunger"?

Are the O-rings the bolt gas rings part 61?

There is normally an o-ring under the rear end of the ejector along with the spring. Believe that's the one he's referring to.

What stock is that? Does it have a QD mount to remove it?

I am considering an A2 tube chopped with Carbon Fiber in the middle and paying the weight penalty for the folding adapter.

Smoke Composites. No qd mount for removal.

Oh yeah, learned that one lol I have 2 bolt BCA uppers (6arc and 6.5g) and neither would chamber a round without significant force, I pulled the orings and plung but left the spring, they work perfect now.

You pulled the ejector plunger? Or is there some type of extractor plunger as well? I've torn down a few ar bolts but haven't encountered a plunger for extractor.
