Measure the length of the bolt, and the length of the firing pin, with a caliper. Lengths here should not be a problem but just to eliminate them from a cause...
How many rounds downrange (looking for the amount of breakin)?
What bolt/bcg do you currently have, is the bc phosphated or what.
yes, maybe the trigger group/hammer spring.
maybe smoothness/cleanliness of the bolt, inside and out. Do you remove the extractor when cleaning to get at the insides of the bolt...
Do you have another bcg to try, I'm guessing by your comments - not. Having a few key spare parts is a really good idea btw... 1 is none, 2 is one.
These are some ideas that occur to me.
