From my own testing with some AA barrels.
Tune the gas system and lapp the reciver face and the bolt should last longer then the barrel does.
Changing an extractor is simple, press down on it where the pin goes through it and with your other hand use something to push the pin out and then install the new one.
I have a bolt in my 12 inch grendel that went through 4 16 inch fluted AA barrels and it and it's extractor is still going strong. All 4 of those barrels were run with wolf fmj and my 120 gold dot handloads till they died.
The round count is so high I still can't believe how how it is and the bolt is still going.
