I did.
In theory.... mostly yes. Sort of. Others will be able to say better than me, but for a time there were two standards for Grendel bolt and chamber related stuff; though it seemed to have settled on just one standard a long time ago, so unless you're getting used or really-old-stock, then yea, it probably will work.
For me, I had a PSA one snap. It was interesting to see just how paper-thin the metal is under the groove, the only thing really holding the extractor together at Grendel dimensions, is the tab thing where a bolt-lug would otherwise be. PSA ultimately warrentteed me an entire replacement BCG, but in the meantime, I replaced the extractor with a Black Rifle Arms one, that seemed cost effective. Been running that one ever since, seems to be working fine.
I did pick up a few Red X arms ones as emergency ones that I tape inside my pistol grip; But I can't say I recommend them. Some of the more experienced guys here who know a lot more than me, very actively DON"T recommend them.
I do note the RedX ones don't have the inside corners relieved, which apparently causes problems, so I touched those points up with a precision file. No idea if they actually work; I just picked them up as very low-cost emergency field repair units.
