I watched the Geissele shot show 2018 live video thats like 110min long and he mentioned working on a extractor made from 13-8 SS somebody's working on something... And good things WILL follow. The only question is when..? Sounds like the Geissele clan are really stepping up their game though. Lots of new goodies. As usuall great info from the "BILL's" (Bill A. and Bill G.) Love watching thier videos.
Now if only we can convince him enough to make a grendel spec extractor. Release the hounds!

No one ever got a group buy going on extractors. I'm not aware of any material difference from the Millennium Precision Manufacturing ( Monster Group Buy bolt) extractor than what Alexander Arms extractor uses in their bolts. The 6.5 Grendel extractor is different than a 5.56/223 extractor to accomodate the different diameter case head and rim thickness.
I have a spare 6.5 Grendel extractor I bought from AA plus a spare Group Buy bolt. To my knowledge Maxim uses the same material for 6.5 Grendel bolts and has produced bolts for different barrel manufactures. Many companies require nondisclosure agreements and are reluctant to give out specific details to their manufacturing process in regards to bolts/extractors.
If I were needing another 6.5 Grendel extractor I would check AA first. When I bought spare extractors a couple years ago AA had the best price but I called to request an option for cheaper shipping. If I were going to order online from AA I would purchase extra magazines or other products to offset the cost of shipping.

I wish i could remember who had it. But i swear someone had s7 extractors and i want to say they also sold type II grendel bolts. So its not a stretch to think they might sell them. It wasnt a new co. They had good rep. Well recognized brand. (Re-reading this cracks me up looking back)
Maybe it will come to me..?
Mind over bad memory... A quick google search results:
We just can't help not accepting the status quo. Bolt carrier groups are available aplenty, but few could meet our exacting standards for performance and value. Seeing "MIL-SPEC" as just the starting point, we set out to ensure the best options are available for our demanding customers. Improvements include using 9310 tool steel for the bolt, which is stronger and nitriding the assembly to increase surface hardness, decrease resistance, and have superior corrosion resistance compared to typical chrome and phosphated bolt carrier groups. All bolts are fully MPI tested to ensure the material is sound and without defects. Bolt lugs are chamfered 45 degrees to ensure reliable action for even the highest pressure hand loads and fast lightweight actions. Extractors are S7 Tool Steel. From there, the extractor is sprung using the spring, o-ring, and silicone insert. *When ordered with a barrel, Faxon personally checks and guarantees safe headspacing. If ordered through the barrel webpage itself, Faxon offers a full matching service with unique laser engraving on both barrel and bolt.

Details at the bottom say s7. Is this typical? Idk. If its news to anyone maybe they can get the ball rolling (again)
