Are all Grendel extractors interchangeable?

[VASCAR2]

With Pacific tool (PTG) doing a lot of the chamber reamers you can bet that Columbia River Arms (BHW) will have one of the first 6 MM ARC on the market. Hard to say if market will push the .125 bolt face depth or .136. I’m invested in .136 bolt and would only buy a 6 MM ARC barrel if it used a .136 bolt. My bet is Columbia River Arms (BHW) will use .125 bolt face. There is still a market for a quality bolt with a .125 bolt face but having both bolt face depths creates more confusion and restricts production capacity.
