the ar bolt carrier can be used in 6.5 Grendel and 6.8 spcii/Valkyrie as well as 5.56 and 300 blackout. the difference is there is a designated 6.5 Grendel bolt type ii that should only be
used for the 6.5 Grendel cartridge. just like your 6.8 bcg has a specific 6.8 spcii/Valkyrie bolt that can only be used in 6.8 spcii/Valkyrie ar's. Your best bet is to buy a second designated 6.5 Grendel bcg or purchase a designated 6.5 Grendel bolt type ii. however, you could get confused on what bolt your using or left in the carrier when switching rifles.
