I've been looking into the Grendel cartridge and apparently it works in the AR-15 and using the AR-15 standard magazines however you can't stick as many in thereto convert it to 6.5 Grendel it will require a new barrel(either type I or type II), a type I or II bolt/BCG(depending on the barrel) and 6.5 Grendel magazines.
