It has a monolithic upper receiver-literally one piece of aluminum combining the upper and handguard into one unit, with a pinch-style quick barrel change system. There is no barrel nut.
LMT has offered other calibers, but not Grendel. I think it would have made a lot of sense for them to do a Grendel, especially since they have enhanced bolts for 7.62x39.
