The upper (minus the barrel and minus the MB) might be ok to use, some guys do that with bca stuff.
As for barrels,
https://www.armorally.com/product-tag/ba...-5-grendel
has 2 nice 18" BA barrels, good site to deal with.
You can get a good upper assembly from using either Aero upper Rcvr or BCM's, then use a matrix HG from joebob's.
Add gas tube and GB and you're off to the races.
Aero even has some complete uppers but I build my own.
