AR-10T upper on a SR-25 lower?

Hi,
Question: Does anyone know if my Knight's SR-25/.308, lower receiver can be used with the new AR-10T/.300 SAUM upper barrel assembly.
If they are compatable I won't have to purchase the AR-10T lower which is illegal here in the PRK (Peoples Republic of Kaleefornia).
I already have the SR-25 legally registered with the State Commisar of Justice.
