Some stuff works, some doesn't...even if they are supposed to be the same DPMS pattern.
I built mine on an almost completely Aero M5 setup, only the barrel (Criterion) wasn't Aero.
If you got a Palmetto lower, then I would stay with mostly their parts.
Triggers, barrels, and bolts seem to be the most cross compatible parts with the AR10, not including furniture, but those are still far from universal.
