Frank's Review of Aero Precision M5 20in .308 Winchester RM15 Complete Upper Receiver

The only issue I have with this product is I can’t find any ammo caliber information marked on this complete upper. Isn’t that a big safety concern? Every gun I have from $100 to $2000 has that info marked somewhere.
