Can I register both calibers (300 aac and .223/5.56Nato)?
Does each upper assembly have a different serial number?
In Puerto Rico I can only buy ammunition of the calibers that I have registered in my name.

Hi Jose and welcome. Yes, both will be registered on your FFL paperwork. Cheers, stay safe and enjoy!

I'm guessing that because this comes with the .300 Blackout upper, both would be Registered, so you can obtain both calibers when restocking you ammo.
