I recently purchased a complete anderson ar in 5.56. I want to change over to 300 Blackout. Can I use the same upper with just a barrel swap? I even read the 5.56/.223 BCG is the same as well. Is this true and wouldn't the head space change?

You're good to go just swap your Barrel

Your bolt should be good to go. Will require a barrel swap. Check your headspace. If all thats gravy, you are good to go. You can even use the same magazines.
