I bought a gun in state, in MA. Do I still need to register it?

So I bought a rifle at a gun show last week in MA. Do I still need to register it, or was that done automatically because it was bought in state?

This is the website to register firearms, but I can only find things for if I bought it out of state, or sold one.

Thanks for any help!

edit: I do have my FID and I bought it from a licensed dealer. I was just asking if there is anything else I need to do on my end.
