Are there available rifling buttons for these platforms? I can’t find them anywhere. Even hammerbutton does not have them. Or is there some rifling button with specific characteristics that work, but they are not specifically labelled as AR15/M4?

Tell me you shouldn’t be making rifle barrels without telling me you shouldn’t be making rifle barrels.
Seriously, give up this project. You don’t appreciate the quality and precision that’s required, and trying to make a rifle barrel on the cheap is going to get you seriously injured or killed. Buy a barrel for $100 or make a 9mm.
