Same thing. Get 223 dies. Loading for a AR you will want to full length resize, you will need to lube the cases. I have never found the need for a small base die, I just use a regular FL sizing die. Get a good reloading manual and read it. There is some case prep you will need to do for loading rifle and the manual will explain all of that. Also if it's military ammo you will need to swage the primer pocket to get rid of the crimp.
