5.56 x 45 (5.56 NATO)
This popular NATO round is offered in both a 55g Full Metal Jacket or a 77g Sierra Match King for long-range accuracy.
Brass: New or Reman (choose below)
*IMPORTANT: Though both cartridges look identical, 5.56 is loaded to a higher pressure than .223, which is why rifles chambered for a 5.56 cartridge can fire .223, but it is not recommended that 5.56 cartridges are fired out of a rifle chambered for .223
