5.56 (Hunting/Defensive/Competition)

Brass: Offered in new brass only.

*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

Did you know that you can shoot .223 out of any rifle chambered for 5.56? See our .223 selection here.
