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

*Please note: a magnet will pick up metals used as binding agents for this projectile. THIS IS NOT STEEL and any indoor range with some degree of ammunition knowledge will recognize a frangible projectile immediately. However, there are some that will insist that anything magnetic IS steel and won't let you shoot it. Please make sure your range is on-board with frangibles before you purchase these.

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