Product Details

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.

5.56 77gr

Recently used the 77gr in a scoped rifle class using a 1-6x scope in a 14.5" AR. Was able to hit out it 600yd on 12x24" steel pretty regularly and was one of 5/12 students to make a clean run from 100,200,300 & 400 yd in under 20 sec. Couldn't be more happy with performance like this.
