5.56 is just an abrevation for 5.56x45
5.55mm= bullet diameter 45mm= case length You are good to go |

Everyone has to start somewhere my dude. No dumb questions when a mistake could cause significant harm or worse.
If the rifle is chambered for 556 (look for markings on the barrel, they’re what determine the caliber), then you’re safe shooting 223 Remington as well. The reverse is not true. |

Quoted: I’ve noticed that some boxes of ammo say 5.56 x 45mm and some just say 5.56MM. What is the difference? Same, as stated. Quoted: 5.56 is just an abrevation for 5.56x45 5.5 45mm= case length You are good to go Eta: Fixed the typo in quoted text. |

You can also shoot .223 Remington ammunition through your 5.56 rifle.

Varies by maker. |

Quote History5.56 mm is not the bullet diameter. That would be .224 inches. |

Quote HistoryQuoted: 5.56 mm = .2188 inches Quote HistoryQuoted: 5.56 mm is not the bullet diameter. That would be .224 inches. A 0.224 inch diameter bullet is used in .223 Rem and 5.56X45 ammunition. The nominal bore diameter of barrels for these cartridges is 0.219 inches. The nominal groove diameter is 0.224 inches. Both dimensions will be held to a 4 place dimension by any reputable barrel maker. This lack of naming convention is well illustrated by these two cartridges. Unfortunately, many cartridges have names that can't be traced to barrel dimensions. |

Just be sure what your barrel twist rate is. I have one AR with a 1/9" twist so it may not be able to stabilize 68gr-77gr rounds. It does shoot 55gr, 62gr, and 64gr of 5.56 rounds just fine. My other AR is 1/7" twist so it can stabilize heavier grain rounds. I know some barrels are 1/8 twist which should stabilize heavier rounds as well but I don't own any ARs with a 1/8" barrels.
