.223 vs 5.56: A Comparison


One of the most often seen tropes in the gun community– and even by some in the firearms industry to an extent– is that the designations “223 Remington” and “5.56x45mm NATO” are used interchangeably in a sort of “six of one, half a dozen of the other” kind of indifference. 

However, there are at least a few, sometimes important, differences between the two that the savvy black rifle (or pistol) owner should keep in mind.
