As I debate the parts for my AR build, I figured I should really find out the difference between the .223 and 5.56… I did some research at work today (LOVE MY JOB) for an easy-to-understand article about the difference. Surprisingly, the USCCA didn’t have any articles about the difference in our blog!
But our friends at Palmetto State Armory did!
If you have an AR, what caliber is yours? And why did you choose it?
