The exception to this is the Mini 14 Target model. Ruger chambered this model in .223 to improve accuracy. I don't know if they ever changed it but when the Target model first came out the manual said you could fire .223 and 5.56. I called Ruger about this and they told me the manual was incorrect. You should only fire .223 in the Target model.

Somewhat on topic, if you have a .223 marked barrel, can you have it "re-bored" to 5.56 or .223 Wylde by a gunsmith? I was hoping you could, but after seeing the chart posted by rp55 and seeing both + and - dimension differences, I'm guessing "no".Comment

So basically the 5.56 is a +P or like a .357 magnum is to a .38 Special."You can't stop insane people from doing insane things with insane laws. That's insane!" -- Penn Jillette

Yes AR mags should feed both 5.56 and .223 with no problems. The cases are the same or at least real close, the main difference is the chamber on your gun and the pressure the round produces.Comment

Yes.
5.56 guns can easily handle .223, but not the other way around.Comment
