Buying Mags Question - 5.56

[amtt81]

When buying mags for 5.56 - do they have to be marked as such? Most seem to always say 223 - but the rounds are the same size dimensionally right? Its just the thicker casing and higher pressures

There is no difference in the magazines. The only thing you should be concerned about with 5.66 vs. .223 is the chamber of your gun.

Buy Pmags. Then they are all marked 5.56.

but does it matter on the metal mags? Anybody?

No. .223 and 5.56 mags are all the same.

It doesn't matter on any of the mags.
