Shooting a 223 in a match has its own set of challenges – your mag doesn’t need to be one of them. Carry 12 rounds in the ultra-reliable Accurate mags, with an OAL of up to 2.500″ (it’s actually a little more, but you’ll figure that out) and stop worrying about those stages with a couple more engagements.   Black Mags, Black Extensions, no tricks.
