^^^ Gentlemen:
Anyone who thinks that Colt ever made a ".223" AR-15 that was chambered
any differently than a 5.56mm AR-15 needs to find another hobby, because they are not smart enought to participate in this one.
The entire 5.56 v/s .223 "controversy" is silly on it's face for
any rifle, never mind a COLT manufactured AR-15 that uses the SAME barrels as military issue.
Now... anyone else other than me ever see a .222 chambered AR-15? That's a different cartridge...
