    Check what is stamped on the barrel - not the lower. I'd bet that it is still 5.56mm. I know some Colts have had lowers stamped with .223, but the barrels were 5.56mm

    yup all colt barrels are chambered for 556 (except for the one with 24'' SS barrel if I'm not mistaken)

    I know that some MT have the barrel stamped "5,56" and the lower roll marked "5,56". The barrel of my new M4 is stamped "C /MP 1/7", not "5,56". Otherwise if you take a look on the Colt catologue You can see that all the MT are "223 caliber", and "they can shoot 5,56". Consequently my M4 should be 223.
    But the question remains the same: 223 and 5,56 chambers are really different? Furthermore, If 223 and 5,56 are different, why some Colt carbines have different calibers stamped on diffent parts of the gun?

    No, the question doesn't remain. Only your refusal to look at the answer.

    Yes, there is a difference between the two chambers. A 5.56 chamber is very slightly larger than the .223.

    Also, Colt 6400 chambers are 5.56, regardless of what you see on the lower.

    Did someone just necro-post in a thread that is over 2 years old?

    Thank You. I really don't understand this strange Colt policy. A rifle stamped with a wrong caliber!!!! Impossible to know why, I suppose
