    Guys i need to know if .223/5.56 bolt assembly can be put in 6.8mm bolt carrier. Are those 2 calibers' bolt carriers are the same physical and spec? I was thinking the difference only the bolt carrier head which it extracts out the shell casing.
    Please correct me if i'm wrong and feed me with the right answer.

    Thank you

    The carriers are the same, just change the bolt to match the case head on the cartridge.
