Forgive me if this is listed anywhere.... my limited free searches came up empty. h.gif Anyways. I have a XM16E1 Colt upper and what appears to be the original 1/12 MP barrel. So the big question is.... 5.56 or .223? Were all the military parts 5.56mm? Or was the early stuff .223? I know the earlier magazines are marked .223 until around '69. Thanks, Brachus |
