| are all military profile barrels chambered for 556. all i have seen chambered in 223 is bull barrels. i am new to this game and looking to learn all i can. the particular barrel in question is a 16 inch barrel and has no markings on it. why do not all companies mark their barrels? also how do you identify one brand of upper reciever from the other? |
