So you don't have to guess on spec's. Google No4 7,62x39 or No 4 223 Enfield rifle owner's in Australia have been doing this already. The 7.62x39 ammo is banned there, so everyone is
converting them to 556. They found that the No4 is a better rifle to do this with than the No3.
I looked at all of this and found it interesting. The British also convert No4's to 556.
