I am going to build a 9mm upper of my own design for my M4 Carbine but I would like to retain its original look by turning a barrel blank to a similar profile. Is there anyone here with a drawing of the outside dimensions of the barrel ? Thanks !

Im interested. How accurate are those specs?
I suppose I could figure it out.
