I am interested in reducing the weight of my 416 upper. I contacted Jayson at IGF and he said that he could take care of me. He recommended turning down the barrel under the hand guards to the Noveske Profile which is about .710. My question is, what is the original measurement of the barrel as it is now? I do not own a pair of calipers, so it is not something that I can measure on my own.
Anyone have this process done? I know/understand that Jayson knows his stuff and knows what he is talking about, but does anyone have any pics/experience with doing this?
