If you find a print, it would be most helpful. Trying to determine the od of the rear portion of the extension, the dia of the ring, the distance from the ring face to the breech face. Need this info for a 9mm barrel that is turned from a solid piece of barrel, no barrel extension. TIAThe barrel extension is 0.9980/0.9995 I think, not near a print right now. The upper receiver bore is 0.999/1.000 for the first inch I think.
Just wanted to revive this thread as I am looking for the same information. I would like to get some barrel extensions manufactured as they are not easy to get here in Canada. Also looking for good, preferably factory, blueprints for the upper receiver.
Did you try Brownells?
