    Thank you for including the detailed drawing. I purchased one of these barrels about a year ago, and I am in the process of designing some one off parts for my build that required me to manufacture a new barrel nut and that drawing saved me some time.

    More accurate than original barrel. Everything fit as it should. Will see if they last longer than original for our NFA customers.
