Just got my barrel and it looks perfect. Machining great, bore mirror chrome, gas regulator, sights, threaded end. Have to check fit for my Hitachi and get time to take it out. Don cautions to stake the sight after drifting it to zero. Going to get my gunsmith to repro a carry handle based on my other barrel. Where are you going to find one? Get it. Thanks Don for taking the time to craft these.
