  1. Impeccable craftsmanship! 5 Star Review

    Posted by on 12th Nov 2018

    What a beautiful barrel! I purchased the .223 Wylde 16” barrel for my build, and it’s amazing. It has not been fired as of this posting. But, I have no doubt it will live up to what I’ve seen and heard so far. If I ever build another rifle, you can bet I’ll be back for another barrel from Green Mountain!

  2. GM-M57 barrel 5 Star Review

    Nice finish; fit properly, easy install with proper headspace; I have not yet fired for break-in or accuracy.
