  1. Another Century Tantal Rescued 5 Star Review

    Posted by on 22nd Aug 2017

    Excellent chrome lined quality and accuracy out of a formerly keyholing Tantal!

    There's a reason Green Mountain are well known for their barrels.

    Buy with confidence.

  3. Saved my Tantal's Life! 5 Star Review

    Posted by on 3rd Jan 2017

    I just about gave up on my CAI Tantal. It keyholed right from the start. I waited several years for GM to produce its replacement barrel and it was worth the wait. With my new GM barrel, my Tantal is a joy to shoot. It easily shoots 3-3.5 inch groups at 100 yards with iron sights and the lousy wire stock that provides no cheek weld. In fact, my GM barreled Tantal is more accurate than my Arsenal SGL31. Thank you Green Mountain!

  5. Amazing barrel 5 Star Review

    Posted by on 11th Oct 2016

    My friend and I built our Tantal kit about a year or so ago and I can now say that these barrels are the best out there. It installed easy on our kits, I got it out to the range, and it is extremely accurate. I love these barrels. I highly recommend. Truly brings these kits back to their former glory.

    Long live freedom.
