  1. We'll know tomorrow 5 Star Review

    Posted by on 20th May 2020

    To whom it may concern,

    I have yet to try the barrel. Just had it installed a week ago since I am not tooled up to perform. Khyber Pass Tactical installed. They have a great reputation. I've been extremely busy at work and have not had a chance to get to the range. I am taking a few days off and plan on hitting the range tomorrow. I will let you all know how it goes.
    thanks for the follow up

  2. ak74 tantal 4 Star Review

    Posted by on 23rd Apr 2020

    Great product for sure made the rifle shoot straight again, and not keyhole like it was doing. Excellent chrome lined barrel. The gas port was already drilled, so no need to buy another bit, all of the pin holes were drilled except the barrel pin over all very happy with it

  3. 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.

    Great barrel. Machined wooden Jig to tack weld receiver. Tig weld complete. Now barrel hardware ready to pin. Looking forward to sighting my Tantal in. Thanks' G M.

  5. 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!
