  1. Awesome performance 5 Star Review

    Posted by on 22nd Mar 2018

    Bought this blank to turn on my lathe at home for a 224 Valkyrie pqroject. I chose the 1-8 twist , because I was not planning on using 75gr bullets or lighter projectiles. The blank was turned to a “Spr” contour with a rifle lenght gas system. With an .o80 gas port drilled, the barrel cycles perfectly. With Federal 75gr Tmj ammo, the barrel will shoot 1 moa, with 70% of the bullets grouping better then .5 moa . Pulling the factory bullet and replacing it with a Hornady 75 bthp ( Mexican Match) the barrel will shoot .5 moa. I used several Gm barrel blanks in the past for various gun project, and every barrel has been a great performer. These blanks are a great value.


  2. Great value 5 Star Review

    Used this blank to build a medium weight AR (.840 under the handguard) Shot a .6 moa 5 shot group while tuning gas port. keep your tools sharp when turning these blanks.


  3. Very nice performance 4 Star Review

    Posted by on 25th Nov 2014

    This 41v50 metal is HATEFUL to cut. It does turn out a nice finish if you do your part, but it is not fun to cut on the lathe at all.

    The bore is really nice and the consistency is great.

    Despite the 41v50, Green Mountain is a pleasure to work with and their products are impeccably priced.

    Thanks


  4. Great Barrels, Fair price and fast shipping. Great Customer Service. 5 Star Review

    I have used quite a few of the Green Mt. Barrels and they all have been excellent.
    Fast shipping, great customer service, and if you are rolling your own, you cannot beat the price.
