  1. great replacements 5 Star Review

    Posted by on 11th Nov 2016

    I have used Green Mountain barrel blanks for many projects. Good quality metal that turned easy makes a great finish wether what your desired outcome. The accuracy of these barrels are in many cases better than a factory barrel. My project list has gotten a lot smaller due to the price and quality of these barrels.

    I have used quite a few blanks from GMB and all of them have turned out to be high quality and a great value. This one I turned and replaced the 5.56 barrel on a Mossberg MVP. Turned out great

  3. dissapointed 3 Star Review

    i put this barrel on a mauser action and have had only mediocre results. it shoots two inches plus with ball ammo. and with 210smk with many different tests only able to get about 1.25" at 100yd for 5 shots. some times it will print a nice group .8 then the next will be a 1.5". i maybe expecting to much from this barrel(for the price i paid) but i was hoping for it to be consistently under 1" with match ammo.

    An excellent barrel for my wildcat project. Barrel seems to have very smooth rifling. If you have the capability to contour a barrel this is an excellent deal.

    ...on a Remington Model 7 action sold by Brownells went well. Beautiful blanks at a more-than-reasonable price!
