  2. Consistent and Accurate 5 Star Review

    Posted by on 11th Apr 2021

    Have used a few of these. Made several great blackouts. Most recently turned one for a Galil in 300bo. Getting 1.5" groups at 100 which is awesome for an AK. The ARs usually shoot .75" at 100. If you do your part these barrels shoot all day.


  3. As good as anything out there 5 Star Review

    I have personally purchased several of these blanks for 300 blackout barrels and the accuracy is fantastic.


  4. 308 gunsmith barrel blank 5 Star Review

    Posted by on 5th Mar 2014

    I have been using Green Mtn. blanks for number of projects. I slug the bore when I get them and they are always exactly what they say they are, bores are smooth and uniform. All rifles I have built using these are very accurate. these blanks are turned prior to button rifling which keeps them more uniform than if they were rifled after contouring or just rifled when rough. these are low in cost but the quality is worth much more. You can turn them to whatever taper you want.
