  2. Tack driver 5 Star Review

    Posted by on 20th Jul 2016

    This was the first GM barrel that I have used in a rifle build, it won't be the last. I plan to use a GM barrel for a scratch built 1885 Winchester project that I'm in the process of milling now. Accuracy is impressive, to say the least.

  4. High Quality 5 Star Review

    Posted by on 29th Mar 2016

    Bought it to build a light weight AR. Metal is very hard, had to take small cuts on the slowest speed & finest feed. Turned out perfect. Sand blasted it when it was all done & cold blued it. Very happy with finish.
