      Good Barrel

      Posted by Peter on 4th Jul 2018

      Inspecting this barrel, I found I love it. Correct (non f-marked) FSB, no m4 feedramps, 0.625 under FSB, the finish is dark grey and very even, and the bore looks like a mirror with the chrome lining. I am very happy with this barrel and would buy again from TNTE.
