    10.3" .070 Barrel

    Posted by Corey on Oct 10th 2019

    I honestly don't know why anyone would buy a DD or Colt barrel when these have the same or better quality! Very accurate and a great finish on the barrel. Wish I needed another one, I wouldn't hesitate to buy this again or recommend to a friend.
