    The builder i will be going with to complete this kit said this particular kit is very problematic to complete. The main issue he has is that the trunion has the bullet guides already installed which makes it impossible to attach the barrel without having to cut out and then replace the inserts afterward. It takes a lot of time and costs more money for the customer for the extra work. He said he doesn’t understand why a company would include a trunion like this in a kit?

      Please reach out to us directly at [email protected] as we can exchange the Trunion out for you for one that does not already have the bullet guides installed.
      If you wish to purchase this kit without them installed, please leave a comment in the notes section or reach out to customer service before placing your order.
