Part 3 is up.

In this one I installed a steel breech, an extended bolt and solid pivot pin.  Chrony tested each step to record any improvement.  I also replaced the transfer port with a piece of 1/4in poly tubing with id of 0.17in, to show why the transfer port needs to match the valve and barrel.
