Pressing the AR-180B bolt hold open

Previously I showed a few pictures of the process in pressing the AR-180B bolt hold open device.

We started with a laser cut then machined blank.

This is the video showing the steps.

And after the pressing operation we have a completed part ready for heat treat.
