Gauging – Viking Armory

After I made the plugs for the iGauge to check firing pin protrusion I realized 2 things.

1. I needed to sand down the plug just a bit so it would fit into the hole to get a negative reading.

2. I still had a hard time holding the bolt in a consistent manner. So I came up with the iGauge Firing Pin Protrusion Tool:
