Creedmoor Sports Firing Pin Protrusion Gauge
The Creedmoor Sports Firing Pin Protrusion Gauge allows you to quickly and accurately measure how far the firing pin protrudes from the breech face when it is in its forwardmost position. This will help you identify potential causes of light primer strikes and misfires and avoid potential pierced primers due to excess firing pin protrusion. The Firing Pin Protrusion Gauge is precision machined from Stainless Steel to ensure accurate measurements and works for all types of actions including most ARs and Bolt Guns
