This video demonstrates four distinct methods for measuring and checking the firing pin protrusion on an AR-15 platform rifle. Understanding correct firing pin protrusion is crucial for reliable ignition and safe firearm operation. The content focuses on practical gunsmithing techniques applicable to AR-15 owners and maintainers.
This video by Larry Potterfield of MidwayUSA demonstrates how to precisely measure firing pin protrusion on a bolt-action rifle, specifically using a Model 98 Mauser. He outlines the process of removing the bolt, dropping the striker, and utilizing a Baker firing pin protrusion gauge and calipers. The technique involves zeroing the gauge, placing it on the bolt face, locking it, and then measuring the gauge with calipers. By subtracting the initial width of the gauge at zero, the exact firing pin protrusion is determined. The video emphasizes a practical, step-by-step approach to this critical gunsmithing measurement.
