This Brownells Quick Tip video provides a clear, industry-standard method for accurately measuring firearm barrel length, guided by Caleb. It covers both traditional firearms and specific platforms like the AR-15 and Henry .22 lever-action. Essential tools like a cleaning rod, tape measure, and Sharpie are demonstrated. The video is structured with chapters for easy navigation, from introduction to a recap and outro.
This video demonstrates how to measure headspace on a bolt-action rifle, a crucial aspect of firearm safety. Larry Potterfield, Founder and CEO of MidwayUSA, uses a Mauser 98 as an example. The process involves removing the bolt and extractor, then using Go and No-Go gauges to check if the chamber has the correct amount of headspace. The video emphasizes that if the bolt closes completely on a No-Go gauge, the headspace is excessive and the firearm should not be fired. It highlights the importance of proper tools and procedures for this gunsmithing task.
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.
This video provides a detailed gunsmithing guide on accurately measuring shotgun bore diameter and barrel wall thickness. Larry Potterfield, Founder and CEO of MidwayUSA, demonstrates the essential tools and techniques for taking these critical measurements. The video specifically highlights the use of a Skeet's Bore Gage for bore diameter and a Newboult and Thorpe Barrel Wall Thickness Gage for barrel wall thickness. It's a valuable resource for anyone involved in shotgun maintenance, modification, or gunsmithing.
