This video provides a detailed physical inspection of two Salient Arms International Bolt Carrier Groups (BCGs). The instructor, with clear expertise in firearm components, meticulously gauges and examines various aspects of the BCGs, including headspace, extractor fit, gas key dimensions, firing pin protrusion, and internal finish. Several issues are identified, such as oversized gas keys, potential extractor problems, a failed firing pin hole gauge, and significant internal machining marks, highlighting potential quality control concerns with these specific units.

This guide details how to measure firing pin protrusion on a bolt-action rifle, a critical step for ensuring reliable ignition and preventing primer piercing. The process, demonstrated by Larry Potterfield of MidwayUSA, involves using a specialized gauge and digital calipers to obtain precise measurements. Proper protrusion is essential for safe and effective firearm function.
