This video features a head-to-head comparison of two BCM BFH ELW (Enhanced Lightweight) AR-15 barrels. The creator conducts thorough inspections, including borescoping and headspace checks, revealing some unexpected findings. The testing involves shooting 30-shot groups at 100 yards with three different ammunition types: Winchester 55gr M193 FMJ, Frontier 68gr BTHP, and Federal Gold Medal 77gr SMK. Data is collected using a Garmin Zero C1 Pro chronograph and a Mantis X10 Elite, with results analyzed using mean radius and a custom A-ZED scoring system. The video aims to determine the consistency and real-world accuracy of these specific barrel models and whether any bore anomalies correlate with performance.
