This video provides an in-depth review and range test of a TRIARC 16" AR-15 upper receiver with approximately 3500 rounds fired. The analysis includes a detailed bench inspection with borescope footage, examination of gas port size, BCG, and chamber gauging. At the range, the performance is evaluated through 30-shot group testing with three types of ammunition: PMC 55gr M193, IMI 77gr Razor Core, and Hornady 73gr ELD Match. The video presents velocity data, standard deviation, muzzle energy, and precision metrics, culminating in an A-ZED score for comparison with other AR-15 barrels.
