Proof Research 16” AR-15 Barrel – The Best Yet? (30-Shot Group Tests)
This YouTube video features an in-depth review and testing of a 16-inch Proof Research AR-15 barrel. The analysis includes borescope inspection, gauging, and extensive 30-shot group tests at 100 yards using various ammunition types, including Winchester 55gr M193, IMI Razor Core 77gr, Federal Gold Medal 77gr, and Black Arc NAS3 262 Alpha 77gr. Key performance metrics like A-ZED score, velocity, SD, rifle stability, and group size are captured. The review highlights unusual tool marks in the chamber and throat and assesses their impact on the barrel's performance, noting a record-breaking M193 group and strong results across all 77gr loads.
