How Consistent Are Daniel Defense AR-15 Barrels? Accuracy & Measurements Compared
This video investigates the consistency of Daniel Defense AR-15 barrels by comparing two identical 16" lightweight, cold hammer-forged barrels. The analysis includes a detailed physical inspection with measurements of key dimensions (barrel extension diameter, gas block journal, gas port diameter) and a borescope examination of the rifling, gas port, and crown. This is followed by a practical accuracy test involving 30-shot groups at 100 yards with various ammunition types. Muzzle velocity, standard deviation, and extreme spread are measured using a chronograph to assess performance differences. The video aims to determine if minor manufacturing variances lead to noticeable performance differences in otherwise identical barrels.
