Duration: 3:43

This video details the professional manufacturing process of Daniel Defense barrels, from raw 4150 ordnance grade steel to finished components. It highlights the critical cold hammer forging technique, emphasizing the precision required, the immense forces involved (50 tons), and the maintenance of specialized forging equipment. The process includes gun-drilling, honing, mandrel insertion, and CNC machining for specific profiles like M4 and Government.

Quick Summary

Daniel Defense manufactures its barrels using 4150 ordnance grade steel through a cold hammer forging process. This method employs four hammers delivering 50 tons of force to shape the chamber and rifling around a mandrel. Barrels are then CNC machined into profiles like M4, Government, or Lightweight, with forging hammers requiring maintenance every 1,000 parts.
