Duration: 27:06

This DDI factory tour highlights their commitment to US-made AK rifles, transitioning from parts kits to in-house manufacturing of receivers and components. They employ advanced techniques like Fenocite nitriding and hammer forging for improved durability and accuracy, coupled with rigorous quality control. Every rifle is test-fired and zeroed, addressing common AK sight alignment issues.

Quick Summary

DDI addresses common AK sight alignment issues by test-firing and zeroing every rifle at their Tennessee facility. They utilize Fenocite nitriding for barrels and internals, arguing it preserves accuracy better than chrome lining by avoiding added layers that can enhance imperfections.

Frequently Asked Questions

What makes DDI's AK rifles unique in their manufacturing process?

DDI focuses on US-made components, using 4140 steel for receivers and Green Mountain barrels treated with Fenocite nitriding. They also employ advanced techniques like hammer-forged receivers and rigorous quality control, ensuring every rifle is test-fired and zeroed.

How does DDI's Fenocite finishing differ from traditional chrome lining?

DDI's Fenocite, a form of ferritic nitrocarburizing, is applied directly to the metal. Unlike chrome lining, it doesn't add layers that can potentially enhance imperfections, aiming to preserve accuracy while providing excellent durability and corrosion resistance.

What quality control measures does DDI implement in their AK production?

DDI performs rigorous quality control on all parts, including surplus components. They reportedly reject about 15% of front trunnions due to inconsistencies and ensure every finished rifle is test-fired and zeroed for straight sight alignment.

What are the key US-made components DDI manufactures for their AKs?

DDI manufactures receivers from solid 4140 steel, including innovative hammer-forged milled receivers. They also produce their own AK-74 style trunnions and bolts in Tennessee, ensuring tighter tolerances and higher quality control.
