DDI Hammer Forged AK47S, 1000 Rounds Later...Resurrection?

Published on November 20, 2016
Duration: 14:47

This video details the post-1000 round inspection of a DDI Hammer Forged AK47S, focusing on the critical failure of the original extractor. The presenter demonstrates the process of replacing the extractor and bolt, and crucially, performs a headspacing test with new DDI bolts to verify their 'drop-in' claim. The inspection reveals wear on the trunnion and bolt carrier, but the new extractor and bolts appear to be holding up well, with headspacing confirmed as correct on new components.

Quick Summary

The DDI Hammer Forged AK47S experienced a critical extractor failure after an unspecified number of rounds. DDI provided replacement parts, including a new extractor and ten new bolts. Testing confirmed that new DDI bolts are correctly headspaced and function as drop-in replacements without requiring manual adjustments.

Frequently Asked Questions

What critical failure did the DDI AK47S experience?

The DDI AK47S experienced a critical failure when its original extractor snapped, preventing it from being eligible for a 5,000-round survivalist sticker. This necessitated replacement of the extractor and further testing.

How did DDI address the extractor failure on the AK47S?

DDI provided a new extractor and ten new, unassembled bolts for the AK47S. This allowed the testing to continue and verify the performance of replacement parts.

What modifications were made to the DDI AK47S during testing?

The original polymer furniture was replaced with a wood stock. A Khyber Customs cheese grater handguard and a VG6 Epsilon muzzle device were installed to improve ergonomics and recoil management.

Are new DDI bolts drop-in replacements for headspacing?

Yes, testing with new DDI bolts and a no-go gauge confirmed that they are correctly headspaced and function as drop-in replacements, meaning they do not require manual headspacing adjustments.
