AK Headspacing: No Go/Go/Field..?

Published on December 28, 2018
Duration: 10:33

This guide details the proper procedure for checking AK headspacing using go, no-go, and field gages, as demonstrated by Rob Ski and Chase Sisgold. It emphasizes correct techniques for both manufacturing and field checks, highlighting the critical importance of not forcing gages and understanding the safety implications of improper headspacing. Expert advice is provided on when to seek professional gunsmithing services.

Quick Summary

Proper AK headspacing is checked using go, no-go, and field gauges. A 'go' gage confirms operational closure, while a 'no-go' gage indicates excessive headspace if the bolt closes on it. Closing on a 'field' gage means the firearm is unsafe. Never use excessive force during checks, as it can damage the barrel. Consult a gunsmith for any issues.

Frequently Asked Questions

What are the different types of AK headspace gauges and what do they indicate?

The primary AK headspace gauges are 'go', 'no-go', and 'field'. A 'go' gage confirms the bolt closes within operational limits. A 'no-go' gage indicates if the headspace exceeds the maximum safe limit, and closing on it is a serious issue. A 'field' gage represents the absolute maximum wear limit, and closing on it signifies the firearm is unsafe.

What is the correct procedure for checking AK headspace in the field?

For field checks with an assembled bolt, snap the go gage under the extractor claw. The bolt's locking lug should contact the rail on the right side. For no-go gage checks, the bolt should start to turn but not fully close or contact the rail. Never use excessive force.

When should I seek a gunsmith for AK headspace issues?

If your AK closes on a no-go gage, it's a significant red flag and you should immediately seek an experienced gunsmith. This can indicate other problems beyond just headspace, potentially leading to misfires or dangerous malfunctions.

Can using excessive force damage my AK when checking headspace?

Yes, absolutely. Slamming the bolt carrier home or forcing a headspace gauge can damage the barrel, as barrels are made of softer material than hardened tool steel gauges. Always use light, controlled pressure for accurate readings and to prevent damage.
