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

Published on December 28, 2018
Duration: 10:33

This guide details how to check AK headspacing using go, no-go, and field gauges, as demonstrated by experts Rob Ski and Chase Sisgold. It emphasizes proper technique, the importance of not using excessive force, and identifying signs of wear that indicate a need for gunsmith attention. Proper headspacing is crucial for safe and reliable firearm function.

Quick Summary

Checking AK headspacing involves using go, no-go, and field gauges. A 'go' gauge confirms minimum acceptable headspace, while a 'no-go' gauge verifies the maximum safe limit. Closing on a 'no-go' gauge is unsafe and requires gunsmith attention. Always use light pressure during checks to avoid damaging the firearm.

Frequently Asked Questions

What are the main headspacing standards for firearms?

The two primary headspacing standards are CIP, used in Europe, and SAAMI, used in the United States. While they have differences, gauges from either standard are generally usable on both US-made and foreign-made AKs due to minimal variations.

How do you properly check AK headspacing with a no-go gauge?

Insert the no-go gauge into the chamber. The bolt should begin to turn but should not fully close or make contact with the rail. Crucially, only apply light pressure; avoid slamming the bolt carrier home, as this can damage the barrel.

What are the risks of incorrect AK headspacing?

Incorrect headspacing, particularly excessive headspace, can lead to dangerous conditions such as misfires or out-of-battery detonations. In severe cases, components like the dust cover could be ejected forcefully.

Can a rifle that closes on a no-go gauge still be safe to fire?

No, a rifle closing on a no-go gauge indicates excessive headspace and is unsafe to fire. This condition requires immediate attention from a qualified gunsmith to prevent potential malfunctions or dangerous failures.
