This guide details how to check headspace on an AK rifle using 'go' and 'no-go' gauges, as demonstrated by Colton Sons, an AK Engineer at Palmetto State Armory. Proper headspace ensures safe operation and optimal rifle life. The video emphasizes using hand pressure only when closing the bolt on gauges and explains PSA's tight factory tolerances for new firearms.

Quick Summary

Checking headspace on an AK rifle involves using 'go' and 'no-go' gauges. A 'go' gauge must close with hand pressure, indicating minimum safe headspace. A 'no-go' gauge must not close, ensuring headspace doesn't exceed maximum safe limits. Palmetto State Armory sets new rifles tight for longevity.

Frequently Asked Questions

What is headspace and why is it important for an AK rifle?

Headspace is the distance between the bolt face and the chamber's locking surface. Proper headspace is crucial for safe firearm operation, preventing case ruptures or failures to extract. It ensures the cartridge is correctly supported when fired.

How do I check headspace on my AK using go and no-go gauges?

Ensure the rifle is unloaded. Insert a 'go' gauge and gently close the bolt with hand pressure. If it closes, headspace is within minimum limits. Then, insert a 'no-go' gauge and attempt to close the bolt. If it does not close, headspace is within maximum safe limits.

What headspace gauge sizes does Palmetto State Armory use?

Palmetto State Armory (PSA) uses Pacific Tool and Gauge (PTG) gauges. While consumers often buy 'go' (1) and 'no-go' (7), PSA uses a '4' as their internal 'no-go' standard for tighter factory tolerances on new rifles.

Is it normal for a new AK to be tight when checking headspace?

Yes, it is normal and desirable for new AK rifles from Palmetto State Armory to be set very tight on the 'go' gauge. This tight tolerance is intentional to maximize the rifle's service life and ensure reliability over time.
