5.56 No Go Gauge Guide

Introduction to the 5.56 No Go Gauge

The 5.56 No Go Gauge is a crucial tool for anyone who owns or uses a 5.56mm rifle, particularly those in military or law enforcement contexts. This gauge is designed to ensure that the rifle’s chamber is within the acceptable specifications for safe and reliable functioning. In this blog post, we will delve into the world of the 5.56 No Go Gauge, exploring its purpose, how it works, and why it’s essential for maintaining the health and reliability of your firearm.

What is a No Go Gauge?

A No Go Gauge is a tool used to check the chamber of a firearm to ensure that it is not oversized or otherwise out of specification. The gauge is inserted into the chamber, and if it goes in too easily or too far, it indicates that the chamber may be worn or damaged, potentially leading to reliability issues or even safety hazards. The No Go Gauge is an essential part of maintaining any firearm, but it’s particularly critical for rifles like the 5.56mm, which are often used in high-stress environments.

How Does the 5.56 No Go Gauge Work?

The 5.56 No Go Gauge works by simulating the dimensions of a cartridge that is at the maximum allowable size for the 5.56mm chamber. By attempting to insert this gauge into the chamber, the user can determine if the chamber is within the acceptable size limits. If the gauge does not fit or fits too easily, it indicates that the chamber may be oversized, which could lead to issues such as: - Case head separation: Where the cartridge case separates from the bullet upon firing, potentially causing damage to the firearm or injury to the user. - Increased wear: An oversized chamber can lead to accelerated wear on the firearm’s components, reducing its lifespan and reliability. - Reduced accuracy: A chamber that is not within specifications can affect the consistency of cartridge seating, leading to reduced accuracy and potentially dangerous situations.

Using the 5.56 No Go Gauge

Using the 5.56 No Go Gauge is a straightforward process that requires attention to detail and adherence to proper procedures. Here are the steps to follow: - Ensure the rifle is unloaded and safe to handle. - Insert the No Go Gauge into the chamber, aligning it with the chamber’s axis. - Gently push the gauge into the chamber until it stops. If it does not stop or goes in too easily, this indicates a potential issue with the chamber size. - Repeat the process several times to ensure consistency in the results.

📝 Note: It's crucial to follow the manufacturer's instructions for the specific No Go Gauge you are using, as different models may have slightly varying procedures.

Common Issues and Troubleshooting

If the No Go Gauge indicates a potential issue with your rifle’s chamber, it’s essential to address the problem promptly. Here are some common issues and troubleshooting steps: - Oversized chamber: If the gauge goes in too easily, it may indicate an oversized chamber. In this case, consider having the rifle inspected and potentially rechambered by a professional gunsmith. - Worn or damaged components: If the gauge does not fit or fits inconsistently, it could indicate worn or damaged components within the rifle. Again, professional inspection and repair are recommended.
