Go No Go Gauge 5.56 Calibration Guide

Introduction to Go No Go Gauges

The Go No Go gauge, also known as a GO/NOGO gauge, is a type of gauge used to check if a part is within specified limits. It is commonly used in the manufacturing industry to ensure that parts meet the required specifications. In the context of firearms, a Go No Go gauge is used to check the chamber of a rifle to ensure that it is safe to fire. In this article, we will focus on the 5.56 Go No Go gauge and provide a step-by-step guide on how to calibrate it.

Understanding the 5.56 Go No Go Gauge

The 5.56 Go No Go gauge is specifically designed for the 5.56x45mm NATO cartridge, which is commonly used in AR-15 rifles. The gauge consists of two parts: the GO gauge and the NOGO gauge. The GO gauge is used to check if the chamber is within the minimum acceptable limits, while the NOGO gauge is used to check if the chamber is within the maximum acceptable limits.

Importance of Calibration

Calibration of the 5.56 Go No Go gauge is crucial to ensure that it is accurate and reliable. Inaccurate measurements can lead to unsafe conditions, such as a chamber that is too large or too small, which can cause the rifle to malfunction or even explode. Therefore, it is essential to follow the calibration process carefully to ensure that the gauge is accurate and reliable.

Calibration Process

The calibration process involves several steps, which are outlined below: * Step 1: Preparation: Before starting the calibration process, ensure that the gauge is clean and free from any debris or obstructions. * Step 2: Insertion: Insert the GO gauge into the chamber, making sure that it is fully seated. * Step 3: Measurement: Measure the distance between the gauge and the chamber, using a precision measuring instrument. * Step 4: Verification: Verify that the measurement is within the acceptable limits, as specified in the manufacturer’s instructions. * Step 5: NOGO Gauge: Repeat the process using the NOGO gauge, ensuring that it does not fit into the chamber.

Gauge Type	Acceptable Limits
GO Gauge	1.4636 - 1.4646 inches
NOGO Gauge	1.4706 - 1.4716 inches

Troubleshooting Common Issues

During the calibration process, you may encounter some common issues, such as: * Gauge not fitting: Check that the gauge is clean and free from debris. Also, ensure that the chamber is clean and free from obstructions. * Inaccurate measurements: Check that the measuring instrument is accurate and calibrated correctly. * Gauge damaged: Inspect the gauge for any damage or wear. If damaged, replace the gauge with a new one.

💡 Note: Always follow the manufacturer's instructions for calibration and maintenance of the 5.56 Go No Go gauge.

Maintenance and Storage

To ensure that the 5.56 Go No Go gauge remains accurate and reliable, it is essential to follow proper maintenance and storage procedures. This includes: * Cleaning: Regularly clean the gauge to prevent debris and obstructions from accumulating. * Storage: Store the gauge in a dry, cool place, away from direct sunlight and moisture. * Calibration checks: Regularly check the gauge for accuracy and calibration, to ensure that it remains reliable.

As we near the end of this guide, it’s essential to summarize the key points and takeaways. The 5.56 Go No Go gauge is a critical tool for ensuring the safety and reliability of firearms. By following the calibration process and maintenance procedures outlined in this article, you can ensure that your gauge remains accurate and reliable. Remember to always follow the manufacturer’s instructions and take necessary precautions when handling firearms.
