The .223 Wylde chambering is increasingly popular among AR-15 builders and shooters for its versatility, allowing the firing of both .223 Remington and 5.56 NATO ammunition. However, proper headspace is critical for safe and reliable operation. Using a headspace gauge is an essential step in ensuring your .223 Wylde chamber is within specification before you ever load a round. This guide will explain why headspace is so crucial, the different types of gauges available, how to use them, and what to do if you encounter headspace issues.
Understanding Headspace in .223 Wylde
Headspace refers to the distance between the bolt face and the head of the cartridge case when the bolt is fully closed. Too much headspace (excessive headspace) can lead to dangerous malfunctions such as a catastrophic case rupture, potentially causing serious injury. Conversely, too little headspace (short headspace) can cause malfunctions like failure to fire or extract. .223 Wylde's design intends for it to be compatible with both .223 Remington and 5.56x45mm NATO ammunition, but careful headspace measurement is essential given the potential differences between the two cartridges.
Why is Headspace so Important in .223 Wylde?
- Safety: Incorrect headspace is the leading cause of firearm-related injuries. A properly functioning headspace ensures the cartridge case is adequately supported during firing, preventing catastrophic failures.
- Reliability: Proper headspace guarantees reliable feeding, firing, and extraction. Improper headspace can lead to malfunctions, interrupting shooting sessions and potentially causing damage to your firearm.
- Accuracy: While less direct than safety or reliability, consistent headspace contributes to improved accuracy by ensuring consistent cartridge ignition and pressure.
Types of Headspace Gauges for .223 Wylde
Several types of headspace gauges are available, each with its own advantages and disadvantages:
Field Gauges:
These gauges are simple, inexpensive, and easy to use. They typically consist of a "GO" gauge (which should fit easily into the chamber) and a "NO GO" gauge (which should not fit into the chamber). If the "GO" gauge fits and the "NO GO" gauge does not, your headspace is within the acceptable range.
Precision Gauges:
Offering greater accuracy than field gauges, these often include additional gauges for finer headspace measurement. Precision gauges are useful for more critical applications or when fine-tuning chamber dimensions is required.
How to Use a Headspace Gauge
Using a headspace gauge is a straightforward process. Here's a step-by-step guide:
- Clean the chamber: Ensure the chamber of your firearm is thoroughly clean and free from debris. Any obstruction could interfere with accurate headspace measurement.
- Insert the "GO" gauge: Gently insert the "GO" gauge into the chamber. It should slide in smoothly and easily. If it doesn't, there might be an obstruction or a headspace problem.
- Insert the "NO GO" gauge: Attempt to insert the "NO GO" gauge. It should not fit into the chamber. If it does, your headspace is excessive.
- Interpret the results: If the "GO" gauge fits easily and the "NO GO" gauge does not, your headspace is within the acceptable range. If either gauge fits incorrectly, consult a qualified gunsmith.
What to Do if You Have Headspace Issues
If your headspace is out of specification, do not attempt to fire your firearm. Consult a qualified and experienced gunsmith immediately. They have the expertise to diagnose the problem and perform any necessary repairs or adjustments. Attempting to fix headspace issues yourself can be dangerous and may further damage your firearm.
Conclusion
Regularly checking headspace with a high-quality headspace gauge is crucial for the safe and reliable operation of any firearm, especially those chambered in .223 Wylde. It is a simple yet vital step in responsible gun ownership. By understanding headspace and using the appropriate gauge, you can help prevent accidents and ensure many years of safe and enjoyable shooting. Remember, safety should always be your top priority.
