Do You Have to Headspace an AR-15?

When it comes to building or maintaining an AR-15 rifle, one question often arises: do you have to headspace it? The answer is not straightforward and depends on various factors. In this detailed guide, we will explore the importance of headspacing, the process of headspacing an AR-15, and the potential consequences of not doing so.

What is Headspacing?

Headspace refers to the distance between the face of the receiver and the bolt face when the bolt is fully closed. It is crucial for ensuring that the cartridge case is properly supported and that the bullet is seated correctly in the chamber. In other words, headspacing ensures that the firearm operates reliably and safely.

Why is Headspacing Important?

Proper headspacing is essential for several reasons:

• Reliability: A firearm with incorrect headspacing may not cycle properly, leading to malfunctions and potential safety hazards.

• Accuracy: Incorrect headspacing can cause the bullet to be seated too far into the case, affecting the bullet’s trajectory and accuracy.

• Chamber Life: Over time, the chamber can wear, causing the headspace to increase. This can lead to reduced accuracy and reliability.

When Do You Need to Headspace an AR-15?

There are several situations where you may need to headspace an AR-15:

• New Build: When building a new AR-15, it is essential to ensure that the headspacing is correct from the start.

• Chamber Wear: If the chamber has worn over time, it may need to be headspaced to maintain proper functioning.

• Barrel Change: When replacing a barrel, it is crucial to check and adjust the headspacing to ensure compatibility with the new barrel.

• After a Gunsmithing Job: If you have had any gunsmithing work done, such as chambering or reaming, headspacing should be checked and adjusted if necessary.

How to Headspace an AR-15

Headspace an AR-15 by following these steps:

1. Secure the rifle in a vise or other stable mounting.

2. Insert a headspace gauge into the chamber, ensuring it is fully seated.

3. Use a torque wrench to tighten the bolt, applying the recommended torque.

4. Remove the bolt and measure the headspace using a headspace gauge.

5. Compare the measured headspace to the manufacturer’s specifications.

6. If the headspace is outside the acceptable range, adjust it using a reamer and a chamfering tool.

7. Repeat the process until the headspace is within the specified range.
