AR-15 Misfire Troubleshooting - Disassembly to Find the Solution
Misfires can be incredibly frustrating, especially when your AR-15 fails to fire after assembly or adding new attachments. For a new shooter with limited experience, this can be intimidating and confusing. Fortunately, troubleshooting misfires can often be resolved with a systematic approach to identify and address the underlying issues. Learn more from RailScales on all things AR-15s now!
Common Reasons for an AR-15 Misfire
Understanding the common causes of an AR-15 misfire can help in efficiently troubleshooting and restoring functionality. Here are a few typical reasons:
1. Poor Assembly
- Misalignments or improper assembly, particularly in the bolt carrier group (BCG) or lower receiver, can lead to misfires. A small mistake like an improperly seated firing pin or loose bolt can prevent the rifle from cycling properly.
2. Faulty Firing Pin or Worn Parts
- Over time, firing pins and springs wear out, leading to light primer strikes or failure to fire. Regular maintenance and replacing worn-out parts are essential for ensuring consistent performance.
3. Dirty Chamber or BCG
- Carbon buildup and debris can block or obstruct parts within the chamber or bolt carrier group, causing the AR-15 to jam or misfire. Regular cleaning is essential to maintain performance.
4. Magazine Issues
- Faulty or incompatible magazines can prevent rounds from being chambered correctly. Make sure your magazine is properly seated and fits the receiver correctly.
5. Ammunition Issues
- Poor-quality or incompatible ammunition can lead to frequent misfires. Ensure you’re using the correct caliber and quality ammunition that’s compatible with your AR-15.
6. Environmental Factors
- Extreme cold, dirt, or moisture can cause parts to freeze, corrode, or malfunction, particularly if the AR is exposed to the elements over time.
Why Misfire Issues Can Be Critical
In critical situations, such as self-defense or hunting, a misfire could be detrimental. Ensuring your AR-15 functions reliably is essential for safety, performance, and preparedness. Regular testing and range practice can help prevent these issues from arising during critical moments.
How to Disassemble an AR-15 with Attachments for Troubleshooting
For a new shooter or an AR-15 owner with limited knowledge, following a step-by-step guide on disassembly and troubleshooting can be very helpful.
1. Safety First
- Ensure your AR-15 is unloaded, with the magazine removed and the chamber empty.
- Point the rifle in a safe direction and engage the safety.
2. Remove Attachments
- Detach any accessories like optics, lights, or foregrips that could obstruct disassembly.
- This makes it easier to access internal components and identify potential issues.
3. Field Strip the Rifle
- Separate the upper and lower receivers.
- Remove the bolt carrier group and charging handle from the upper receiver.
- Take out the firing pin, cam pin, and bolt from the bolt carrier group.
4. Inspect Key Components
- Check the firing pin for wear or damage, and ensure it moves freely.
- Examine the bolt, particularly the extractor and gas rings, for any wear or missing parts.
- Inspect the buffer tube and spring for wear or misalignment.
5. Reassemble Carefully
- Reassemble the parts, ensuring everything is properly aligned and seated.
- Test the components to ensure smooth movement and functionality before reattaching any accessories.
6. Test Firing
- After reassembly, take the AR-15 to the range and test fire to ensure the issue is resolved.
- Check each shot for consistency and functionality.
Alternative Solutions if Errors Persist
If disassembly and basic troubleshooting don’t resolve the misfire issue, here are a few additional steps to consider:
1. Replace Worn Parts
- Worn parts, especially in the firing mechanism, should be replaced with quality components.
2. Consult a Gunsmith
- For persistent issues, consult a professional gunsmith who can diagnose and repair internal problems.
3. Consider Upgrading to Quality Attachments
- Low-quality parts or accessories can sometimes cause alignment or function issues. Upgrading to quality parts from reputable brands can improve reliability.
