The CMMG .22 LR conversion kit offers a compelling way to enjoy affordable plinking and training with your AR-15 platform. However, like any firearm accessory, it's not immune to issues. This guide dives deep into common CMMG .22 LR conversion kit problems, providing troubleshooting steps and potential solutions to get you back on the range.
Common CMMG .22 LR Conversion Kit Problems
Several factors can contribute to malfunctions with your CMMG .22 LR conversion kit. Let's explore the most frequently reported issues:
1. Feeding Problems: Stovepipes, Misfeeds, and Failure to Feed
This is arguably the most common complaint. Issues with feeding often stem from:
- Magazine Issues: Low-quality or improperly seated magazines are frequent culprits. Ensure you're using CMMG-branded magazines designed specifically for the conversion kit. Damaged or worn magazines will also cause feeding issues. Inspect your magazines for any damage or wear.
- Ammunition Issues: The type and quality of .22 LR ammunition significantly impact reliability. Use high-quality, clean ammunition from reputable manufacturers. Avoid using ammunition with a damaged or inconsistent casing. Variations in bullet weight and shape can also affect feeding. Experimenting with different brands may reveal a preference your kit has.
- Bolt Issues: A dirty or improperly lubricated bolt can hinder smooth feeding. Regular cleaning and proper lubrication are crucial. Ensure the bolt is properly installed and functioning correctly.
- Improper Installation: Double-check that the conversion kit is correctly installed per the manufacturer's instructions. Even a slightly misaligned component can lead to feeding failures.
2. Extraction and Ejection Problems: Failure to Extract, Double Feeds
Issues with extracting and ejecting spent casings often relate to:
- Extractor Problems: The extractor may be worn, damaged, or improperly installed. Inspect the extractor for wear or damage and ensure it's correctly seated.
- Ejector Problems: Similar to the extractor, a damaged or improperly installed ejector can lead to malfunctions. Inspect and ensure proper installation.
- Ammunition Issues: Again, the quality of the ammunition plays a crucial role. Using low-quality ammunition can result in cases that are difficult to extract.
- Bolt Issues: A dirty bolt, again, can contribute. Clean and lubricate as needed.
3. Failure to Fire: Light Strikes or No Strikes
This issue indicates a problem with the firing pin or the ammunition:
- Firing Pin Issues: A broken, bent, or improperly installed firing pin will prevent the cartridge from firing. Carefully inspect the firing pin.
- Ammunition Issues: Primers that are too hard or too soft can also cause failure to fire issues. Using a different brand of ammunition may help determine if this is the cause.
- Improper Trigger Function: Make sure your trigger mechanism in your AR-15 is functioning correctly and not interfering with the conversion kit.
Troubleshooting Steps
- Clean and Lubricate: Before attempting any other troubleshooting, meticulously clean and lubricate your CMMG conversion kit and the host AR-15. Use a high-quality gun cleaning solvent and lubricant suitable for firearms.
- Inspect Ammunition: Carefully inspect your .22 LR ammunition for any damage, defects, or inconsistencies.
- Check the Magazines: Examine your magazines for damage or wear. Try different magazines if available.
- Verify Installation: Double-check that the conversion kit is installed correctly according to the manufacturer's instructions.
- Inspect Components: Carefully examine all components of the conversion kit, including the bolt, extractor, and ejector, for damage or wear.
- Test Different Ammunition: Use different brands and types of .22 LR ammunition to see if that solves the problem.
