The CMMG .22LR conversion kit is a popular choice for AR-15 owners looking for affordable and convenient plinking or training. However, like any firearm accessory, it can occasionally present issues. This guide will address common CMMG .22 conversion kit problems, offering troubleshooting steps and potential solutions to get you back on the range.
Common CMMG .22 Conversion Kit Problems
Several issues can arise with CMMG .22LR conversion kits. These range from simple malfunctions to more complex problems requiring deeper investigation. Let's break down some of the most frequently reported problems:
1. Failure to Feed/Feed Malfunctions
This is arguably the most common complaint. Failure to feed can stem from several sources:
- Magazine Issues: Bent or damaged magazines are a frequent culprit. Inspect your magazines carefully for any imperfections. Try different magazines to rule out a magazine-specific problem. Ensure the magazine is properly seated in the conversion kit.
- Ammunition Issues: Different brands and types of .22LR ammunition can perform differently. Try using a different brand or type of ammunition to see if this resolves the issue. Low-quality or improperly lubricated ammo is a common cause.
- Bolt Issues: The bolt may not be cycling properly. Ensure it's clean and lubricated. Look for any signs of damage or wear.
- Improper Installation: Double-check the installation of the conversion kit following the manufacturer's instructions meticulously. A slight misalignment can cause feeding problems.
2. Failure to Eject
Spent casings failing to eject can also lead to malfunctions. Potential causes include:
- Dirty or Damaged Ejection Port: A buildup of residue in the ejection port can impede proper ejection. Thoroughly clean this area.
- Weak or Damaged Extractor: The extractor is responsible for pulling the spent casing from the chamber. Inspect it for damage or wear.
- Improper Gas Block Setting (if applicable): Some conversion kits might require specific gas block adjustments. Check your instruction manual for any gas block settings recommendations.
- Ammunition Issues (Again): Certain ammunition types might not have sufficient energy for reliable ejection. Try using a different brand or type.
3. Jams and Misfires
Jams can be caused by various factors, often intertwined with feeding and ejection problems:
- Double Feeds: The gun tries to feed two rounds simultaneously. This usually points to magazine or feeding mechanism issues.
- Squib Loads: A squib load is a cartridge that fails to fully detonate. This can cause a dangerous situation; carefully clear the firearm according to manufacturer instructions if you encounter a squib load.
- Ammunition Issues (Once More): Low-quality or damaged ammunition is a significant contributor to jams.
4. Accuracy Issues
While not always a malfunction, poor accuracy can be a frustrating problem.
- Sight Alignment: Ensure your sights are properly aligned and zeroed.
- Ammunition Consistency: Use high-quality, consistent ammunition for improved accuracy.
- Barrel Condition: A dirty or damaged barrel can negatively impact accuracy.
Troubleshooting Steps
Before contacting CMMG customer support, try these troubleshooting steps:
- Clean your firearm thoroughly. This is often the simplest solution to many problems.
- Inspect all components carefully for signs of damage or wear.
- Use different ammunition. Experiment with different brands and types of .22LR to identify compatibility issues.
