The Kel-Tec Sub 2000 Gen 2 is a popular pistol-caliber carbine known for its unique folding design and affordability. However, like any firearm, it's not without its potential issues. This guide delves into common Kel-Tec Sub 2000 Gen 2 problems, offering insights into troubleshooting and preventative maintenance. We'll explore both reported issues and potential solutions, helping you to understand and address any concerns you might have with your firearm.
Common Kel-Tec Sub 2000 Gen 2 Issues
While generally reliable, several recurring problems have been reported by Sub 2000 Gen 2 owners. These issues aren't necessarily indicative of a faulty firearm, but understanding them is crucial for responsible ownership and maintenance.
1. Feeding and Ejection Problems
One of the most frequently discussed issues involves feeding and ejection. This can manifest in several ways:
- Failure to Feed: This often stems from issues with magazine compatibility, ammunition type, or improper lubrication. Using the correct magazine and high-quality ammunition is crucial. Insufficient lubrication can also hinder smooth feeding.
- Failure to Eject: Spent casings may fail to eject completely, leading to jams. This can be caused by insufficient gas pressure, dirty firearm components, or again, a lack of lubrication.
Troubleshooting: Start by ensuring you are using the correct magazines for your caliber. Try different types of ammunition. Clean and lubricate the firearm thoroughly, paying particular attention to the bolt, chamber, and ejection port. If problems persist, consider seeking professional gunsmith assistance.
2. Magazine Issues
Kel-Tec Sub 2000 Gen 2 magazines, while generally reliable, have occasionally been reported to exhibit problems:
- Magazine Wobble: Some users report excessive magazine wobble, potentially impacting feeding reliability.
- Magazine Failure: In rare cases, magazines may experience breakage or failure to properly lock into the firearm.
Troubleshooting: Inspect your magazines for damage. Ensure they are correctly seated in the firearm. If wobble persists, consider replacing the magazine. For consistent magazine failure, contact Kel-Tec customer service or consult a qualified gunsmith.
3. Folding Mechanism Problems
The Sub 2000's folding mechanism is a key feature, but it's also a potential source of issues:
- Loose Folding Mechanism: Over time, the folding mechanism may become loose, potentially affecting the firearm's stability and accuracy when folded or unfolded.
- Mechanism Failure: In rare cases, the folding mechanism may malfunction completely, preventing the firearm from folding or unfolding properly.
Troubleshooting: Regularly inspect the folding mechanism for any signs of looseness or damage. If looseness is detected, consider tightening or replacing any loose components. If the mechanism fails completely, seek professional assistance.
4. Accuracy Issues
While not inherently a "problem," some users report less-than-stellar accuracy with the Sub 2000 Gen 2, especially at longer ranges. This is typically due to the firearm's design and the inherent limitations of pistol-caliber carbines.
Troubleshooting: Focus on proper shooting technique, use high-quality ammunition, and consider upgrading the sights or adding an optic to improve accuracy.
Preventative Maintenance for Your Kel-Tec Sub 2000 Gen 2
Regular cleaning and lubrication are vital to maintain the reliability and longevity of your Sub 2000 Gen 2. Follow the manufacturer's instructions for cleaning and lubrication, paying particular attention to:
- Bolt: Keep the bolt clean and well-lubricated.
- Ejection Port: Ensure the ejection port is free from debris.
- Magazine Well: Regularly clean the magazine well to prevent feeding issues.
- Folding Mechanism: Lubricate the folding mechanism to ensure smooth operation.
Conclusion
The Kel-Tec Sub 2000 Gen 2, despite occasional reported problems, remains a popular and versatile firearm. By understanding the potential issues, implementing preventative maintenance, and properly troubleshooting minor problems, you can ensure the reliable operation of your firearm. Remember that responsible gun ownership involves regular cleaning, proper maintenance, and understanding the limitations of your firearm. If significant problems persist, always seek professional assistance from a qualified gunsmith.
