The Kel-Tec Sub 2000 Gen 2 is a popular pistol-caliber carbine known for its compact design and affordability. However, like any firearm, it's not without its potential issues. This article delves into common Kel-Tec Sub 2000 Gen 2 problems reported by users, offering insights and potential solutions. We'll examine reported malfunctions, reliability concerns, and common areas of user frustration. Understanding these potential problems can help you make an informed decision before purchasing or assist you in troubleshooting if you already own one.
Understanding the Kel-Tec Sub 2000 Gen 2's Design
Before diving into the problems, it's crucial to understand the Sub 2000's unique design. Its innovative folding design and use of Glock magazines contribute to its portability and versatility. However, this innovative design also introduces potential points of failure that are less common in traditional firearms. The use of polymer construction, while reducing weight, can also impact durability and reliability under stress.
Common Kel-Tec Sub 2000 Gen 2 Problems
While many users praise the Sub 2000's value and unique features, several recurring problems have been reported.
1. Feeding Issues and Magazine Problems
One of the most frequently reported issues revolves around feeding problems, often linked to the magazine. The use of Glock magazines, while convenient, can sometimes cause malfunctions. This can manifest as:
- Failure to Feed: The firearm may fail to chamber a round properly. This can be due to magazine issues, weak springs, or even the angle at which the magazine is inserted.
- Double Feeds: Occasionally, the firearm might attempt to feed two rounds simultaneously, resulting in a jam.
- Magazine Wobble: Some users report excessive magazine wobble, impacting feeding reliability.
Solutions: Ensure you are using high-quality Glock magazines, and check for proper magazine seating and spring tension. Consider replacing worn-out magazines.
2. Extraction and Ejection Problems
Extraction and ejection failures are also relatively common. The Sub 2000’s design, while efficient, can sometimes lead to:
- Failure to Extract: Spent casings may fail to eject from the chamber, resulting in a jam.
- Weak Ejection: Spent casings may be ejected weakly, potentially impacting safety or creating follow-up shot difficulties.
Solutions: Cleaning and lubrication are crucial. Ensure that the extractor is properly functioning. A malfunctioning extractor often requires professional repair or replacement.
3. Bolt Issues
While less frequent than feeding issues, problems with the bolt can occur. This might include:
- Bolt Cycling Problems: The bolt may fail to cycle reliably, leading to stoppages.
- Bolt Wear: Over time, the bolt might show wear, particularly on the rails.
Solutions: Thorough cleaning and lubrication are paramount. If the problem persists, it may require professional attention. Regular inspection for wear and tear is recommended.
4. Accuracy Concerns
While not a malfunction, some users report less-than-stellar accuracy compared to other carbines in its class. This is often attributed to:
- Folding Mechanism: The folding design might introduce some flex or instability affecting accuracy.
- Lightweight Construction: The polymer construction can also contribute to perceived reduced accuracy.
Solutions: While the design limitations may not be entirely rectifiable, using high-quality ammunition and practicing proper shooting techniques can help maximize accuracy.
5. Sights and Optics Mounting
Mounting optics or using the iron sights can sometimes present challenges.
- Sight Alignment: The iron sights can prove difficult for some shooters.
- Optics Mounting: While the Sub 2000 offers Picatinny rails, finding an optic that fits perfectly can sometimes be challenging due to the close proximity of the receiver.
Solutions: Choosing the right optic and using quality mounting hardware is critical. Consider a lower-profile optic to avoid interfering with the folding mechanism.
Maintenance and Prevention
Regular maintenance is key to maximizing reliability and longevity of your Sub 2000 Gen 2. This includes:
- Cleaning: Clean your firearm regularly after each range trip. Use a quality gun cleaning kit and appropriate solvents.
- Lubrication: Apply a suitable gun lubricant to all moving parts.
- Inspection: Regularly inspect for any signs of wear, damage, or loose parts.
Conclusion: Weighing the Pros and Cons
The Kel-Tec Sub 2000 Gen 2 is a unique and affordable pistol-caliber carbine. However, understanding its potential problems is crucial. While many users experience excellent reliability, the potential for feeding, extraction, and other issues should be considered. Through proper maintenance, and by addressing the issues mentioned above promptly, you can enhance its reliability and enjoy the benefits of this innovative firearm. Remember, always practice safe gun handling and seek professional help if you encounter persistent problems beyond your expertise.
