Understanding the nuances of these challenges will help you maximize your enjoyment and ensure safe and reliable operation of your Sub 2000.
Feeding and Extraction Issues
At the heart of the shooting experience is the smooth functioning of the feeding and extraction cycle. Problems here are particularly frustrating. One of the more common difficulties is a failure to feed (FTF). This can manifest in different ways: the round may fail to chamber completely, the bolt may jam before closing, or the round may get stuck on the feed ramp. Related to this, failure to extract (FTE) and failure to eject (FTEj) can also occur. In an FTE, the spent casing doesn’t leave the chamber, leading to jams. With FTEj, the spent case might be sluggish or fail to leave the weapon at all, also causing the same issues.
The causes of these feeding and extraction issues are multifaceted. Magazine problems are often a primary culprit. Old, worn, or poorly manufactured magazines can fail to feed rounds correctly, causing a jam. The ammunition itself also plays a crucial role. Certain bullet profiles, the overall length of the loaded round (OAL), or simply the quality of the ammunition can influence whether the Sub 2000 feeds reliably. Ammunition that is not within the correct specifications can be more prone to issues. The Sub 2000 is designed to function with a range of ammunition, but certain brands or loads may be more prone to causing problems.
Extractor issues are also a possibility. The extractor is the small part that grabs the casing of the spent round, pulling it out of the chamber. If the extractor is worn, damaged, or doesn’t have a good grip, it might not be able to perform its function correctly, thus resulting in FTEs. Furthermore, chamber issues, such as roughness, debris, or being slightly out of dimensional specification can impede extraction. The recoil spring, which helps the bolt cycle, must be within the right parameters to extract and eject casings correctly. A weak or worn spring may not provide enough force. Finally, something as simple as improper grip (sometimes referred to as limp wristing) can contribute to feeding and extraction problems. The shooter must be able to handle the rifle recoil, as improper grip can cause the Sub 2000 to malfunction.
Troubleshooting feeding and extraction problems involves a systematic approach. Begin by testing different magazines, ensuring that they are clean and in good working order. A different magazine brand can solve issues with cycling. Next, experiment with different types of ammunition, paying attention to bullet profile and overall length. Consider cleaning the chamber meticulously to remove any fouling. Inspect the extractor for damage or wear, and consider replacing it if necessary. If you suspect a spring issue, consider inspecting and replacing your recoil spring. Finally, check your shooting grip and stance, making sure you’re firmly supporting the firearm.
Trigger and Firing Pin Issues
The trigger mechanism and firing pin are vital for reliable ignition. Problems with these components can significantly hinder the Sub 2000’s function. Trigger malfunctions can range from a heavy trigger pull to the trigger not resetting properly. In more serious cases, the trigger may not engage the firing pin at all. Light primer strikes, where the firing pin doesn’t hit the primer hard enough to ignite the round, are another common problem. This can be caused by a weakened firing pin spring or by debris interfering with the firing pin’s movement. Other issues can occur with firing pin issues, or problems with its spring.
The root causes of these trigger and firing pin problems are varied. Wear and tear on the trigger components, particularly after prolonged use, can lead to malfunctions. Improper maintenance or a lack of lubrication can also hinder smooth trigger operation. Damage to any part of the trigger assembly could also create issues. Additionally, ammunition sensitivity is a factor. Some types of ammunition may have harder primers, requiring a more forceful strike from the firing pin.
Troubleshooting trigger and firing pin problems often begins with a thorough inspection and cleaning of the trigger assembly. Disassembling and reassembling the trigger assembly can reveal any worn or damaged components. Inspection and replacement of trigger components can be helpful. A dirty or poorly lubricated trigger will not work smoothly. Checking the firing pin protrusion is essential to make sure the firing pin is striking the primer with sufficient force. Replacing worn firing pin springs can often resolve light primer strike issues.
Accuracy Considerations
While the Kel Tec Sub 2000 Gen 3 is not designed as a precision rifle, the shooter certainly expects a certain degree of accuracy. However, it is important to acknowledge its limitations.
Inherent Accuracy Limitations
The Sub 2000’s design, while practical, does present some inherent accuracy limitations. The barrel length and the open sights contribute to some of these limitations. The sights themselves may not be ideal for precision shooting. The design is more geared towards rapid target acquisition at shorter distances. This does not mean that it cannot be accurate, but it is important to acknowledge that its strengths lie elsewhere.
Sight Problems
The factory sights of the Sub 2000 are rudimentary, especially the front sight post. While functional, these sights can be challenging for some shooters, especially those accustomed to more sophisticated sight systems. Poor visibility, especially in low-light conditions, may make it difficult to achieve accurate shots. Aftermarket sights are available, but some can have issues. With red dots and other optics, ensuring a proper co-witness with the iron sights requires some degree of adjustment.
Troubleshooting sight problems can involve several steps. The shooter can replace the factory sights with aftermarket options. Red dot sights are also popular, and the process of co-witnessing with iron sights can increase confidence in any situation. These upgrades can improve the shooter’s ability to aim and hit targets accurately.
Durability and Build Quality
The Sub 2000’s construction, particularly its use of a polymer frame, raises questions about its long-term durability.
Plastic Construction and its Weaknesses
The polymer frame offers advantages in terms of weight and cost, but it’s important to acknowledge its potential weaknesses. Frequent use and rough handling can lead to wear and tear on the polymer, increasing the risk of cracks or breaks. The folding mechanism, a key feature of the Sub 2000, is a high-stress area that can loosen over time. The stress and the use of this part can create wear that could render the part unusable.
Addressing durability concerns requires careful handling and proactive maintenance. Inspecting the frame regularly for cracks or signs of wear is critical. Avoid dropping or banging the firearm. Consider the use of protective cases during transport. Furthermore, certain aftermarket modifications can reinforce potential weak points in the frame and the folding mechanism.
Parts Failure
Over time, certain parts in the Sub 2000 may be subject to wear and potential failure. This can include the recoil spring, firing pin spring, and other small components. Regular inspection and timely replacement of worn parts can prevent malfunctions.
Troubleshooting involves regular inspection, identifying worn parts, and timely replacement. Replacement parts are easily available.
Other Considerations
Besides the issues noted above, there are a few other potential concerns that Sub 2000 owners should be aware of.
Folding Mechanism Issues
The folding mechanism, a defining feature, can sometimes present its own set of problems. The mechanism can be prone to binding if debris gets lodged in it, and improper operation can lead to wear and tear. Lubrication is key, and proper cleaning and adjustment of the folding mechanism will ensure that it functions smoothly.
Magazine Compatibility
Magazine compatibility issues can also arise. The Sub 2000 is designed to accept specific magazines. The shooter should test with a variety of magazines and note the issues, such as the lips or other parts of the magazines.
