Whether you're a seasoned shooter or just starting out, the SUB-2000 is a fantastic piece of engineering. It's known for its portability, its compatibility with various pistol magazines, and its overall reliability. In this comprehensive guide, we'll cover everything from the rifle's design and features to common issues, troubleshooting tips, and even some cool customization options. Let's get started!

Unveiling the Kel-Tec SUB-2000: Design and Features

First things first, what exactly makes the Kel-Tec SUB-2000 so special? Well, the SUB-2000 is a semi-automatic, pistol-caliber carbine (PCC) designed and manufactured by Kel-Tec. One of its most distinctive features is its ability to fold in half, making it incredibly compact and easy to store or transport. This folding design is a major selling point for those who value discreet carry or limited storage space. The SUB-2000 is chambered in either 9mm Luger or .40 S&W, allowing it to use magazines from a variety of popular handguns, such as Glock, Smith & Wesson, and Beretta, depending on the model you choose. This magazine compatibility is a huge advantage, as it allows you to share magazines with your existing handguns, reducing the number of different magazines you need to carry and simplifying your ammo logistics. The SUB-2000 typically features a blowback operation system, which is a simple and reliable mechanism, making the rifle easier to maintain and less prone to malfunctions compared to more complex systems. The barrel length on the SUB-2000 is usually around 16 inches, which provides a significant boost in muzzle velocity and accuracy compared to handguns using the same ammunition. The rifle also includes iron sights, usually consisting of an adjustable rear sight and a fixed front sight, allowing for quick target acquisition. However, many owners choose to upgrade to aftermarket optics for enhanced accuracy. The SUB-2000's design prioritizes lightweight materials, making it easy to handle and carry for extended periods. The receiver is typically made of aluminum or a polymer composite, reducing the overall weight. The stock is often made of polymer, further contributing to the rifle's portability. The controls are generally simple and user-friendly, with an ambidextrous safety and a magazine release button. Disassembly for cleaning and maintenance is straightforward, which is another plus for those who prefer to keep their firearms in top condition. Overall, the Kel-Tec SUB-2000 is a versatile and practical firearm that balances portability, magazine compatibility, and ease of use, making it a favorite among gun owners.

Common Kel-Tec SUB-2000 Problems and Solutions

Alright, guys, even though the SUB-2000 is a pretty reliable firearm, it's not immune to issues. Let's get into some of the most common problems you might encounter and how to fix them. A lot of the issues with the SUB-2000 can be resolved with a little troubleshooting and some basic maintenance. This is where your knowledge comes in handy and will save you money on gunsmithing. Understanding these issues will make you a more informed and confident shooter. One of the most common complaints is failure to feed (FTF). This occurs when the round doesn't properly chamber into the barrel. This can be caused by a few different things. Firstly, the magazine could be the culprit. Make sure your magazine is clean and in good working condition. Check the feed lips for any damage or wear. Also, ensure you are using quality ammunition. Some cheap or inconsistent ammo can cause feeding issues. Another common cause of FTF is a dirty chamber. Carbon buildup can prevent the round from seating properly. Cleaning the chamber thoroughly with a brush and solvent is often the solution. If the problem persists, the extractor could be at fault. The extractor is responsible for pulling the spent casing out of the chamber and allowing a new round to be loaded. Check to make sure the extractor is in good shape and that the spring hasn’t weakened. Next up, we have failure to eject (FTE). This is when the spent casing doesn't get extracted from the chamber. This can also be caused by a dirty chamber. As the casing expands during firing, it can get stuck if the chamber isn't clean. The extractor could also be worn or damaged and unable to properly remove the casing. If your extractor is worn, consider replacing it. A weak ejector spring could also be an issue. If the ejector isn’t pushing the casing out with enough force, you'll have an FTE. The SUB-2000 can also experience stovepiping, where the spent casing gets stuck partially out of the ejection port, resembling a stovepipe. This is usually related to extraction and ejection issues. Check the extractor, ejector, and chamber cleanliness. Another common problem is jamming. Jams can occur due to a variety of factors, including dirty magazines, incorrect ammunition, and worn or damaged parts. Regularly cleaning and lubricating the firearm and using high-quality ammunition can help prevent jams. Lastly, trigger issues are occasionally reported. These can include a heavy trigger pull or a trigger that doesn't reset properly. If you experience trigger problems, you should first clean and lubricate the trigger mechanism. If the problem persists, it may be necessary to replace the trigger spring or even the entire trigger assembly. Proper maintenance and regular cleaning are key to preventing many of these problems. Always follow the manufacturer's instructions for cleaning and maintenance. Regular inspection of your SUB-2000 will help you catch problems early and keep your rifle running smoothly. If you're not comfortable performing the repair yourself, don't hesitate to take your rifle to a qualified gunsmith.

Troubleshooting Tips:

• Failure to Feed (FTF): Check magazine, ammo, chamber cleanliness, and extractor.
• Failure to Eject (FTE): Clean the chamber, inspect and replace extractor and ejector.
• Stovepiping: Check extractor, ejector, and chamber cleanliness.
• Jams: Clean magazines, use correct ammo, inspect parts.
• Trigger Issues: Clean and lubricate, replace trigger spring or assembly.

Kel-Tec SUB-2000 Maintenance and Cleaning

Alright, let's talk about keeping your SUB-2000 in tip-top shape. Regular cleaning and maintenance are super important for ensuring your rifle functions reliably and has a long life. It's not rocket science, but it does require some attention to detail. Let's break down the cleaning process step by step, so you can keep your SUB-2000 running like a champ. Before you start, always make sure your rifle is unloaded. Remove the magazine and visually inspect the chamber to ensure there are no rounds present. Safety first, always! Gather your cleaning supplies. You'll need a cleaning rod, bore brush (for 9mm or .40 S&W, depending on your model), cleaning patches, gun cleaning solvent, gun oil or lubricant, and a brush for cleaning the small parts. Disassembly: The SUB-2000 is relatively easy to disassemble. Consult your owner's manual for specific instructions for your model. Typically, you'll remove the front handguard, then the barrel assembly from the receiver. Cleaning the Barrel: Attach the bore brush to your cleaning rod. Dip the brush in the cleaning solvent and run it through the barrel from the chamber end to the muzzle end. Repeat this several times. Then, switch to cleaning patches and run them through the barrel until they come out clean. Pay extra attention to the chamber, as this area is prone to carbon buildup. Cleaning the Bolt and Receiver: Use a brush and solvent to clean the bolt and the inside of the receiver. Pay attention to any areas where carbon or debris has accumulated. Lubrication: Once everything is clean and dry, it's time to lubricate the moving parts. Apply a thin coat of gun oil or lubricant to the bolt, the rails in the receiver, and any other areas where metal parts rub together. Be careful not to over-lubricate, as excess oil can attract dirt and grime. Reassembly: Reassemble your SUB-2000 according to the manufacturer's instructions. Once reassembled, function-check the rifle to ensure everything is working correctly. This means manually cycling the bolt and checking the trigger. Regular maintenance will make a world of difference. Proper maintenance not only keeps your rifle running smoothly but also helps prevent malfunctions and extends its lifespan. By following these steps, you can keep your SUB-2000 performing at its best for years to come.

Cleaning Supplies:

• Cleaning rod

Whether you're looking to improve accuracy, ergonomics, or just want to make your SUB-2000 stand out, there are plenty of options. Let's explore some popular customization choices to make your rifle truly your own! One of the most common upgrades is adding optics. The SUB-2000 features a Picatinny rail, allowing you to easily mount red dot sights, scopes, or other optics. A red dot sight can significantly speed up target acquisition, making it ideal for fast-paced shooting. Scopes offer increased magnification for longer-range shooting. Before you buy an optic, consider your intended use and the range you typically shoot at. Another popular customization is a handguard. Some aftermarket handguards replace the original handguard with one that offers additional features, such as M-LOK slots for attaching accessories like lights, lasers, or foregrips. The handguard is a great way to improve your rifle's ergonomics and modularity. Speaking of ergonomics, you can also upgrade the stock and grip. There are various aftermarket stocks that offer adjustable lengths of pull, better cheek welds, or a more comfortable feel. Upgrading the grip can improve your control and comfort when shooting. Replacing the trigger is another option. Upgrading the trigger can significantly improve the feel and performance of the trigger, resulting in a cleaner break and a lighter pull weight. This can lead to increased accuracy and faster follow-up shots. You can also customize the appearance of your SUB-2000. There are various aftermarket parts available that can change the look of your rifle, such as different colored handguards, stocks, and other components. You can even have the receiver cerakoted to give your rifle a unique finish. Always remember to make sure your upgrades comply with all applicable laws and regulations.
