However, like any firearm that sees regular use, the Sub 2000 might eventually require some maintenance, and one of the most common procedures is Kel Tec Sub 2000 barrel replacement. This guide aims to provide a comprehensive and easy-to-understand resource for safely and effectively replacing the barrel on your Sub 2000, ensuring you can keep your carbine functioning at its best.
Safety Precautions
Prior to embarking on any firearm modification, and especially Kel Tec Sub 2000 barrel replacement, the utmost priority must be placed on safety. This is not a task to be taken lightly. The handling of firearms always carries risks, and any procedure on a firearm requires absolute attention to detail and respect for the inherent dangers. This guide is for informational purposes only; if you are not comfortable with the process or have any doubts, consult a qualified gunsmith.
Always, always, always verify that your firearm is completely unloaded. This means removing the magazine, racking the charging handle to eject any round in the chamber, and visually inspecting the chamber to ensure it is clear. Continue to keep the muzzle pointed in a safe direction, away from yourself and others, at all times during the Kel Tec Sub 2000 barrel replacement procedure.
Wearing appropriate eye and ear protection is absolutely essential. Safety glasses will protect your eyes from any debris that may become airborne during disassembly or reassembly. Ear protection, such as earmuffs or earplugs, is vital to shield your hearing from the loud noise associated with working on firearms, especially when using tools like hammers.
Choose a well-lit and clean workspace. A cluttered workspace can lead to confusion and potential accidents. Having an organized area with all the necessary tools and parts readily available will make the process far easier and safer. Consider using a sturdy workbench or table to provide a stable surface for working.
Finally, familiarise yourself with all local and federal laws. Ensure that you are compliant with all applicable regulations regarding firearms ownership, modifications, and barrel replacements.
Tools and Materials Needed
The Kel Tec Sub 2000 barrel replacement process necessitates a specific set of tools and materials. Gathering the right equipment upfront will significantly streamline the task and minimize frustration.
You will need a selection of screwdrivers, including those with different sizes, with possibly Torx drivers. These will be needed to remove the various screws used on the firearm.
A set of punches is also crucial. These are used to drive out pins that secure various parts of the Sub 2000. Make sure to have a range of sizes available.
A hammer is required, ideally, a rubber mallet to avoid damaging any components.
A vice and vice blocks are incredibly helpful, and although optional, will help to stabilize the receiver during the barrel removal and installation processes, reducing the risk of damage.
If applicable, a torque wrench is another helpful tool. This will be used to ensure that the barrel nut is tightened to the correct specifications. This will ensure safety and consistent performance of your Kel Tec Sub 2000.
To maintain the smooth operation of your firearm, cleaning supplies are a must. You will need a cleaning solvent and lubricating oil. A well-maintained firearm functions more efficiently.
Protective gloves can help to keep your hands clean and to improve your grip.
You’ll require a new Sub 2000 barrel. Ensure that the new barrel is the correct model for your specific Sub 2000 variant and caliber. Double-check the barrel length to ensure it matches your requirements and local regulations.
Depending on the design of the barrel, you may need a barrel nut.
Threadlocker, such as Loctite, will be needed to secure screws and other components.
Lastly, depending on how involved you want to be with the Kel Tec Sub 2000 barrel replacement, you may also need to replace your handguard.
Preparation Before Disassembly
Before initiating the Kel Tec Sub 2000 barrel replacement procedure, proper preparation is essential. This will allow for a smooth and efficient process.
The first step is field stripping your Sub 2000. This means disassembling the firearm to its basic components for maintenance. Familiarize yourself with the field stripping instructions, which can be found in the owner’s manual or online through various tutorials. This is not the complete takedown, you only need to separate the upper and lower receiver. Remove the magazine and ensure the chamber is clear.
Carefully examine your current barrel. Look for any signs of damage, excessive wear, or corrosion. If you’re experiencing issues with accuracy or if you notice any bulges or deformities, it is likely time for a Kel Tec Sub 2000 barrel replacement.
Photographic documentation of the firearm will be a big help. Take photos and notes of the existing configuration of the rifle before disassembly. This is a valuable reference when it comes time for reassembly, helping you remember the correct placement of parts and screws.
Barrel Removal
The actual process of removing the old barrel is a critical part of the Kel Tec Sub 2000 barrel replacement procedure. This must be done with extreme care and attention to detail.
If your Sub 2000 has a handguard/forend, the initial step involves its removal. Follow the handguard removal instructions for your particular model. This usually involves removing screws or pins holding it in place.
Depending on your Sub 2000 model, you may have a barrel nut that needs to be removed or loosened. Follow the relevant procedures for your specific configuration.
Once the handguard or barrel nut is removed, you can start the process of separating the barrel from the receiver. This may involve tapping the barrel out from the front of the receiver. Use a punch and a rubber mallet to gently tap the barrel out. If the barrel seems stuck, apply penetrating oil and allow it to soak for some time.
In the process of removing the barrel, pay close attention to the orientation of any components. Note the location of any alignment marks or indexing features. These features ensure proper alignment during reassembly, such as the front sight. Make sure to retain these small parts, such as shims, and note their placement. Failing to maintain alignment can severely impact the performance of your Sub 2000.
Barrel Installation
Once the old barrel is removed, it’s time for the new barrel to be put in. The following are the steps in the Kel Tec Sub 2000 barrel replacement.
Before the new barrel is installed, make sure to clean it, and remove any factory grease or packing materials. This will allow for a more precise fit and promote optimal performance.
Place the new barrel in the receiver. Ensure it is properly aligned. You might need to align the barrel with any existing indexing features or marks.
Install the barrel nut (if your model uses one) and tighten it to the manufacturer’s specified torque. Use a torque wrench to ensure that you tighten it correctly. Over-tightening or under-tightening the barrel nut can affect accuracy and can create safety issues.
Then re-assemble your other parts according to the original notes and images taken before disassembly. Reinstall the handguard, and make sure that all screws are tightened securely.
Post-Installation Checks and Testing
Following the installation of the new barrel, the final steps of the Kel Tec Sub 2000 barrel replacement are critical.
Thoroughly examine the firearm to make sure everything is properly aligned. Ensure there are no gaps or misalignments. Inspect all components, including the sights, to make certain they are properly secured.
Perform a function check, a series of tests designed to ensure that the firearm functions correctly. This involves verifying the bolt cycles smoothly, the trigger functions as expected, and the safety mechanisms are working correctly. Load a dummy round (or snap cap) into the magazine and cycle the action. Make sure it loads, fires, and extracts.
Once you’ve verified the function, it is now time for testing, if safe and legal to do so. Head to a shooting range where you can safely test fire your Sub 2000. Start with the proper range safety protocol, and start with a few rounds to verify the barrel replacement. Remember to monitor your groups and note any changes in accuracy or point of impact.
Troubleshooting
Despite the best efforts, some issues can occur during the Kel Tec Sub 2000 barrel replacement process. If your bolt won’t cycle correctly, make sure the barrel is correctly aligned, and the barrel nut is properly tightened. If the trigger isn’t working, recheck the installation of the trigger components. If the issue persists, consult with a qualified gunsmith.
Maintenance and Care
To ensure that your firearm stays in optimal condition after the Kel Tec Sub 2000 barrel replacement, regular maintenance and care are essential.
Proper cleaning of the barrel is essential to maintain accuracy and extend its lifespan. Use appropriate cleaning solvents, bore brushes, and cleaning rods to remove any powder residue, fouling, and other contaminants. Be sure to follow the manufacturer’s instructions for cleaning and lubrication.
Regular lubrication of the internal moving parts of the firearm will help it function properly. This includes lubricating the bolt carrier group, the trigger mechanism, and other areas recommended by the manufacturer. Use high-quality gun lubricants to ensure smooth operation.
Perform regular inspections of your firearm, looking for any signs of wear, damage, or corrosion. Check all screws, pins, and other components to ensure they are secure. If you identify any issues, have them addressed promptly.
Upgrading the Sub 2000 (Optional)
During the Kel Tec Sub 2000 barrel replacement project, you may consider other modifications and upgrades. The Sub 2000 is popular for the range of available aftermarket accessories, including handguards, trigger upgrades, sights and optics, and various other enhancements.
Consider upgrading your handguard to a more modern design with M-LOK or Picatinny rail sections to allow for mounting of accessories. A better handguard will increase comfort and functionality.
Another modification is upgrading the trigger, which will improve the overall performance of the firearm.
The addition of sights and optics will also help with accuracy.
