The Kel-Tec Sub 2000 is a popular pistol-caliber carbine known for its compact design and ease of disassembly. However, like any firearm, its barrel might eventually require replacement due to wear and tear, damage, or the desire to upgrade to a different caliber or barrel profile. This guide provides a comprehensive overview of the process, considerations, and resources for replacing a Kel-Tec Sub 2000 barrel.
Why Replace Your Kel-Tec Sub 2000 Barrel?
Several factors might necessitate a barrel replacement for your Sub 2000:
- Wear and Tear: After extensive use, the barrel can show signs of wear, including erosion of the rifling, leading to decreased accuracy and potentially affecting the firearm's reliability.
- Damage: Accidental damage, such as dropping the firearm or impacting the barrel against a hard surface, can cause bending, dents, or other damage requiring replacement.
- Upgrades: Many shooters choose to upgrade their Sub 2000 with a different barrel to improve accuracy, alter the ballistic profile, or switch calibers (where applicable). For example, a heavier barrel can reduce recoil and improve precision.
- Customization: Some aftermarket barrels offer enhanced features like threaded muzzles for suppressors or different finishes for aesthetics and corrosion resistance.
Choosing the Right Replacement Barrel
Selecting the appropriate replacement barrel is crucial. Consider these factors:
- Caliber: Ensure the replacement barrel matches the caliber of your Sub 2000 receiver. Incorrect caliber matching is extremely dangerous and should be avoided at all costs.
- Barrel Length: Different barrel lengths affect the velocity and accuracy of your ammunition. Longer barrels generally provide higher velocities, while shorter barrels offer greater maneuverability.
- Material: Barrels are typically made from steel or stainless steel. Stainless steel offers greater corrosion resistance but might be slightly heavier.
- Profile: The barrel's profile (contour) can influence handling and accuracy. Heavy barrels offer better stability, while lighter barrels are easier to maneuver.
- Manufacturer: Choose a reputable manufacturer known for producing high-quality, reliable firearms components.
The Barrel Replacement Process
Disclaimer: Replacing a barrel on a firearm requires mechanical aptitude and familiarity with firearms. If you are not comfortable performing this task, seek the assistance of a qualified gunsmith. Improper installation can lead to malfunctions, damage to the firearm, and potential injury.
While the exact steps may vary slightly depending on the manufacturer and model of the replacement barrel, the general process typically involves:
- Disassembly: Carefully disassemble your Sub 2000 according to the manufacturer's instructions. This typically involves removing the upper receiver, bolt, and other components.
- Barrel Removal: Remove the existing barrel from the receiver. This may involve removing retaining pins or other fasteners.
- Barrel Installation: Carefully install the new barrel into the receiver, ensuring proper alignment.
- Reassembly: Reassemble the Sub 2000, following the manufacturer's instructions precisely.
- Function Check: Before firing, thoroughly inspect the firearm to ensure all components are correctly installed and functioning properly. Then, perform a function check to verify the firearm operates safely.
