The Kel-Tec Sub 2000 is a popular pistol-caliber carbine known for its unique folding design and affordability. However, like any firearm, its accuracy and usability depend heavily on the quality of its sights. This guide delves into the Kel-Tec Sub 2000 rear sight, covering its features, potential upgrades, and troubleshooting common issues.
Understanding the Factory Rear Sight
The factory-installed rear sight on the Kel-Tec Sub 2000 is a relatively simple, fixed-blade design. It's functional for basic shooting, offering a fairly broad notch for target acquisition. Its simplicity, however, also presents some limitations for those seeking enhanced accuracy or adaptability to various shooting conditions. The primary drawbacks often cited include:
- Limited adjustability: The factory sight offers no windage or elevation adjustments. This means that any zeroing must be done through adjustments to the front sight, which can be more cumbersome.
- Basic design: The simple blade design doesn't offer features like ghost ring or aperture sights, which can provide faster target acquisition in certain scenarios.
- Durability concerns: While generally robust, some users report issues with the sight's finish or potential for damage under heavy recoil.
Upgrading Your Kel-Tec Sub 2000 Rear Sight
Many Kel-Tec Sub 2000 owners opt to upgrade their rear sight for improved performance and personalization. Several aftermarket options exist, catering to different preferences and shooting styles:
Aftermarket Sight Options: A Quick Overview
Several manufacturers offer replacement rear sights specifically designed for the Kel-Tec Sub 2000. These typically offer advantages over the factory sight, such as:
- Adjustable sights: These allow for precise windage and elevation adjustments, crucial for optimal zeroing at various distances. This eliminates the need for front sight adjustments, streamlining the process.
- Improved sight picture: Some aftermarket sights utilize ghost ring or aperture designs for faster target acquisition, particularly beneficial in low-light conditions or during rapid engagement.
- Enhanced materials and construction: Many aftermarket sights are constructed from durable materials like aluminum or steel, offering improved resilience against wear and tear.
Troubleshooting Common Rear Sight Issues
While generally reliable, the Kel-Tec Sub 2000 rear sight can sometimes present problems. Here are a few common issues and potential solutions:
- Sight alignment problems: If your shots are consistently off, ensure the rear sight is properly aligned with the front sight. You might need to adjust the front sight (if it's adjustable) or consider a sight upgrade offering adjustability.
- Sight damage: Inspect the rear sight for any signs of damage or wear, such as bending or scratches. Replacement might be necessary if the damage affects sight alignment or functionality.
- Loose sight: A loose rear sight can significantly affect accuracy. Check if the sight is properly secured and tighten it if necessary (consult your owner's manual for instructions).
Conclusion
The Kel-Tec Sub 2000 rear sight, while functional in its standard form, can be a limiting factor for those seeking enhanced accuracy and adaptability. Upgrading to an aftermarket sight is a popular modification among Kel-Tec Sub 2000 owners, offering significant improvements in sight picture, adjustability, and durability. Understanding the limitations of the factory sight and exploring available aftermarket options allows for personalized customization to optimize shooting performance. Remember always to prioritize safety and consult with qualified professionals when modifying firearms.
