The Kel-Tec Sub 2000 is a unique and popular pistol-caliber carbine (PCC) known for its compact, foldable design and affordability. However, many owners find opportunities to enhance its already impressive capabilities through modifications. This article will explore various Kel-Tec Sub 2000 mods, ranging from simple upgrades to more substantial changes, focusing on improving accuracy, ergonomics, and overall functionality. We'll also delve into the importance of choosing the right modifications based on your intended use.
Understanding Your Needs Before Modification
Before diving into specific modifications, it's crucial to define your goals. What aspects of the Sub 2000 do you want to improve? Are you primarily focused on accuracy, ergonomics, aesthetics, or a combination of these factors? Your goals will dictate the types of modifications that will offer the best return on investment.
For example, if accuracy is your top priority, you might prioritize upgrades like a better trigger, enhanced sights, or a different barrel. If ergonomics are more important, modifications like an improved brace or grip might be your focus. Considering these factors from the outset will prevent unnecessary expenses and ensure you invest wisely.
Popular Kel-Tec Sub 2000 Modifications
The Sub 2000's modularity allows for a wide range of modifications. Let's explore some of the most common and effective upgrades:
Enhanced Sights and Optics
The factory sights on the Sub 2000 are functional, but many shooters prefer upgraded options. Here are some popular choices:
-
Red Dot Sights (RDS): An RDS dramatically improves target acquisition and accuracy, especially at close to medium ranges. Many owners opt for low-profile RDS mounts to maintain the Sub 2000's compact profile. Popular choices often include Aimpoint, Holosun, and Sig Sauer optics.
-
Night Sights: For low-light shooting conditions, night sights provide a significant advantage. These sights incorporate tritium or other luminous materials for enhanced visibility.
-
Magpul MBUS Sights: These are a cost-effective alternative to higher-end sights, offering a significant improvement over the factory iron sights. They are rugged and reliable, suitable for various shooting conditions.
Table 1: Comparison of Sight Options
| Sight Type | Cost | Acquisition Speed | Durability | Low-Light Performance |
|---|---|---|---|---|
| Factory Iron Sights | Low | Moderate | Good | Poor |
| Magpul MBUS | Moderate | Good | Excellent | Moderate |
| Red Dot Sight | High | Excellent | Good to Excellent | Varies (depends on model) |
| Night Sights | Moderate to High | Good | Good | Excellent |
Trigger Upgrades
The Sub 2000's trigger is often cited as an area for improvement. A smoother, lighter trigger pull can significantly improve accuracy and overall shooting experience. However, trigger modifications require caution and potentially professional gunsmithing to maintain safety and reliability. Some options include:
-
Aftermarket Trigger Kits: Several companies offer aftermarket trigger kits designed to improve the Sub 2000's trigger feel. These kits usually involve replacing some internal components, requiring some mechanical aptitude or the services of a qualified gunsmith. Always prioritize safety and follow all manufacturer instructions.
-
Trigger Job: A professional gunsmith can perform a trigger job, carefully adjusting and smoothing the trigger mechanism for a more refined pull. This option requires expertise and should only be done by someone experienced with firearms modifications.
Brace Upgrades
The Sub 2000's brace is a point of contention for some. While it provides stability, some users find it uncomfortable or insufficient. Upgrades include:
-
Aftermarket Braces: Numerous aftermarket braces are available offering improved ergonomics and comfort. These braces often provide adjustments for length and angle, allowing for a customized fit. Always ensure the brace complies with all applicable laws and regulations.
-
Custom Braces: Experienced gunsmiths can also create custom braces tailored to the individual shooter's preferences and needs. This is a more expensive option but can result in a significantly improved shooting experience.
Other Modifications
Other common Kel-Tec Sub 2000 modifications include:
-
Enhanced Grips: Replacing the factory grip with an ergonomic aftermarket grip can significantly improve comfort and control during shooting.
-
Extended Magazines: Increasing magazine capacity extends the Sub 2000's operational time between reloads.
Case Study: Enhancing Accuracy with a New Barrel and Red Dot Sight
One Sub 2000 owner, John, experienced inconsistent accuracy with the factory barrel and sights. He upgraded to a heavier, more precisely manufactured barrel and a high-quality red dot sight. The results were dramatic. His groups tightened considerably, improving his accuracy by roughly 40% at 25 yards. This highlights how strategic modifications can dramatically improve performance.
Conclusion: Tailoring Your Kel-Tec Sub 2000
Modifying your Kel-Tec Sub 2000 can significantly enhance its capabilities and personalize it to your needs. Remember to prioritize safety and research each modification thoroughly before proceeding. Start with smaller, less invasive modifications, and gradually add more substantial upgrades as needed. By carefully selecting and installing the right modifications, you can transform your Sub 2000 into a highly effective and personalized firearm. Always consult with a qualified gunsmith for complex modifications and ensure all work complies with applicable laws and regulations.
