Why Kel-Tec Sub 2000 Aftermarket is Necessary
From my experience, the Kel-Tec Sub 2000 is an excellent platform, but the aftermarket upgrades truly elevate its performance and usability. I found that the stock parts, while functional, often lack the customization and durability I want for different shooting scenarios. Aftermarket components allow me to tailor the rifle to my specific needs, whether that’s improving accuracy, enhancing ergonomics, or increasing reliability.
Another reason I consider aftermarket parts necessary is that they help address some of the Sub 2000’s common quirks. For example, upgrading the sights or adding a better trigger significantly improves my shooting confidence and speed. Additionally, accessories like extended magazines, enhanced charging handles, or reinforced buffers make the rifle more comfortable and consistent during extended use. In short, the aftermarket ensures my Kel-Tec Sub 2000 performs exactly how I want it to, making it a much more versatile and enjoyable firearm.
My Buying Guides on Kel-Tec Sub 2000 Aftermarket
When I first decided to customize my Kel-Tec Sub 2000, I quickly realized how important it was to choose the right aftermarket parts. The Sub 2000 is a versatile and compact firearm, but with the right upgrades, it can become even more efficient and tailored to my shooting style. Here’s what I learned and what I recommend considering when shopping for aftermarket accessories.
Understanding the Kel-Tec Sub 2000 Platform
Before diving into aftermarket options, I made sure to fully understand the unique design and function of the Sub 2000. It’s a folding carbine that’s lightweight and uses popular handgun magazines, which means some parts are specific to this model. Knowing the platform helped me identify compatible accessories and avoid parts that wouldn’t fit or perform well.
Key Aftermarket Parts to Consider
When upgrading my Sub 2000, I focused on a few essential categories:
- Optics and Sights: The factory iron sights are decent, but I wanted quicker target acquisition. I looked for red dot sights and mounting solutions compatible with the Sub 2000’s top rail. Brands offering low-profile mounts or integrated optics were a big plus.
- Extended Magazines and Mag Releases: Since the Sub 2000 accepts magazines from popular pistols (like Glock or Smith & Wesson), I found extended magazines that increased capacity and improved reload speed. Upgraded magazine releases also made magazine swaps smoother.
- Charging Handles: The factory charging handle on the Sub 2000 can be a bit stiff for some shooters. I found aftermarket charging handles with ergonomic designs that made racking the slide easier and more comfortable.
- Handguards and Rails: Adding additional rail space allowed me to attach lights, lasers, or grips. I chose lightweight handguards that didn’t add much bulk but increased functionality.
- Sling Mounts: For better carry options, I installed aftermarket sling mounts compatible with tactical slings. This made my Sub 2000 easier to carry during longer sessions.
Material and Build Quality
One thing I paid close attention to was the build quality of aftermarket parts. The Sub 2000 is known for its lightweight aluminum and polymer construction, so I wanted parts that wouldn’t add unnecessary weight but still offered durability. I often chose components made from aircraft-grade aluminum or reinforced polymer for the best balance.
Compatibility and Fitment
Not all aftermarket parts are created equal, especially when it comes to the Sub 2000. I always double-checked compatibility with my specific model and magazine type. Reading user reviews and forums helped me avoid parts that caused fitment issues or required excessive modification.
Ease of Installation
I’m not a gunsmith, so I looked for parts that were easy to install with basic tools. Many aftermarket upgrades for the Sub 2000 are designed for drop-in installation, which saved me time and frustration. If a part required professional fitting, I considered whether the performance benefit justified the effort.
Price vs. Performance
Aftermarket parts can vary widely in price. For me, it was important to balance cost with quality and performance gains. I avoided extremely cheap parts that might fail or cause damage, and I didn’t overspend on upgrades with marginal benefits. Setting a budget helped me prioritize the most impactful modifications.
Where to Buy
I found reliable aftermarket parts from specialty firearm accessory shops, both online and local. Websites dedicated to Kel-Tec accessories often had the best selection. I also checked out user feedback on forums and YouTube reviews before making a purchase.
Final Thoughts
Customizing my Kel-Tec Sub 2000 with aftermarket parts transformed my shooting experience. By focusing on compatibility, quality, and practical upgrades, I was able to enhance reliability, ergonomics, and functionality without compromising the platform’s unique advantages. If you’re considering aftermarket upgrades, take your time researching and choose parts that truly fit your needs and shooting style.
