How to Choose the Best Laser Sight for Kel-Tec SUB2000

When selecting a laser sight for your Kel-Tec SUB2000, there are several factors to consider:

1. Laser Type: Red vs. Green

  • Green lasers are generally more visible in daylight and offer better visibility at longer distances. However, they tend to be more expensive and can drain batteries faster than red lasers.
  • Red lasers, on the other hand, are more affordable and offer sufficient visibility in low-light conditions. They are also more energy-efficient, providing longer battery life.

2. Light Output

  • If you plan to use your SUB2000 in low-light or nighttime environments, a laser/light combo is ideal. Look for a laser sight with a light output that suits your needs. High-lumen lights are great for illumination, but they can also be blinding in close quarters, so consider your typical use scenario.

3. Size and Weight

  • The Kel-Tec SUB2000 is known for its lightweight and compact design, so it’s important to choose a laser sight that complements these features. A bulky or heavy laser could upset the balance of the firearm, making it less comfortable to handle.

4. Ease of Use

  • Features like instant activation or ambidextrous controls can make a significant difference, especially in high-stress situations. Ensure that the laser sight you choose is easy to operate and can be quickly engaged when needed.

5. Durability

  • Your laser sight needs to withstand the rigors of regular use, including recoil, environmental conditions, and rough handling. Look for products that are built with high-quality materials and have a reputation for durability.

6. Battery Life

  • Consider the battery life of the laser sight, especially if you plan to use it frequently. Some sights offer rechargeable batteries, which can be more convenient and cost-effective over time.

FAQs

1. Can I use a green laser during the day?

  • Yes, green lasers are more visible in daylight compared to red lasers. They offer better visibility over longer distances, making them ideal for outdoor shooting.

2. How do I attach a laser sight to my Kel-Tec SUB2000?

  • Most laser sights are designed to be mounted on the Picatinny or Weaver rail system. Simply slide the laser sight onto the rail and tighten it securely using the provided tools or by hand.

3. Do I need to re-zero my laser after each use?

  • In general, you should check the zero on your laser sight regularly, especially after extensive use or if the firearm has been dropped. High-quality laser sights typically hold their zero well, but it’s good practice to verify accuracy periodically.

4. What is the typical battery life of a laser sight?

  • Battery life can vary widely depending on the type of laser and whether the sight includes a light. Green lasers tend to use more power than red lasers, and adding a light can further reduce battery life. On average, you can expect between 1.5 to 2 hours of continuous use.

5. Are there laser sights with rechargeable batteries?

  • Yes, some laser sights, such as the OLIGHT Baldr Pro R, come with rechargeable batteries. These can be a convenient option, eliminating the need to constantly replace batteries.

Conclusion

Choosing the right laser sight for your Kel-Tec SUB2000 can significantly enhance your shooting experience, providing improved accuracy, faster target acquisition, and added versatility. Whether you prioritize a bright green laser, a laser/light combo, or a compact design, the products listed above are some of the best options on the market today. By considering your specific needs and preferences, you can find the perfect laser sight to complement your SUB2000 and take your shooting to the next level.
