Activation Mechanism
- Choose between touch-activated, button-activated, or automatic activation based on your preference and tactical needs.

Not all laser sights are compatible with the Kel-Tec KSG. It’s essential to choose one that can be securely mounted and withstand the shotgun’s recoil.
2. What is the difference between red and green lasers?
Green lasers are more visible in daylight, while red lasers are generally sufficient for low-light conditions and are more affordable.

Regularly check the alignment, clean the lens, and ensure the battery is charged or replaced as needed. Follow the manufacturer’s maintenance guidelines to ensure optimal performance.
