The Surefire M340C Scout Weapon Light in black (M340C-BK-PRO) from Surefire is an ultra-compact firearm light with the power to make it easy to see in the dark. A low-profile mount is used to secure the light to your weapon, freeing up your hands and enabling you to keep focused on the task at hand, while ensuring that your light never gets in the way. Rugged and reliable, this light’s recoil-proof LED produces a staggering 500 lumens from a single 123A battery for up to an hour.

This light has been carefully designed to allow flexibility in its use. Compatible with both MIL-STD-1913 (Picatinny) and M-LOK rails, you can mount this light just about anywhere on your weapon without compromising your ability to handle it or carry the other accessories you use. A Mil-Spec Hard-Anodized aerospace aluminum body will keep your light in good condition for years to come, even in the rough conditions you experience in the field. This light is suitable for medium and long-range applications.
