SureFire's Scout Light Pro series rewrote the rules of WeaponLight versatility. The M340DFT combines high-candela performance and dual-fuel capability. The M340DFT delivers the farthest-reaching beam of any SureFire long gun WeaponLight in a compact form factor. As a result, it is ideal for long-range target identification. The M340DFT projects a peak beam intensity of 71,000 candela, using the included SF18350 rechargeable lithium-ion battery, or 33,000 candela with a single 123A primary battery. It offers tremendous versatility by also providing ample spill light for situational awareness without sacrificing long-range performance. The Scout Light Pro Low-Profile Mount (LPM) delivers unprecedented versatility, allowing the user to optimize the light's position relative to the rail and other attached firearm accessories. Rugged and reliable, the LPM easily and securely attaches to any MIL-STD-1913 or M-LOK rail. Constructed of lightweight aerospace aluminum, Mil-Spec hard-anodized, and O-ring sealed to keep out the elements, the M340DFT Scout Light Pro is the best-performing, most feature-rich, WeaponLight for its size.
