The M640DF-PRO Scout Pro combines the best attributes of the standard M640 Scout Pro with high-candela performance and dual-fuel capability.
SureFire long-gun WeaponLight. Ideal for long-range target identification, the M640DF-PRO projects a blinding, peak beam intensity of 1500 candela when powered by the included SF18650B rechargeable lithium-ion battery, or when powered by two 123 lithium batteries. Its precision reflector creates a tightly focused, concentrated shaft of light with minimal bounce when peering over, under or around barricades. Our 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 M640DF is the best-performing, most durable, and most feature-rich WeaponLight for its size.
