SureFire delivers the ultimate long gun light with the M640DFT. It utilizes SureFire’s exclusive Dual Fuel technology, allowing it to be powered with either a single SF18650B rechargable lithium-ion battery (included), or with two 123A batteries (not included). When using the SF18650B battery, the M640DFT produces a blinding 100,000 candela beam at distances up to 632 meters. When equipped with two 123A batteries, the M640DFT features a 90,000 candela beam at distances of 600 meters. Regardless of the batteries used, the M640DFT is ideal for long-range target identification. The M640DFT attaches to the host weapon via SureFire’s Scout Light Pro Low-Profile Mount (LPM), allowing the user to optimize the light’s position relative to the rail and other rail-mounted accessories. The LPM is increadably rugged and is compatible with any MIL-STD-1913 rail as well as M-LOK interfaces. In addition, the M640DFT is activated with a ZE68 momentary/constant-on push-button switch, but is compatible with a wide range of remote tape switches as well.
