SureFire M340DFT-TN-PRO: The Ultimate Dual Fuel Scout Light with Picatinny Rail/M-LOK Swivel MountThe SureFire M340DFT is a powerful long gun light designed for optimal performance and versatility. It features SureFire's exclusive Dual Fuel technology, which means it can be powered by either a single SF18650B rechargeable lithium-ion battery (included) or two 123A batteries (not included).When using the SF18650B battery, the M340DFT produces an incredibly bright beam with 95,000 candela, allowing for long-range target identification up to 616 meters. If you prefer to use two 123A batteries instead, the light still offers a substantial output of 55,000 candela and can illuminate targets at distances of up to 469 meters. The M340DFT is specifically designed for attachment to a host weapon using SureFire's Scout Light Pro Low-Profile Mount (LPM). This mount enables the user to optimize the light's position relative to the rail and other rail-mounted accessories. The LPM is highly durable and compatible with any MIL-STD-1913 rail, as well as M-LOK interfaces. To activate the M340DFT, it features a ZE68 momentary/constant-on push-button switch. However, it is also compatible with various remote tape switches, providing flexibility in how you control the light. The SureFire M340DFT offers a powerful and adaptable lighting solution for long guns, delivering exceptional performance and the ability to use different power sources depending on your needs.
