SureFire M640DFT Scoutlight Pro Turbo LED Weapon Light with 2 CR123A Batteries - Aluminum$377.00
Availability: In Stock
The Surefire M640U Scoutlight Pro LED weapon light is a 1000-lumen tactical light purpose-built for rifle and carbine platforms where versatility, durability, and real-world performance matter. Whether you're training on the range, running low-light drills, or gearing up for field work, this compact aluminum light delivers the output and beam characteristics serious shooters depend on.
Built around a high-output LED and a proprietary TIR lens, the M640U shapes its beam to strike the balance between reach and peripheral illumination—useful whether you're working indoors at close quarters or scanning terrain at medium distance. The light runs for approximately 1.25 hours on the two included CR123A batteries, giving you substantial runtime for typical training and deployment scenarios. The aerospace-grade aluminum body is hard-anodized to mil-spec standards and sealed with O-rings, so it can handle the recoil impulse of centerfire rifles and the weather it collects along the way without degrading.
The standout feature here is Surefire's Low-Profile Mount (LPM), which lets you dial in exactly where the light sits on your rail system. Instead of forcing your light into a fixed position that may conflict with other mounted gear, the LPM gives you the freedom to optimize placement relative to your scope, sight, or other accessories. The mount works on any MIL-STD-1913 Picatinny or M-LOK equipped forend or handguard. Activation is intuitive: a protected push-button tailcap switch for intuitive cycling between momentary and constant-on modes. That simplicity under stress is what separates tools from gadgets.
If you run a modern rifle platform and want a compact, proven light that doesn't sacrifice output or user control, the M640U earns its place in your kit.
