SureFire M140ABKPRO Micro Scout Light Pro Tactical Rifle Light - 300 Lumens, 65m Beam, Picatinny/M-LOK Mount, Black Anodized Aluminum

The SureFire M140ABKPRO Micro Scout Light Pro is a compact tactical rifle light built for shooters who need reliable low-light target identification without adding bulk to their platform. At just 2.08 ounces with batteries installed, this 300-lumen weapon light delivers serious illumination in a footprint so minimal it barely impacts your rifle's profile or handling. Whether you're clearing rooms, navigating low-light terrain, or confirming what's downrange before you take a shot, the Micro Scout Light Pro gives you the light you need, when you need it.

SureFire engineered this light from the ground up around their proven Scout Light platform, but stripped it down to essentials. A recoil-proof premium LED and smooth parabolic reflector focus the beam to 1,045 candela of peak intensity, punching out to 65 meters effectively. You get a full 1.25 hours of runtime from a single rechargeable AAA battery (included), so you're not burning through disposables on every trip to the range or field. The shrouded push-button tailcap lets you toggle between momentary-on for tactical use or click through to constant-on when you need sustained illumination.

Built tough for the real world: the light is machined from aerospace-grade aluminum and hard-anodized to MIL-A-8625 Type III, Class 2 specs. That means it shrugs off scratches, corrosion, and the wear that comes with hard use. O-ring sealing keeps moisture and dust out in harsh conditions. The included Low-Profile Mount ships with both Picatinny (MIL-STD-1913) and M-LOK attachment options, so you can mount it tight to the rail on virtually any modern rifle platform without fumbling with different components. Mounting flexibility means you place the light exactly where it works best for your setup and shooting style.
