The SureFire M140ATNPRO Micro Scout Pro is a compact tactical rifle light engineered for shooters and operators who need reliable low-light target identification without weighing down their platform. At just 300 lumens with a 65-meter beam, this mounted light delivers focused illumination across the distances that matter in close-quarters and tactical scenarios. The tan anodized aluminum body is built tough—aerospace-grade construction with mil-spec hard anodizing—and sealed against the elements so it holds up in the field whether you're doing positive ID work, navigating low-light terrain, or running sensitive operations where every ounce and inch count.
The Micro Scout Pro runs on a single rechargeable AAA battery and pulls 1.25 hours of continuous runtime, keeping your rifle nimble and your logistics simple. The included low-profile mount ships with both Picatinny and M-LOK options, so it adapts to your rail setup without fuss. The push-button tailcap is straightforward: press for momentary activation, click through for constant-on. It's fast, intuitive, and works the way a duty light should. SureFire's parabolic reflector focuses the beam cleanly, and the shrouded design protects the switch from snags and accidental activation.
This is the kind of gear that earns its place on a rifle because it stays out of the way until you need it. Lightweight, compact, IPX7-rated for water resistance, and backed by engineering that's proven in demanding environments—the Micro Scout Pro is built for the shooter who refuses to compromise between capability and profile.
