Surefire M340C Mini Scoutlight Pro LED Weapon Light - Includes 1 CR123A Battery, Aluminum Construction

The Surefire M340C Mini Scoutlight Pro is a compact LED weapon light built for shooters who refuse to compromise between firepower and weight. Mounted to your rifle, carbine, or shotgun rail, this tactical light delivers 500 lumens of TIR-focused output from a single CR123A lithium battery—enough to run at full intensity for a full hour of operations. The ultra-high-output LED is virtually indestructible, and the focused beam blends enough flood light for close-quarters work with enough reach for longer-distance target acquisition.

Built from aerospace-grade aluminum with a Mil-Spec hard anodized finish, the M340C is sealed with O-rings and rated IPX7 to shrug off rain, dust, and the wear that comes with serious use. The new Low-Profile Mount (LPM) lets you position the light exactly where you need it relative to your rail system—critical if you're running other accessories like optics or backup iron sights. It clamps securely to either MIL-STD-1913 (Picatinny) or M-LOK rails without tools.

Activation is straightforward: a protected push-button tailcap switch gives you momentary or constant-on control. If your rifle setup calls for a pressure pad instead, Surefire supplies an activation tape switch on appropriate models. At this size and weight, the Mini Scout Light Pro adds capability without bogging down your rifle, making it equally at home on a tactical AR, a hunting rifle, or a home-defense shotgun.
