The Sig Sauer Foxtrot-MSR is a rifle-mounted white light purpose-built for modern carbines and short-barreled platforms that demand serious output without bulk. This compact tactical light delivers 1350 lumens and 33,000 candela of illumination from a durable 6061 aluminum body, giving you the brightness needed to identify targets and threats downrange while maintaining a profile that doesn't bloat your rail real estate. If you're running a short-barrel rifle for home defense, patrol, or dynamic shooting, the Foxtrot-MSR brings professional-grade light to the fight.
Activation is intuitive: an integrated push button gives you both momentary and latching modes, so you can keep the light on or pulse it as your situation demands. The included remote tape switch with SureFire-compatible connector lets you run the light from your foregrip or wherever feels natural on your platform—no fumbling for controls during the moment. Runtime stretches to 1.5 hours on a single 18650 lithium-ion battery, with two included so you've got a spare without needing to hunt for power.
Mounting flexibility is built in: the Foxtrot-MSR ships with both Picatinny rail and M-LOK interfaces, making it compatible with virtually any modern rifle platform. Scout Mount compatibility opens even more options for placement and configuration. The anodized aluminum finish is tough enough for hard use while keeping weight down where it matters.
