About SureFire M312C

When it comes to tactical lighting solutions, the M312C 3V Scout Light with DS07 Switch Assembly and RM45 Offset Mount stands out with its compact design and high-output LED that emits a powerful 300 lumens of blinding white light. This lightweight, yet robust, WeaponLight is engineered with a proprietary TIR lens that shapes the recoil-proof LED's light into a focused beam, offering extensive reach while also providing sufficient surrounding light to support peripheral vision. This makes the M312C 3V Scout Light an ideal choice for a wide range of applications, from close-quarter to longer-range operations.

The M312C 3V Scout Light is designed for quick and secure attachment to any MIL-STD-1913 rail, thanks to its integral low-profile RM45 mount. This unique mount positions the light in an off-set position between the rails of a MIL-STD-1913 (Picatinny) forend, effectively reducing the overall weapon profile and minimizing the potential snag factor.

Activation of the light is made simple and reliable with a waterproof DS07 switch assembly. This assembly includes a click-on/off pushbutton switch, a system-disable feature, and an ST07 plug-in momentary-on remote switch with a seven-inch cable. The integrated pushbutton and remote switch assemblies operate independently, ensuring switch redundancy for added reliability.

Constructed from lightweight aerospace aluminum, the M312C 3V Scout Light is hard anodized with a Mil-Spec finish for enhanced durability. It's also O-ring sealed to resist the elements, making it a reliable companion in combat-like conditions. This tough yet lightweight WeaponLight provides a tactical advantage in low-light situations, without compromising weapon maneuverability.

  • RM45 mount positions the light in the off-set position between the rails of a MIL-STD-1913 (Picatinny) forend, decreasing overall weapon profile and limiting potential snag factor
