SureFire X400V-B-IRC MasterFire WeaponLight with Infrared Laser: Unrivaled Tactical Illumination and Aiming Solutions

In high-stakes environments where every second and every detail counts, the ability to rapidly identify threats, acquire targets, and maintain situational awareness can be the difference between success and failure. For professionals in law enforcement, military operations, and serious tactical enthusiasts, the challenges of low-light engagements demand equipment that is not just reliable, but truly transformative. Imagine a scenario where you need to transition seamlessly from visible light to covert infrared illumination for night vision devices, all while maintaining absolute control and precision over your firearm. This is precisely the critical problem the SureFire X400V-B-IRC WeaponLight with Infrared Laser is engineered to solve, offering an unparalleled blend of versatility, robust performance, and seamless integration with advanced tactical systems.

The SureFire X400V-B-IRC is more than just a weapon light; it's a comprehensive tactical tool designed to elevate your operational capabilities in any lighting condition. It stands as the cornerstone of SureFire's innovative MasterFire holster system, providing the essential interface for quick deployment and secure retention for a wide array of pistols equipped with tactical rails. But its utility extends far beyond handguns, proving equally effective on long guns such as carbines and shotguns, making it a truly universal solution for demanding applications.

Engineered for Critical Missions: Why the SureFire X400V-B-IRC Stands Apart

What makes the SureFire X400V-B-IRC an indispensable asset for those who operate in the shadows or under immense pressure? Its design is rooted in the practical needs of operators who demand instant-on light activation and a multifaceted approach to target illumination and acquisition.

Seamless MasterFire Holster System Integration

One of the most defining features of the X400V-B-IRC is its specialized compatibility with the SureFire MasterFire Rapid Deploy Holster system. This isn't just about carrying your weapon; it's about the lightning-fast, secure, and intuitive deployment of your firearm with integrated illumination. The weapon light’s cam-slotted bezel and unique rear locking lugs on the battery housing are meticulously engineered to interface flawlessly with the MasterFire holster. This design ensures absolute secure weapon retention, preventing accidental dislodgement even during dynamic movements or high-stress situations, while simultaneously facilitating an incredibly fast and natural draw stroke. For anyone who prioritizes weapon security without compromising on speed, this integration is a game-changer. It means your light and laser are always precisely where they need to be, ready to activate the moment your weapon clears the holster, minimizing response time in critical moments.

Dual-Spectrum Illumination: White Light and Infrared for Unmatched Versatility

The "V-Series" head of the SureFire X400V-B-IRC is its brain, providing a sophisticated two-in-one illumination solution. This single compact unit delivers both dazzling visible white light and covert infrared (IR) illumination, a crucial feature for operators working across varied environments and operational profiles.

• Tactical-Level White Light (350 Lumens): When overt illumination is required, the X400V-B-IRC blasts a powerful 350 lumens of bright, tactical-level white light. This intense beam is optimized for close-to-medium range engagements, providing ample illumination to identify threats, navigate dark environments, and disorient potential adversaries. Its focused beam effectively penetrates darkness, offering a clear visual advantage in critical situations, reaching out to an impressive 225 meters to illuminate targets downrange.
• Covert Infrared (IR) Illumination (120 mW): For clandestine operations or use in conjunction with Night Vision Goggles (NVGs), the ability to switch to infrared illumination is paramount. The X400V-B-IRC delivers 120 milliwatts (mW) of IR light, invisible to the naked eye but perfectly suited for illuminating targets when viewed through NVGs. This allows operators to maintain their tactical advantage under the cover of darkness, performing reconnaissance, surveillance, and target engagement without giving away their position with visible light. The seamless transition between white light and IR illumination is achieved with a simple, intuitive toggle switch, ensuring operational flexibility on the fly.

Integrated Infrared Laser Aiming Device

Complementing its dual-spectrum illumination, the SureFire X400V-B-IRC features an integral Class 1 infrared laser aiming device. This IR laser provides a precise, sub-visible aiming point that is only detectable with NVGs, making it an invaluable tool for enhanced accuracy in low-light and no-light conditions.

• Precision Aiming in Darkness: When operating with night vision, a visible laser would compromise concealment. The IR laser of the X400V-B-IRC allows for rapid target acquisition and precise aiming, even when traditional iron sights or red dot optics are difficult to use under NVG conditions. This translates to significantly improved hit probability and faster target engagement, especially when dealing with moving targets or engaging from unconventional shooting positions.
• Tactical Advantage: The ability to project an invisible aiming point is a profound tactical advantage. It allows operators to maintain a low profile, conduct covert engagements, and operate effectively without betraying their position. For specialized units, this feature is not merely a convenience but a fundamental requirement for mission success.

Robust Construction and Versatile Mounting

SureFire is synonymous with durability, and the X400V-B-IRC is no exception. Constructed from aerospace-grade aluminum with a hard-anodized finish in black, this weapon light is built to withstand the harshest operational environments.

• Uncompromising Durability: The black anodized aluminum body ensures exceptional resistance to corrosion, abrasion, and impact. This rugged construction means the X400V-B-IRC can endure the recoil of high-caliber firearms, extreme temperatures, and the rigors of combat or demanding training, guaranteeing consistent performance when it matters most. Its water-resistant properties further enhance its reliability in adverse weather conditions.
• Universal Mounting Solutions: The SureFire X400V-B-IRC features a quick-detach rail clamp system that provides fast, secure attachment to both Universal and Picatinny MIL-STD-1913 rails. This universal compatibility means it can be effortlessly mounted on a wide range of handguns and long guns that feature a tactical rail. The quick-detach mechanism allows for rapid installation and removal without tools, offering unparalleled flexibility for operators who need to quickly reconfigure their equipment.

User Experience and Practical Applications

Understanding how a tool performs in the hands of an operator is key to assessing its true value. The X400V-B-IRC is designed for intuitive operation and maximum efficiency.

Intuitive User Interface

The ambidextrous push/toggle switch allows for easy activation and mode selection, catering to both left- and right-handed shooters. This ergonomic design ensures that the light and laser can be activated instantly, even under stress, without breaking your grip or compromising your shooting stance. The simple toggle allows for quick transitions between visible light, IR illumination, and laser-only modes, adapting instantly to changing tactical requirements.

Extended Runtime and Power

Powered by readily available CR123A batteries, the X400V-B-IRC offers impressive runtimes of up to 16+ hours, ensuring sustained performance during extended operations. This long battery life minimizes the need for frequent battery changes, allowing operators to focus on their mission rather than power management.
