The Surefire UE-BK Rear Cap integrates with compatible Surefire Scout Light Weapon Lights and specified Surefire flashlights, converting their interface from a standard push-button to accept a Surefire remote tape switch. This modification facilitates pressure-activated light control, a critical requirement for weapon-mounted illumination where momentary or constant-on function is needed without compromising weapon grip. It represents a precise upgrade for optimizing light management.
Key Features
Construction & Durability
The UE-BK is constructed from aerospace-grade aluminum, selected for its superior strength-to-weight ratio and resilience. The component undergoes MilSpec Type III hard-anodizing, providing a durable, corrosion-resistant finish that mitigates wear from environmental exposure and sustained operational use.
Control & Discipline
An integrated positive lock-out mechanism prevents unintended light activation. This design feature is critical for maintaining light discipline, conserving battery life during storage or transport, and ensuring controlled illumination deployment in high-stakes operational scenarios.
Compatibility & Application
This rear cap is engineered for direct compatibility with Surefire M300 and M600 Scout Light Weapon Lights. Furthermore, it integrates seamlessly with other Surefire flashlights featuring a .75-inch diameter switch, encompassing models such as the E1E-HA, E1B, E1L-HA-WH, E2D-BK, E2DL-BK, E2L-HA-WH, and L4-HA-WH. Its utility extends across a broad spectrum of applications, from enhancing personal defense firearms to enabling precise illumination control on a precision rifle system. When integrated with appropriate tactical optics, this rear cap facilitates effective low-light engagement, ensuring setup remains versatile and responsive, whether for duty use or within typical shooting range equipment configurations.
