SureFire Z-XBC Switch Assembly for X300/X400/XH30 Lights Tan

The SureFire Z-XBC Switch Assembly transforms weapon light activation with instant-on capability for X300, X400, and XH30 series lights. This tail cap replacement provides tactical operators with reliable momentary and constant-on switching in a combat-proven polymer construction.

What Makes This Different

Unlike standard push-button tail caps, the Z-XBC features a larger activation surface that reduces fumbling under stress. The switch assembly integrates seamlessly with existing SureFire weapon lights while maintaining the same waterproof rating as original components. Polymer construction resists impact damage that can crack aluminum switches during weapon manipulation.

Key Features

• Direct replacement for factory tail caps on X300/X400/XH30 series lights
• Flat Dark Earth polymer construction matches tactical weapon finishes
• Momentary-on activation with twist for constant operation
• O-ring sealed design maintains IPX7 waterproof rating
• Oversized activation pad for reliable operation with gloves
• Drop-in installation requires no modifications or tools
• Textured surface prevents slippage during weapon handling

Field testing demonstrates consistent activation across temperature ranges from -40°F to 140°F. The polymer material flexes under impact rather than cracking, maintaining switch integrity during weapon drops or rough handling. Law enforcement and military units report improved activation speed compared to standard button switches, particularly when operating with heavy gloves or in low-light conditions.
