Upgrade your handgun or long gun light control with the SureFire Z-XBC Switch Assembly in Tan. Purpose-built for popular SureFire X-Series weaponlights—including X300, X400, and XH30—this drop-in tailcap/switch unit delivers reliable momentary and constant-on activation, improved ergonomics, and rugged duty-ready construction. Whether you’re setting up a concealed-carry pistol, a duty rig, or a carbine with an X-Series light, the ZXBCTN gives you SureFire’s renowned switching performance in a lightweight, impact-resistant polymer body that won’t quit when conditions turn ugly.

Key Benefits at a Glance

• Perfect Fit for X-Series Lights: Designed specifically for SureFire X300 / X400 / XH30 weaponlights for seamless compatibility and secure lock-up.

• Dual-Mode Activation: Momentary press for quick, positive-ID bursts; constant-on with a deliberate click for extended illumination and two-hand tasks.

• Duty-Grade Durability: Impact-resistant tan polymer and sealed construction help resist recoil, weather, and hard knocks.

• Enhanced Ergonomics: Low-profile paddles provide tactile control from a variety of shooting grips—barehanded or gloved.

• Color-Matched Aesthetics: Tan (FDE-style) finish blends with coyote/tan holsters, frames, and gear for a clean, professional look.

Why Choose the Z-XBC for Your X-Series Setup

• Trusted SureFire Switching: Crisp detents and reliable contact geometry minimize accidental activations while ensuring repeatable, positive engagement under stress.

• Optimized for Handgun & Carbine Use: Works equally well on pistols in holsters and on rifle/PDW mounts where thumb activation is preferred.

• No-Nonsense Install: Drop-in replacement that keeps your existing X-Series bezel and body—no need to buy a new light.

• Lightweight, Strong, Ready: Keeps total weapon weight down without compromising the bomb-proof SureFire reputation for reliability.

Ideal Use Cases

• Concealed Carry & Duty Pistols: Fast, intuitive activation for positive target identification and room searches.

• Home Defense Carbines: Simple, glove-friendly paddles that work from barricades and unconventional positions.

• Training & Competition: Repeatable switch feel builds consistent low-light manipulations and reduces fumbles on the clock.

Installation (Quick Guide)

1. Verify Safe: Ensure firearm is unloaded; remove the light from the weapon.

2. Remove Old Tailcap: Unscrew the existing X-Series tailcap/switch.

3. Install Z-XBC: Thread the Z-XBC switch assembly onto the light body until snug.

4. Function Check: Test momentary (press/hold) and constant-on (press/click) before remounting the light on your firearm.

Tip: Add a small witness mark on the tailcap and body to visually confirm tailcap tightness during inspections.

Care & Maintenance

• Keep Contacts Clean: Wipe contacts and threads with a dry cloth; avoid over-lubrication.

• Inspect Periodically: Confirm tight tailcap, intact paddles, and consistent activation after high-round-count sessions.

• Environmental Check: Rinse with fresh water after salt/dust exposure; dry thoroughly.

Compatibility

• SureFire Weaponlights: X300, X400, XH30 (select models and variants).
