Surefire Xt00 Tailcap Swtch X Series

The SureFire XT00 tailcap switch brings remote activation capability to your SureFire X-Series weapon light, giving you control and flexibility at the point of aim. If you run a tactical rifle, shotgun, or pistol with a Picatinny rail and an X-Series light, the XT00 lets you operate your light from a pressure pad rather than fumbling with controls at the tail cap—a real advantage in training, competition, or duty work where your hands are managing the gun.

The XT00 replaces your X-Series light's standard tail cap with a robust remote-ready design. You get a constant-on/off toggle switch for reliable activation and a separate lockout toggle that guards against accidental discharge of the light during storage, transit, or active use. The titanium latch holds strong in rough conditions, and the switch pairs with SureFire's ST07 and SR07 cable assemblies (including the SR07-D-IT and their extended-length variants) to route control wherever you need it. Whether you're setting up a home-defense carbine, a patrol rifle, or a night-training setup, the XT00 turns your X-Series light into a true tactical tool.

This is a straightforward, field-proven accessory that solves a real problem: hard-to-reach tail-cap buttons under stress. The remote switch interface is intuitive—toggle for on/off, toggle for safety—so there's no learning curve, and it integrates seamlessly into whatever rail platform and cable run you already have in mind.
