• Control Your Light with Integrated & Remote Switches: The system includes a remote tape switch with a SureFire-compatible plug, allowing you to activate the light momentarily without shifting your grip. You can also use the integrated tail cap button for both momentary and latching (constant-on) modes, giving you versatile control options for any engagement.
• Mounts Securely to M-LOK & Picatinny Rails: This light ships with both M-LOK and Picatinny rail mounts, so it fits your rifle immediately without requiring extra adapters.
