The X400GN Ultra LED Flashlight and Green Laser Sight from SureFire combines a 500-lumen, single-output, LED light with a 505nm Class IIIb green aiming laser for Picatinny or universal rail mounts. The light features SureFire's Total Internal Reflection (TIR) lens that produces a pre-focused beam with a tight center cone of bright light, and a dimmer ring on the periphery to help maintain situational awareness. An ambidextrous toggle switch controls the momentary and constant-on modes. The selector switch, located behind the laser, switches the output modes and features a lock-out function to prohibit accidental activation during storage or when strict light discipline must be maintained. The green laser is easy to see and can be readily differentiated from other aiming lasers used by devices like Tasers. Designed for durability, this system features a weatherproof o-ring and gasket sealed Mil-Spec anodized aluminum housing.

    Comments about SureFire X400GN Ultra LED Flashlight and Green Laser Sight:

    I put this on my Ruger SR-556 and couldn't be happier. I have the first version X400 laser/light combo on my Glock and wanted a bit more lumues for the rifle. Well I got what I wanted, an amazing bright light comparable to the sun. The green laser shows up clearer then anything I've seen before. Shining the light on a white wall is blinding but the laser still stands out and easily seen. I'm very impressed with the new upgraded version of this light. With the first version is same with this version, you still have to remove the light to change the batteries, its the only downside to the complete system.
