SureFire KM4 LED WeaponLight Conversion Kit for M96/M900/M500 Series, Includes New Head, Tailcap, O-Rings, O-Ring Lubricant, Applicator Brush, Black

The SureFire KM4 LED WeaponLight Conversion Kit (Black) is a direct screw-on replacement for the existing head on certain SureFire Millennium Universal WeaponLights, Dedicated Forend WeaponLights and Vertical Foregrip WeaponLights, produces both brilliant white light and intense IR output from one dual-LED emitter assembly. A bezel selector ring allows you to easily switch back and forth from white to infrared output and it is self-locking so it stays securely on the selected light output, until you decide otherwise.

The high-efficiency LEDs are virtually immune to failure since there's no filament to burn out or break and provide significantly longer runtimes per set of batteries than incandescent emitters of similar output. It features a Total Internal Reflection (TIR) lens that produces a comparatively tight beam suited for close- to medium-range applications. The O-ring sealed aerospace aluminum body is Mil-Spec hard anodized.
