Surefire KM4 LED Conversion Kit w/ White & IR Output
The V-Series KM4 LED conversion head, 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. The KM4 head 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 in your choice of Black (BK) or Desert Sand (TN). Kit includes: conversion head, new head and tailcap O-rings, O-ring lubricant, and applicator brush.

Fits: M5(xx) Dedicated Forend WeaponLights, M9(xx) Vertical Foregrip WeaponLights, M96(xx) Millennium Universal WeaponLights
