A replica of the Surefire M900AB Tactical flashlight is now available at RSOV.com.  We are not sure if this ACM is an exact replica of  M900AB which has the following description: "Vertical Foregrip WeaponLight attaches to Picatinny rail interface-equipped weapons via a built-in A.R.M.S. throw-lever mount. Each unit is equipped with five separate switches:

(1) two pressure-sensitive momentary activation pads to control the main battle light -- one on each side of the grip for ambidextrous operation (2) a constant-on switch (3) a system disable switch to lock the light in the­ OFF position for covert operations or to eliminate accidental light activation during storage, and (4) a third, smaller momentary switch to control two low-output LEDs that are useful whenever there is a need for a very small amount of light (stealth navigation, nighttime breaching operations, etc.) "
