The M511A Dedicated Forend WeaponLight replaces the original handguards of your M16 / AR-15 or similar rifle. It features a 9-volt shock-isolated incandescent lamp, dual low-output navigation lights, and three separate primary beam switches integrated into the forend: constant-on rocker switch (left side), a momentary-on pressure pad switch (right side), and a system disable rotary switch (rear of battery housing) to lock the light in the OFF position for covert operations or to eliminate accidental light activation during storage. The navigation lights, available in white, red, or blue, are activated by a smaller momentary-on pressure pad on the left side of the forend. Proven in combat, used by military and law-enforcement around the world. - Fits: M16 / AR-15-style weapons with triangular handguard caps
