Nice product - SureFire Remington 870 12 Gauge Shotgun 6V LED Forend WeaponLight

Product is top notch. Paid the extra dollars and got the one with the switch. Probably not a necessity. Light is extremely bright and service from Optics Planet was exceptional. Note it does not come with the internal parts so you will need to swap out your tube assembly and nut or buy another set. IF you swap parts, it is best accomplished with a forend wrench.
Pros: Extremely bright light
Cons: Makes weapon somewhat front heavy
