Shockwave light and laser. - Nightstick Shotgun Forend LED Light For Mossberg 500/590/Shockwave with Laser

The Nightstick was easy to attach, and the laser was dead on out of the box The lED is bright and useful even in daylight. The laser is visible in daylight at short distances and great at night. The only drawback is the weight. It weighs almost as much as the as the entire weapon, but I would still recommend one.
