Instructions need updating. - Nightstick Shotgun Forend LED Light For Mossberg 500/590/Shockwave with Laser

OK. I got a Mossburg 590 Shockwave for close self defense. I was looking for an aiming assist but knew that sights were not applicable. You do not want to hold one of these short 12 GA shotguns up to your face. The Nightstick looked great. A new fore end incorporating an LED flashlight and laser. Big downside, the instructions are inadequate. Big upside, the device is well designed and well manufactured. Even with the inadequate instructions, I was able to get it installed and operating in about an hour. Controls are very well placed. It is very easy to replace the batteries although the instructions do not tell you that there is a two battery holder in the battery space. When you initially open the battery space, it looks as if only a single battery fits but it is actually a cartridge that needs to be removed to install both batteries. Have not yet shot any rounds through it, but it racks well and feels solid.
