While it is a bit of a departure for us, when the Mossberg 590 Shockwave came out we quietly waited for the aftermarket to allow addition of a simple light/laser combo to the factory forearm. We just wanted a laser and a white light mounted to the forearm where we could get at it from any point in the pump cycle to cut through the fog on a night match stage gun. What emerged from the aftermarket were bulky, multi-purpose rail skeletons that went against the nature of such a compact gun. So, we decided to make it happen ourselves: Nestled among our other unique sighting options, the Sight Saddle - Light Rail Platform (SS-LRP) is a simple way to mount a Light/Laser to any Mossberg factory polymer 'Corn Cob' forearm. http://www.or3gun.com/OR3GUN/about_or3gun_sightsaddle.htm As the Shockwave was designed to pack a punch into a lightweight package, we went with the same philosophy. The SS-LRP mounts between your Shockwave's forearm and the factory strap using the longer, included screws. The SS-LRP includes a lightweight, polymer Magpul MOE 5-Position Rail section at no additional cost. Your hand doesn't have to leave the safety of the forearm strap to have full control over your light/laser. Still very much a Mossberg 930 focused company, but we like to play with the latest toys too!
