This is by far the most interesting product announcement of the day: a Picatinny quad-rail attachment for double barrel side-by-side shotguns. Laserlyte, the company that is making it, says it is designed specifically for coach type shotguns made by Stoeger and Cimarron and that it is ideal for mounting lasers, pistol bayonets and other accessories.
Since it weighs nearly half a pound, it can also help alter the swing characteristics of your shotgun should you desire an extreme weight-forward balance.
Given the chance, here's what I'd put on my Model 21: a red-dot sight on top, a laser with a pressure pad on/off switch on one side, a bayonet on the other and a pistol grip with an integral weapon light on the bottom rail.
The boys at the sporting clays club would faint from envy.
