I added this to my Mossberg 590 Flex. Everyone who has seen it has dropped their jaws looking at it. It just looks intimidating. This shotgun, however, is NOT my primary home defense firearm. Due to the weight of the rail (and all of the accessories that most people will add), I would not recommend this being added to a primary home defense shotgun. It is just way too heavy with all the weight for tactical purposes. It does make my Mossy a great conversation piece!
Pros: Ability to mount anything
Cons: Weight
