I was concerned about the particular review entitled "not bad, but not great either" since they describe their experience with a Mossberg 500 putting pressure on the barrel.
I'd recommend against it myself. i have yet to completely understand the "need" a lot of people have to put multiple rails on everything. At short range you won't have the need for a laser and it will probably be washed out by the flashlight or not easily visible during daylight. Plus there is the question of, how are you going to activate the light? is the switch going to be velcroed to the fore-end with a coiled cord, so the fore-end can be moved? One thing I seriously recommend against is installing the 3 rail replacement fore-end. I know they would have a tendency to draw blood if rail isn't cover when the shot gun is fired.
I think you would be much happier with a light that is built in to the fore-end I know Surefire makes them and they can be pricey, but I see Insight makes one for them too. Perhaps you might have luck finding a used one. Good luck in however you choose to go.
You just have to ask yourself, is he telling you the truth based on knowledge and experience or spreading internet myths?

At 10 yards, my gun shoots a bit high compared to where the existing bead sight is. This is strictly a home defense gun so I was looking to get a laser so I could calibrate it to the distance I'd be shooting. I want something that is strictly point and shoot. A green laser would be bright enough to work during the day or with a flashlight. I'll work out the mechanics on how to activate the light once I get everything in. Probably will be manually or using a pressure pad on the fore-end.
To avoid the whole "you don't need that for HD" type arguments, I was simply looking for suggestions on a product that would do what I want. I guess I don't NEED a tri rail setup, but those are most commonly what I've seen to hook onto magazine tubes. If you know of a single rail system that hooks on a magazine tube I'd be interested in hearing about that too.
