Ok, so I would like to mount my little cannon HD point and shoot to the SIDE rail of my gun. this was i could also use the same mount on my M4 when i do CQB. i could make it mount with scope rings, but i need a housing thats bb proof. even if all i can do is turn it on, put it in the case and hit record, i would prefer to see the screen but it needs to be covered to. I mainly need a technique, types of materials, and something for the lens.... i have no idea how to cover that.
