It would certainly at least need a light, a laser, a red dot, a small backup holographics sight, 2 bayonets (one on rifle and one on the shotgun), a sidesaddle on the shotgun, a heat shield on the shotgun, two death-dealing compensators (again, one for the rifle and one for the shotgun) a few spare magazines (at least one on the stock of the ar and two clamped to the magazine in the well), a scope extender, an NVG, and about six vertical foregrips placed in various spots (you may need to rotate the gun at different angles but you'll still need the verticals to look cool). Oh yeah, you'll need some batteries containers attached to some of the rails or all that crap won't work.
