When in the inventory, it seems to affect item pickups in a way that favors the Rivet Gun, in that the odds of collecting an abundance of rivet ammo as opposed to ammo for other weapons seems to be high which may be intended to compensate for the Rivet Gun's high ammo consumption and low damage. It has a default of 16 rivets per magazine and a maximum of 24. The rivets are also relatively inexpensive at the store. The primary fire shoots almost as fast as you can pull the trigger and the secondary fire detonates up to five of the rivets currently fired out of your gun and makes them bounce off the walls of the room you are in.

As revealed in the Gamestop trailer for the Rivet Gun, it is a rapid fire weapon that can pin Necromorphs to walls. The 711-MarkCL Rivet Gun appears in Dead Space 2 as a pre-order exclusive from Gamestop and was later included in the Supernova Pack.
