The RPK is a light machine gun that appears in Call of Duty: Black Ops.

The RPK was first seen in the reveal trailer for the game. In-game screenshots appear to show that the weapon uses a forty round magazine and a bipod. It was then seen twice in the Wager Match trailer, once with an Infrared Scope and again with a Red Dot Sight, and with high amounts of recoil.
