"Combination handled grips allow for highly maneuverable assaults. For operators who care less about where their shot lands and more about getting rounds down range fast."
— Description

XRK ChainSAW is an attachment featured in Call of Duty: Modern Warfare. It replaces the standard stock of the gun with two grips, one on top of the gun and one which replaces the trigger action and stock in a matter which appears similar to the grip placements on a chainsaw. The top grip blocks the iron sights of the gun, so a hip fire crosshair will be shown when aiming. 

The attachment is exclusive to the FiNN LMG.
