In collaboration with Treyarch Studios, the Grav Slam Performance Thumbsticks were created to satisfy the unique ergonomic and performance requirements of Call of Duty: Black Ops 4 players, while also paying homage to the powerful character Ruin. It has two thumbsticks: a mid-rise (7.0 mm) for added comfort and grip, and a high-rise (11.2 mm) for better shooting accuracy. This produces a tactical combination that lets you maximize controller sensitivity for faster, more accurate movements in-game and increases range of motion by 120%. Show off your accuracy by using the included code to redeem a Target Practice Calling Card at www.callofduty.com/redeem as an extra bonus.
