Stalcraft Wiki: RK-2

"The RK-2 is a heavy-duty foregrip designed for maximum recoil control. It offers substantial reductions to vertical and horizontal recoil while providing the highest recoil buildup reduction available. These benefits come at a significant cost to aim speed and draw speed, making it best suited for players who prefer sustained, accurate fire over quick-reaction handling. It is a cornerstone for high-RPM assault rifles that otherwise become difficult to control during long bursts."
