Stalcraft Wiki: Empuñadura angular RK-1

"Focusing on vertical recoil reduction, the RK-1 is the vertical counterpart to the REG Fab Defense grip. It matches the horizontal grip's sway reduction and stabilization but applies its primary benefit to vertical climb. This makes it an excellent choice for battle rifles or high-caliber weapons with predictable but strong upward kick. Like the REG, it carries a draw speed penalty, necessitating a methodical approach to engagement."
