Originally designed for Special Forces, this round was created to achieve ballistics of similar calibers, yet fit into a standard M4 using normal bolts and magazines with the usual capacities. It can also operate at subsonic speeds, making it quieter. Accuracy is good up to 150 yards and recommended to hunt feral hogs and deer.
