18 LBS - 80 FPS. The Man Kung MK-RB015 recurve bow is a little bit more powerful than the MK-RB009. This is because the limbs are slightly longer. The string has the same length, so the limbs are tensioned a bit more. That makes it shoot harder. The riser of this bow is fitted with bright green elements which look nice with the black limbs. This MK-RB015 bow is suitable for both right-handed and left-handed archers and comes with the necessary accessories like arrows, a quiver, an arm protector and a finger tab. It also comes with a right-handed arrow rest (an archer is right-handed if he or she holds the bow with the left hand and pulls the string with the right hand). If the archer is left-handed, you should include a left-handed arrow rest with your order.
