150 LBS - 248 FPS. The Man Kung MK-XB001B crossbow is Man Kung's entry model in the compound range. Compound crossbows are featured with a drawing system of cables and cams which work like pulleys. This system makes it possible to tension the stiff limbs with almost the same draw weight as a recurve crossbow like the MK-150A3B. Just like that crossbow, this model is featured with a thumbhole stock so you can better control the trigger. It is also equipped with an automatic safety, a foot stirrup and an adjustable sight. Because of its severe power, this crossbow is especially suitable for advanced shooters.
