Maximize the power of your railgun by converting it to an roller speargun. This kit can add about 40cm of power to your railgun. For example if you shoot a 70cm traditional railgun...after this conversion your speargun will have the power of a traditional 110cm speargun. At the same time, the pulley system will decrease recoil to almost zero!
