ShanYe Guyu Upper Rail System

Ever run out of darts during a battle and you need more? or hating to hold a bunch in your hand and loading? Well this convenient rail system helps with that. Not only is it stylish, but it also holds 8 darts. Stuff you will need: four M3x18mm screws and two M3x6mm. Install is pretty simple and self explanatory. Happy foam flinging ya'll.
