This hopup is suitable for use with all blasters that have an oversized barrel, Simply attach the hopup directly to the 9.5mm barrel
A hopup creates a backspin on the gel ball which gives a much higher travel distance, The backspin also increases the accuracy of the blaster significantly!
Please note: If your blaster has a higher FPS of 300 it will not be compatible
