Firefly DENKI UMASHIKA Chu-TORO (Soft) Bucking for AEG

This Hop-Up bucking, made in Japan, is designed to ensure precise BB centering consistency. The bucking's protrusions evenly contact the top of the BB, optimizing precision. The inner design can be seen in the product photos. This Soft type bucking is best suited for lightweight BB's (~.25 or less) at a medium velocity. For best performance, pairing this bucking with the Fire Fly Custom Nozzle and FireFly Namazu Soft Type nub is recommended by the manufacturer. This bucking requires a 300-shot break-in period to achieve optimal accuracy.
