The MONSTER type hop-up bucking has been specially designed to significantly improve the shooting range.

Its secret lies in the innovative shape of the element that spins the BB - "DIAMOND". This formation on the inside of the Hop Up rubber steers the ball into a straight and constant trajectory through contact with the BB. This increases the precision.

Due to the narrower mouth, this hop up rubber ensures a better seal. Therefore, installing this tuning hop up rubber can increase the performance of the airsoft.
