FIRST FACTORY TM GBB M4 Strike Hop Arm

Tokyo Marui GBB M4 is known for its stability and precision, but with the original cam the Hop tends to be weak and lacks performance for long distance shots. We redesigned the shape of the cam to get a better and stronger Hop up compared to the original configuration. Features: · For strong Hop and long-range enhancement · Material: CNC Aluminum Alloy · Compatible with Tokyo Marui M4 GBB series
