Product description
Complete Rotary CNC Hop-Up Chamber for M4/M16 Replicas
A high-quality Hop-Up chamber made by 5KU. The chamber was made entirely from a single block of aluminum with the use of precise CNC machines.
The use of a rotary, aluminum chamber will allow for achievement of much better stability and tightness of the system than at stock, which directly results in better performance and even increase the FPS values.
The set includes all parts and accessories necessary for installation.
