Maxx Model Products M4E Aluminum Hop-Up Chamber for M4/M16 replicas

Rotary Hop-Up chamber designed for Tokyo Marui standard M4/M16 replicas. The chamber is crafted from a block of aircraft-grade aluminum and precisely machined using CNC technology.

Compatible with both standard and R-hop rubber bands. The CNC Delrin Locking C-Clip system prevents the barrel from vibrating or shifting. Two compression springs provide secure and stable chamber positioning inside the replica. The brass Slot Pin is easily detachable for convenient setup and maintenance. Additionally, there is an option to install a BBs illumination module and a sensor that halts the motor or HPA system when the magazine is empty. An O-ring on the pressure arm further enhances stability and smooth operation.
