Maxx Model Products M4I-PRO CNC Hop-Up chamber for M4/M16 ICS replicas

Engineered specifically for M4/M16 carbine replicas by ICS, the rotary Hop-Up chamber is constructed from aircraft-grade aluminum and precisely CNC-machined. Produced by Maxx Model Products, a respected manufacturer of premium tuning components for ASG replicas.

Offering fine-tuned Hop-up levers and 4mm Bucking Nubs, the chamber guarantees smooth compatibility with both standard and R-hop buckings. A removable steel Pin Pivot allows for simplified maintenance procedures. Compatibility extends to nozzles measuring between 21.00mm and 21.25mm in length. Dual compression springs ensure stable and secure retention within the replica, while the CNC Delrin Locking Clip minimizes barrel movement and vibration. An upgraded BB Latching System retains BBs in the chamber following magazine removal. A tracer unit may also be installed if desired.
