Maxx-i CNC Alumiinium hopikamber M4i - PRO

CNC Aluminum Hopup Chamber M4i Pro (with BB Latching System) unit is precisely machined to perform accurately and consistently on ICS CXP/CS4/EBB (include old models) M4/M16 AEG series.

The Hopup Chamber M4i unit is built with an aluminum Rotary Dial Knob for fine hopup adjustments, the precision Hopup Lever and 4mm Bucking Nubs (6mm Bucking Nubs are optional) to perform best with R-Hop and Standard-Hop to keep the BB shooting accurately and consistently on every single shot.

The Hopup Chamber M4i unit is designed to accept 21.00mm to 21.25mm nozzle length, and fully compatible with most aftermarket soft and hard rubber buckings without losing FPS or dropping BB during use.

The Hopup Chamber M4i unit is wisely equipped with an interchangeable Inlet Adaptor OD12mm to ensure the hopup unit is inserted exactly in the center of the 12mm inner bore ICS AEG Gearbox nozzle outlet without wobbling. (Inlet Adaptor OD11mm and OD11.5mm are optional)

Also mounted the removable CNC Brass Side Wings to slide smoothly into the outer barrel slots, and included an advanced CNC Delrin Locking C-Clip to hold the inner barrel tight in place without wobbling and twisting.

More than that, the Hopup Chamber M4i Pro unit is specially designed with a new BB Latching System to prevent BB dropping after removing the magazine. The Latching Arm can also be manually pressed to release the remaining BB from inside the hopup chamber.
