The Hopup Chamber M4A unit is built with an aluminum rotary dial knob for fine hopup adjustments, the precision hopup lever and 4mm bucking nubs to perform best with R-Hop and standard-hop to keep the BB shooting accurately and consistently on every single shot.The Hopup Chamber M4A 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 BBs during use.
The Hopup Chamber M4A unit is wisely equipped with an interchangeable Inlet Adaptor OD11mm to ensure the hopup unit is inserted exactly in the center of the 11mm inner bore AEG Gearbox/HPA Engine nozzle outlet without wobbling. 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 tightly in place without wobbling and twisting.
Additionally, the Hopup Chamber M4A Pro unit is specially designed with a new BB Latching System to prevent BBs from dropping after removing the magazine. The Latching Arm can also be manually pressed to release the remaining BB from inside the hopup chamber.
