The Hop-Up Chamber M4E unit by MAXX Model is engineered to eliminate jamming and double feeding while ensuring that BBs line up straight and consistent 95% of the time. The design features o-rings instead of screws for the hop-up arm, securely holding the pivot pin. Its internal structure has been updated for tighter tolerances, enhancing overall consistency and accuracy.
Crafted from CNC aluminum, the M4E Hop-Up Chamber (with BB Latching System) is precisely machined for reliable performance with Tokyo Marui-standard M4/M16 AEG series rifles, including G&G and KRYTAC models (excluding KWA).
This unit includes an aluminum rotary dial knob for fine hop-up adjustments, a precision hop-up lever, and 4mm bucking nubs optimized for R-Hop and standard-hop setups, ensuring accurate and consistent BB shooting.
The Hop-Up Chamber M4E accommodates nozzle lengths from 21.00mm to 21.25mm and is compatible with most aftermarket soft and hard rubber buckings, maintaining FPS without dropping BBs.
It features an interchangeable Inlet Adaptor (OD 11mm) to ensure precise alignment in the 11mm inner bore of AEG gearboxes or HPA engine nozzle outlets, eliminating wobble. Removable CNC brass side wings allow for smooth installation into outer barrel slots, while an advanced CNC Delrin locking C-clip secures the inner barrel tightly to prevent wobbling and twisting.
Additionally, the M4E unit includes a new BB Latching System that prevents BBs from falling out when the magazine is removed. The Latching Arm can be manually pressed to release any remaining BBs from the hop-up chamber.
