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 (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 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 BB 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. (Inlet Adaptor OD11.5mm and OD12mm 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 M4A 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.

Fps è orgogliosa di presentare la propria linea di canne interne di precisione in acciaio inossidabile 100% MADE IN ITALY.

Questa inner barrel viene prodotta partendo da un micro tubo in acciaio inox di precisione trafilato che viene successivamente sottoposto alle seguenti lavorazioni:

- tornitura CNC

- rettifica lineare

- alesatura interna

- lappatura

- brillantatura ad ultrasuoni

La forma della finestra hop-up è stata studiata per essere compatibile sia con gommini normali che con quelli di tipo “flat”.

Il materiale utilizzato assicura massima resistenza meccanica e assenza totale di ossidazione superficiale diversamente dall'alluminio o dall'ottone.

Altro grande vantaggio dell'acciaio inox è quello di poter essere tranquillamente pulito con spazzole metalliche senza subire graffiature, assicurando così la più completa rimozione di eventuali residui plastici presenti sulla superficie interna del foro.

Dati tecnici:

- diametro interno: 6.03 mm

- diametro esterno: 8.51 mm

- materiale: acciaio inox AISI 304
