THIS PRODUCT HAS BEEN DISCONTINUED BY THE MANUFACTURER AND HAS BEEN REPLACED BY THE M4A, M4I AND M4P

The Maxx CNC Aluminum Hopup Chamber is specially designed to improve accuracy, durability and ensure consistent air seal for M4/M16 style airsoft AEGs.

The precision rotary dial design for fine hopup adjustments and re-engineered hopup levers and concave nubs are designed to work best with R-hop and Standard-Hop to keep the BBs shooting straight and accurate on every single shot.

Designed to accept nozzle lengths from 21.00mm to 21.25mm, it is fully compatible with most aftermarket soft and hard buckings without losing FPS or dropping BBs.

The Hopup Chamber SV Housing is equipped with a new CNC Delrin Locking C-Clip designed to hold the barrel tight without wobbling and twisting. Three compression springs keep the unit is kept centred, straight and air tight when adapted to a V2 gearbox with 11m or 11.5mm inner bore.

Sport models have an o-ring retention system that prevents unfired BBs in the chamber from dropping out when the magazine is released. Pro units feature a latch which performs the same function but also enables the user to manually release those unfired BBs when storing the AEG.

The optional LED set includes dual UV boards to charge tracer BBs to glow in the dark.
