NexxSpeed CNC Aluminum Hop Up Chamber Version 2 For AEG M4 Airsoft Series

The Arm-Press Design on the Nub uses steel plates of different thicknesses to form the desired elasticity, helping to improve BB accuracy and consistency. It also comes with 3 different types of aluminum nubs.

Gearbox Input Adapter:
The input adapter can be swapped to match different outer diameters—OD 12 mm / OD 11.5 mm / OD 11 mm—to ensure the hop-up unit is mounted precisely at the center of the nozzle outlet on the AEG gearbox / HPA engine.

FPS Performance:
Compared to the stock setup, FPS can be increased by approximately 10–30 FPS.

Compatibility:
The CNC aluminum hop-up chamber is precision-machined to operate accurately and consistently on the Tokyo Marui platform, including (but not limited to) G&G and KRYTAC standard M4/M16 AEG, ICS CXP/CS4/EBB (including older models), and HPA PolarStar engines on the standard M4/M16 platform.

Version 2 Update: Added a BB-holding function for more stable feeding.

Compatible with: M4 AEG Airsoft
