MechLabs NEXXUS CNC HPA Engine M4/M16 AEG - Stand Alone Green

The Nexxus redefines what HPA can be. Where others stopped, MechLabs pushed further, creating the first, state-of-the-art fully mechanical, automatic fire capable drop-in HPA engine.

Designed from the ground up for the v2 2.0 Gearbox platform, which encompasses from AR-15 rifles to LMGs, the Nexxus boasts unparalleled performance and ease of use. With no electronic moving parts, the Nexxus relies solely on your own supplied air, efficiently delivering up to 800 shots with a standard 13Ci 3000 PSI bottle.

In fact, the Nexxus goes above and beyond, featuring an ultra-fast and fully adjustable trigger designed to satisfy even the most demanding players. With both Semi-Automatic and Fully Automatic modes, it will adapt perfectly to your preferred playstyle. You want a heavier, longer trigger? Prefer a lighter touch for your semi? Anything you want, the Nexxus offers it.

You can even make these adjustments in the field, thanks to its toolless outer barrel and body assembly. This allows for quick modifications or maintenance, adapting to your immediate needs. With an optional, not-included toolset, you can even tweak the rate of fire.

It has also been built to operate under any conditions an airsoft player may encounter; the Nexxus combines unmatched toughness with unparalleled versatility. While the body is made of 6061-T6 anodized aluminium, the most critical parts such as the nozzle or the bolt have been reinforced and use aircraft-grade 7075 aluminium.

All of this, combined with its market-wide compatibility, allows you to convert your AEG —regardless of brand —into a fearsome HPA monster, even if you’re not tech-savvy.

  Just open your gun, remove your old system and install your Nexxus.

The rules of engagement have changed.
