MechLabs NEXXUS CNC HPA Engine M4/M16 Blue

Designed from the ground up for the V2 2.0 gearbox platform — covering everything from AR-15 replicas to LMGs — Nexxus offers unparalleled performance and ease of use. With no moving electronic components, Nexxus operates exclusively with the air you provide, efficiently delivering up to 800 rounds with a standard 13Ci (3000 PSI) tank.

Nexxus goes further with an ultra-fast and fully adjustable trigger, designed to satisfy even the most demanding players. With SEMI and FULL modes, it perfectly adapts to your playing style. Want a heavier and longer trigger pull? Prefer a shorter pull for semi? Whatever you prefer, Nexxus gives you the option.

You can make these adjustments on the field, thanks to the toolless design of the outer barrel and body. This allows for quick modifications or maintenance, adapting to immediate needs. With an optional tool set (not included), you can even adjust the rate of fire.

It is designed to operate in any conditions encountered by an airsoft player; Nexxus combines maximum durability with enhanced versatility. The body is made from anodized aluminum 6061-T6, while critical parts — such as the nozzle and bolt — have been reinforced and use aerospace-grade aluminum 7075.

· The world's first fully mechanical HPA engine (world-first)
· Anodized aluminum construction (6061-T6) and aerospace-grade aluminum (7075) for critical parts
· Operating range: from very low pressures (~45 PSI) to very high pressures (~200 PSI)
· Integrated physical safety switch
· Integrated quick-release degassing system for safe and rapid tank changes
· Adjustable trigger (distance/travel and weight) via a magnet-based system
· Magnetic trigger return and detachable trigger guard
· Compatible with most common brands (Tokyo Marui, VFC, etc.) and customization components (e.g., MaxxModel hop-ups)
· Ambidextrous magazine release
· Easy installation and maintenance due to the toolless design

IMPORTANT
Due to the large volume of air required for the proper operation of Nexxus in FULL mode (automatic fire), using a FLO MAX regulator is mandatory for stable full-auto operation. If full-auto is used without this regulator, pressure drops and/or other instabilities may occur.

In SEMI mode, Nexxus can operate with any standard regulator.
