Mechlabs NEXXUS HPA Gearbox for M4/M16 - Black

Designed from the ground up for the V2 2.0 Gearbox platform, which encompasses 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. 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 aluminum, the most critical parts such as the nozzle or the bolt, have been reinforced and use aircraft-grade 7075 aluminum.

Features:

• World-first fully-mechanical HPA engine
• Anodized aluminium and aircraft-grade aluminium build
• Operating range from very low pressures of ~45 PSI to very high pressures of ~200 PSI
• Integrated physical safety switch
• Integrated degassing system for quick and safe bottle swaps
• Adjustable trigger (distance/weight) thanks to a magnet-based system
• Magnetic trigger return and detachable trigger guard
• Ambidextrous magazine release
• Ease of installation and maintenance thanks to a toolless design
• Compatible with the most commonly seen brands (Tokyo Marui, VFC…) and customization brands (such as MaxxModel’s hop-ups)

Warning: Only compatible with Mechlab's HPA regulator series due to the Nexxus engine being too powerful for standard market regulators to enable full functionality.

Disclaimer: As the lubricant used for the Nexxus HPA engine may have solidified due to prolonged idling periods, you may need to break in the engine by dry firing repeatedly IN SEMI-AUTO, NOT FULL-AUTO, in order for its components to cycle.
