Mechlabs Nexxus HPA Engine for M4/M16 Airsoft AEG Teal

Mechlabs brings you the Nexxus series engine for the M4/AR15 platform. The Nexxus is a fully mechanical engine capable of firing in semi-auto and full-auto mode with the flip of a switch. It requires no batteries, just attach your HPA tank and you're ready to fire. It also features an ultra-fast trigger pull and is highly efficient in the air for up to 3000+ shots with a full 48/4500 tank. The Nexxus engine comes ready to be attached to your external HPA regulator setup, but if you wish to use a shoulder stock tank, we have a kit that has a built-in regulator. Get on board the HPA revolution with Mechlabs!
