If you're running an SMG-5, M4/AR-15 or any other AEG which uses a version 2 gearbox, the GATE ASTER™ MOSFET will take your AEG to the next level. This advanced electronic trigger unit replaces your conventional trigger contacts with optical sensors, allowing for 250 different trigger sensitivity settings, burst and binary fire modes and a plethora of other functions to be programmed in using either the trigger and fire selector or the Gate Control Station App. 

This is the MOSFET we use in our Bolster Tuned platforms due to its fantastic balance of cost-effectiveness and performance, offering incredible efficiency improvements even before you get into the programmable features and customisation options. As with all ETU/MOSFET systems, a certain amount of expertise will be required to install the ASTER™ so if you're not confident, we suggest seeking a technician to carry out the installation process for you. If you're ready to take your AEG's performance to the next level, you're ready for the ASTER™!

This meticulous manufacturing ensures a notably quieter gear mesh sound, even under higher FPS and fire rate conditions.

These are 13:1 high-speed gears, improving rate of fire and trigger response by cycling the gearbox once every 13 motor revolutions as opposed to the standard once per 18 revolutions. This means you can boost rate of fire without upgrading your motor, though like any other replacement gearsets, these will require expertise to install. If you already upgraded your motor, wiring and added a MOSFET and you still want more speed, this gearset will do the trick.
