If you are looking for an affordable way to add advanced functionality to your M4/AR-15 AEG, this is worth a look! The Delta Armory Programmable ETU Processor Unit for V2 Gearbox replaces your conventional trigger assembly and offers burst mode, binary trigger and pre-cocking, all of which can be programmed in using the fire controls of the AEG itself. 

This ETU should fit most M4/AR-15s which use a version 2 gearbox, but we only recommend this part for experienced techs and those in the know when it comes to Airsoft internal upgrades. The ETU is also pre-wired to a Deans/T-Plug battery connector in rear wired configuration and spade connectors for your motor, so you shouldn't need your soldering iron!

If you are looking to further extend your advantage and push your TM NGRS system to the limits reinforced gears are a must for long term reliability under increased stress. The Laylax EG Hard Gear Set is specifically designed for the Tokyo Marui Next Generation Recoil Shock (NGRS) gearbox and includes a hardened steel spur gear, sector gear and bevel gear. This gearset is a standard ratio set (18:1), intended to provide a great compromise between high speed and high torque, allowing you to take your build in either direction and still benefit from reinforced gears!

If you are looking to further extend your advantage and push your AEG to the limits reinforced gears are a must for long term reliability under increased stress.

If you're looking for an upgraded AEG motor with the best price-to-performance ratio, you're looking for the Warhead Industries Base Brushless Motor! This brushless motor was conceived as a more affordable alternative to the legendary Warhead CNC Black Brushless Motor, boasting similar performance at an unbeatable price point. This, the long shaft variant, is designed for standard M4/AR-15, SMG-5, G3 and P90 AEGs.

Like the Warhead CNC Black motor used in Bolster Armouries builds, the Base boasts an ESC (electronic speed control) module which protects your battery, provides low-voltage cutoff and regulates speed to keep the immense power of the Base under control. The primary difference between the Base and the CNC Black is that the base uses a cast aluminium housing instead of a CNC machined one and the stator is wound via machines while the CNC Black is hand-wound.

The advantages of running a brushless motor are numerous, the most important of which is a far higher torque to weight ratio than conventional motors. The lack of brushes means there is less to go wrong and the motor is far quieter when running, guaranteeing a longer lifespan of smooth running performance. That said, these motors are intended for highly upgraded setups so we only recommend them for those who are confident working on AEG internals. If your custom-built beast needs an equally beastly motor to drive it, the Warhead Base Brushless Motor; Short Shaft is one of the best choices out there!

If you want to transform your version 2 gearbox-equipped AEG into a true "smart gun", the Gate TITAN™ MOSFET V2; Expert Firmware will do exactly that. This advanced MOSFET/ETU system replaces the copper trigger contact inside the version 2 gearbox with optical sensors, eliminating the need for a cut-off lever, extending the lifespan of your AEG and offering unprecedented trigger sensitivity, fire mode and cycle control adjustment options. 

The latest version of the TITAN™ V2 includes the Expert Firmware, meaning you have immediate access to the most advanced programming functions of the TITAN™ without needing to pay more to update the firmware. With the Gate USB-Link or Blulink, you can set your pre-cocking level for a speedy trigger response, adjust your trigger sensitivity, tune active braking and adjust the rate of fire for a truly custom setup that suits your playstyle perfectly. The usual programmable MOSFET functions of other ETUs are also present, including burst mode, binary trigger, semi-auto-only, ramping semi-auto, dual-stage trigger and sniper delay. 

If you have an AEG mega-build on your mind using a version 2 gearbox, add the Gate TITAN™ MOSFET V2; Expert Firmware to your parts list to take it to the next level!
