- Semi Only MOSFET/ETU
- Adjustable pre-cocking
- Compatible with M4/AR-15 AEG with V2 gearbox
If you are looking for an easy way to make your Airsoft platform exclusively a DMR or CQB beast, this is worth checking out! The Delta Armory Programmable ETU Processor Unit for V2 Gearbox; Semi Only replaces your conventional trigger assembly and offers semi-automatic fire only with adjustable pre-cocking, 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!

Description
This Delta Armory ETU is a great way to add advanced functionality to your M4/AR-15 AEG, along with improving trigger response, improving consistency and ensuring excessive semi-automatic use will not corrode your trigger contacts. The unit replaces the trigger switch and wiring assembly of your M4/AR-15 AEG and is pre-wired to a Deans/T-Plug battery connector in rear wired configuration. The "spade" motor connectors are also pre-wired, meaning you shouldn't need your soldering iron for installation.
When installed, the Delta Armory ETU locks your platform to semi-automatic firing only, perfect for DMRs and CQB-orientated replicas. It also offers pre-cocking, so you can have a snappier trigger response along with the standard improvements in electrical efficiency provided by an electronic trigger.
The user manual of the ETU comes in the form of a QR code sticker pre-fitted to the wiring harness which can be scanned to access detailed instructions. As with all internal upgrade parts, we only recommend this part for users familiar with M4/AR-15 AEG internals and willing to carry out potential modifications.

Parts Fitting
Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff.
Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.
We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!
Unique Parts
Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.
Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.
If you require help with fitting any parts feel free to get in touch with us via our Contact Us Page.
