- ETU & Trigger set
- For V3 Gearbox (AKs only)
- Programmable fire modes & pre-cocking
If you need a cheap ETU to give your AK advanced features, the Specna Arms HAL™ ETU for V3 Gearbox is a fine choice. A pre-wired Electronic Trigger Unit (ETU) equipped with a Deans battery connector, the HAL™ is designed to fit version 3 gearboxes, and the included trigger is designed for AK AEGs. Due to the magnetic trigger sensor, the included trigger must be used for the HAL to work. As such, this is only compatible with AK AEGs.
With the HAL™ installed, you can access programmable fire modes, including 3 or 5-round burst, binary trigger, semi-auto only, sniper delay and AUG mode (two-stage trigger). The HAL™ also allows you to set pre-cocking to one of 5 levels, letting you crank up trigger response to near-instantaneous. All programming instructions are carried out using the trigger and fire selector, and instructions can be found on the Specna Arms website. The HAL™ requires expertise to install, so if you're unsure, we recommend consulting a technician.

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.
