Perun G&G ETU++ Upgrade Kit (Deans) - Unlock the True Potential of Your G&G Rifle

If you own a G&G rifle equipped with the factory ETU and MOSFET - you already have a solid foundation - but the Perun ETU++ is the key to unlocking its full potential. This is a direct "plug-and-play" replacement for the standard G&G electronic trigger unit - offering a massive leap in functionality and reliability. By simply swapping the unit - you gain access to a suite of advanced features like Pre-Cocking - Active Brake - and custom fire modes - all without needing to open your gearbox or void your warranty. It is the single most effective "brain" upgrade you can give your G&G platform.

Key Features and Performance

• Total Plug-and-Play Simplicity - Replaces the original G&G MOSFET in seconds - fitting neatly into the buffer tube or stock with no soldering required.
• Adjustable Pre-Cocking - Keeps the piston in the rearward position for instantaneous trigger response - giving you the edge in fast-paced CQB exchanges.
• Binary Trigger Mode - Allows the rifle to fire once on the pull and once on the release of the trigger - effectively doubling your semi-auto rate of fire.
• Active Brake and Li-Po Protection - Prevents motor over-spin to protect your internals and monitors your battery voltage to ensure your Li-Pos stay healthy.
• Deans Connector as Standard - Comes pre-fitted with a high-current Deans (T-Plug) for reduced electrical resistance and better efficiency.

The "Pro" Take

The beauty of the Perun ETU++ lies in its programming simplicity. Unlike other high-end units that require a PC or a smartphone app - the ETU++ is programmed via the trigger and a multi-coloured LED on the unit itself. This is a lifesaver when you are in the safe zone and need to adjust your Pre-Cocking or turn off your "Burst" mode between games. It is incredibly robust and fixes the "crunchy" or inconsistent trigger feel sometimes found in stock G&G units. For the G&G ARP9 or CM16 Raider 2.0 owner - this is arguably the best "bang-for-buck" upgrade available on the market today.

UK Spec and Site Performance

For UK players - the ETU++ is a game-changer for semi-auto dominance. Since most UK woodland sites have strict "Semi-Auto Only" rules within buildings - and many CQB sites are semi-only throughout - the Pre-Cocking feature ensures your BB leaves the barrel the micro-second you touch the trigger. This removes the "lag" often associated with standard AEG setups.

Additionally - the ETU++ is fully compatible with 7.4v and 11.1v Li-Po batteries - which is vital for the UK climate where cold winter mornings can sap battery performance. The built-in electronic fuse will also protect your motor and gears if a jam occurs - a common occurrence if you are using lower-quality "bio" BBs required by many UK outdoor sites. It keeps your rifle within site limits while making it feel twice as responsive.

Friendly FAQ

Do I need to open the gearbox to install this?
No - that is the best part! The ETU++ replaces the external MOSFET unit located in the wiring loom (usually found in the stock or buffer tube). You simply unplug the old G&G unit and plug in the Perun.

Will this work with my specific G&G model?
It is designed for any G&G rifle that already has the factory-installed ETU and MOSFET system. This includes the ARP9 - ARP556 - CM16 Raider 2.0 - and many of the GC16 series.

Can I still use my 3-round burst?
Yes - and much more. You can program any fire mode combination you like on both the "Semi" and "Auto" selector positions - including 2 to 5 round bursts - or even semi-only for DMR builds.

Does this kit include the Deans adapter?
The unit comes with a Deans connector already soldered on. If your batteries still use the old Tamiya style - you will need to switch your batteries to Deans to take full advantage of the lower resistance.
