A drop in MOSFET Kit designed for Version 3 Gearbox, which are typically seen in AK and RPK Variant Rifles.

Full description


The board is specially coated with Mil-Spec MIL-V-173C Varnish, making it moisture and fungus resistant, and supports batteries in the range of 3V up to 17v, making it great for Ni-Mh, Ni-Cd, Li-Po, and Li-Fe Batteries and is compatible with most V3 Gearbox on the market with no modification. The Titan Board itself is built in the EU by Gate Electronics, and comes with a 12 Months Manufacturer Warranty for defects and stands out from the crowd due to its Optical Sensor Controlled System rather than Mechanical ,and has Eight Onboard Optical Sensors. The board boasts a huge array of features, with the most impressive being the Auto-Adjusting pre-cocking and breaking system, using the on-board sensors to detect the position of the Gearbox's Gear's Teeth, allowing the system to get a perfect result with almost no configuration. The board itself, once installed, is capable of very fast repeated semi-shots, with gearbox protection ignoring the trigger pull if the rifle is not ready, allowing for faster, more consistent shots compared to other units. Once installed the included MOSFET unit can be re-programmed via the Gate Configuration Card or via the USB-Link to a PC, Laptop, and even Mobile Phones, allowing the firmware to be updated, and can be used to Error Check your Weapon should something go wrong. Whats important to highlight with the Titan, is that its strength lies not just in its list of features, but also in how well they've been implemented. For more information on this Gate MOSFET, please see the extensive list of features in the Features Section. Should you need any help installing the MOSFET please feel free to call our workshop on: 01484 644709.

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.
