The Jefftron wire holder simplifies one of the trickiest steps in fitting a Leviathan-V2 optical unit: managing wiring during gearbox reassembly. These small but essential tools hold your wires firmly in place so they don’t snag, twist, or get trapped when you’re closing the gearbox.
Key Features
- Set of 2 holders – enough for most single-gearbox builds
- Designed specifically for Leviathan-V2 optical units
- Holds wiring securely during assembly, reducing frustration
- Compatible with standard gearboxes and Retroarms designs
- Adjustable – holders can be enlarged slightly with pliers for wider wire channels
- Lightweight and non-invasive to gearbox function
Real-World Use Cases
Whether you’re a tech-savvy skirmisher upgrading an AEG or a milsim player installing an optical mosfet, the Leviathan-V2 is powerful but fiddly to fit. These holders are especially valuable if you’re working in tight spaces or with reinforced gearboxes like Retroarms shells, where wire routing becomes critical. They’re also handy for anyone who’s had to disassemble and reassemble a gearbox multiple times during tuning.
Technical Specifications
- Quantity: 2 holders per pack
- Designed for: Leviathan-V2 optical mosfet
- Material: Durable polymer
- Adjustability: Enlargeable with standard pliers
Compatibility & Upgrades
These holders work with any gearbox housing compatible with the Leviathan-V2 optical unit. For non-standard or Retroarms gearboxes with wider wire channels, the holder ends can be carefully enlarged using pliers – Jefftron notes you may need to grind or file a pressure point on the opposite side of the gearbox for optimal grip. Always test fit before full assembly.
UK Legal & Site Notes
Wire holders are internal gearbox components and carry no legal restrictions. They’re purely a build aid and do not alter your AEG’s power, range, or safety characteristics. Check your local skirmish site’s rules on internal modifications if required.
Keep a spare set handy if you regularly service or upgrade your Leviathan-V2 builds. These simple tools save hours of frustration.
