Sig Sauer x SIG Air MCX Series Mosfet and Wire - Pro Force

Maintain ultimate electrical performance and protect your rifle's trigger system with the Sig Sauer x SIG Air MCX Series Mosfet and Wire - Pro Force. Engineered by VFC under official license from SIG AIR, this factory-original replacement wiring harness and inline MOSFET unit is built to drop seamlessly into the SIG Sauer MCX Virtus AEG series, providing seamless electrical flow and long-term switch protection.

Switch-Protection MOSFET & Low-Resistance Wiring

The core feature of this MCX Pro Force Wiring Assembly is its integrated inline MOSFET unit. By routing electrical current directly from your battery to the high-torque motor, the MOSFET bypasses high-voltage loads away from delicate mechanical trigger switch contacts. This eliminates electrical arcing, carbon buildup, and contact burnout when running performance batteries. Wrapped in low-resistance thermal insulation, the pre-soldered wiring harness minimizes electrical resistance, maximizing energy transfer from your battery to the motor for crisp semi-automatic trigger action and smooth cycle speed.

OEM Drop-In Compatibility & Reliable Performance

Built specifically to fit inside the tight dimensions of the SIG MCX Virtus receiver and battery compartment, this factory wire set features correct wire lengths and pre-installed connectors. This eliminates the need for custom soldering, cutting, or shrink-wrapping during gearbox maintenance. Whether you are replacing worn stock wiring or repairing a damaged contact set, this OEM component ensures complete mechanical and electrical alignment with your VFC Avalon V2 gearbox shell.

Tactical Utility & Real-World Use Cases

Upgrading or replacing your MCX electrical harness with this official module delivers key advantages for high-performance builds:

• LiPo Battery Upgrades (11.1V Preparedness): Protects trigger switch contacts from frying or arcing when running high-discharge 11.1V LiPo batteries for elevated rates of fire.

• Gearbox Maintenance & Repair: Restores dead or intermittent electrical connections caused by pinched wires, damaged insulation, or worn factory trigger switches during routine tech work.

• High-Speed Semi-Auto CQB Play: Ensures instant single-shot trigger response by delivering uninterrupted current flow to the motor during rapid trigger pulling in tight indoor arenas.

Key Features & Technical Benefits:

• Official Factory OEM Component: Direct drop-in fit for the SIG AIR / VFC MCX Virtus Pro Force AEG series.

• Integrated Inline MOSFET: Protects mechanical trigger contacts against electrical arcing and heat degradation.

• Low-Resistance Electrical Wiring: Delivers efficient battery-to-motor power transfer for crisp trigger response.

• Pre-Soldered Assembly: Factory-fitted connectors reduce installation time without requiring custom soldering.

• LiPo Battery Ready: Optimizes electrical flow for safe operation with high-voltage 7.4V and 11.1V LiPo setups.
