Gate X-ASR is the first 4th generation MOSFET circuit on the airsoft market, featuring reverse polarity protection. In other words, the X-ASR MOSFET is protected against incorrect connection of the battery’s positive and negative terminals to the MOSFET circuit. The X-ASR’s built-in automatic fuse and extremely compact size save space in the airsoft gun’s battery compartment. The X-ASR’s features improve the safety and durability of the electric gun in case of failure, as the X-ASR detects malfunctions using its built-in self-test function and notifies the user with an error code via two LEDs.
X-ASR is a versatile MOSFET circuit designed for use with springs up to M120. When paired with higher torque gears or a stronger motor, the X-ASR MOSFET can also be used with heavier springs.
X-ASR Special Features
- Built-in fuse – allows you to remove the bulky standard fuse from the AEG’s electrical system

- Overheat protection – safeguards the MOSFET from overly heavy AEG setups
- Automatic reverse polarity protection – protects the MOSFET and other components from incorrect battery connection
- Built-in gun condition test program – “self-test” indicates possible faults with two LED lights when an issue occurs
- Durable protective coating – meets the MIL-V-173C standard for military-grade electronics
Package Includes:
- X-ASR MOSFET unit
- Installation instructions and accessories
- “X-ASR Troubleshooting Card” – error code reference card

SMART AUTOMATIC FUSE
An intelligent electronic fuse equipped with voltage, current, and temperature sensors. The fuse continuously monitors the current, voltage, and temperature of the circuit. It protects the system from overload and automatically cuts power in case of a fault or excessive load.

MOSFET
Want short semi-auto response and a high rate of fire from your airsoft gun? A MOSFET circuit improves exactly these features!
The MOSFET directs power straight from the battery to the motor, bypassing mechanical switch contacts. This reduces electrical resistance in the gun’s wiring, lowering power consumption and improving efficiency.

CONTACT BOUNCE FILTERING
The X-ASR circuit filters out contact bounce from the gun’s switch surfaces. This enables flawless operation of micro-switches that are prone to vibration in airsoft guns. Normally, switches may briefly disconnect during the cycle, causing the motor to lose power. Contact bounce filtering improves motor performance and reduces heat build-up.

BUILT-IN SELF TEST
The self-test checks the proper functioning of the gun’s electrical components every time the battery is connected.

PROTECTIVE COATING
The circuit is protected with a military-grade coating that ensures reliable operation in all conditions (Military Specification MIL-V-173C).
