Jefftron Active Brake V2 Mosfet - Rear Wired

SKU 35626
  • This Jefftron MOSFET prevents your airsoft gun from potential damage during semi-auto fire mode.

  • It prevents your piston from being stretched, ensures your spring is fully released and generally ensures that the parts in your gearbox are not under strain.

  • This Active brake solves the common issue of multiple shots firing when your gun is in semi mode, often seen in weapons with a very high rate of fire (ROF) or with softer springs.

  • This unit can increase your AEGs rate of fire and offers decreased resistance in the wiring due to the higher quality materials used.
