Product Details
✓The Perun AB++ is an on-wire MOSFET, channeling the power from the battery to the motor through a specialized high-power transistor, instead of delicate mechanical switches.
✓Perun AB++ increases the reliability and performance of your Airsoft gun and also enhances it by adding many new, useful features. Compatible with the Majority of AEG Gearboxes on the Market. Works with 7.4V, 11.1V and 14.8V batteries. Comes almost fully pre-wired, with only few easy soldering joints needed to install the MOSFET.
✓Programmable Firing Modes with independent select fire modes allowing safe, semi, burst or auto firing on both selector positions. Reduce the rate of fire in automatic or burst fire to save ammo or make the AEG shoot in a more realistic fashion or Adjust intervals between semiautomatic shots to comply with DMR rules on some fields.
✓Active Braking mode to prevent over spin on airsoft rifles with High Rate of Fire by stopping the motor and keeping the spring out of compression after each BB fired.
✓Built in Low Battery Voltage Alarm that provides sound feedback when the battery is low and Built in Diagnostic System that constantly monitors the status of the Mosfet/AEG with LED indicators to easily diagnose and solve any problem on or off the field.
✓Professional Installation is highly recommended for the Perun AB++ as soldering is required and modification of existing wires in the gearbox.
