PERUN009
AB++ is an on-wire MOSFET with a specialized high-power transistor that transfers power from the battery directly to the motor instead of fragile mechanical switches. That greatly extends the service life and lowers overall resistance resulting in a more reliable replica with a higher rate of fire which you can shoot longer without changing the battery.

PERUN011
Perun V2 Hybrid replaces mechanical contacts in your airsoft replica or gel blaster and provides lots of useful features. Optical and magnetic sensors allow to eliminate many moving parts that are prone to damage, thus increasing the reliability. Adaptive trigger control allows switching from a very short trigger travel to a long one even in the field,...
