Perun

Perun is a Polish airsoft electronics brand founded in 2016 with a single mission: to design and manufacture MOSFET and ETU (Electronic Trigger Unit) modules for AEG airsoft replicas at a level previously reserved for Japanese manufacturers and expensive premium solutions. The brand takes its name from the Slavic god of thunder — an apt reflection of its products: fast, precise, and ready for any condition. The entire design process and a significant portion of production take place in Poland, enabling a level of quality control that overseas outsourcing simply cannot match. Today, Perun is a recognized name in the global airsoft community, particularly among advanced players and technicians who service replicas.

History and Product Philosophy

Perun's founders entered the market at a time when electronic trigger units were becoming increasingly sought after by players looking to eliminate the drawbacks of mechanical contacts in AEG gearboxes. Traditional AEGs use mechanical contacts to control the motor — contacts that arc, wear down, and limit rate of fire. A MOSFET replaces them with a low-resistance transistor, eliminating arcing, extending contact life, and enabling electronic control over the replica's functions. Perun went a step further by designing the Hybrid line, which combines a MOSFET with an advanced ETU and an optional optical or magnetic sensor in place of a mechanical trigger contact.

Flagship Products — the Hybrid Series

The centerpiece of the brand is the Perun V2 Hybrid and V3 Hybrid series — advanced MOSFET/ETU modules for V2 and V3 gearboxes (the most widely used AEG platforms). The module replaces mechanical contacts with optical or magnetic sensors, eliminating mechanical trigger wear. Programmable features — configured through simple selector switch sequences and trigger pulls, with no computer required — include: precocking (spring pre-compression for a shorter trigger pull), active braking (motor braking after each shot), DMR mode (single-shot restriction), binary trigger (firing on both press and release), ROF reduction, multi-level trigger sensitivity, and LiPo battery protection. Modules are compatible with voltages ranging from 7 to 17V.

Other Products and Accessories

Alongside the flagship Hybrid series, Perun offers the AB++ MOSFET — a compact unit measuring just 14×6×3 mm, making it one of the smallest MOSFETs available on the market. The lineup also includes ETU modules designed for specific platforms such as the Tokyo Marui G28/HK417 and G&G systems. Rounding out the range are accessories: the Perun Clicker (a drum mechanism replacing the trigger contact) and the Perun Speeder — an external component that simplifies precocking without disassembling the gearbox. Further innovations are in development, and the company maintains active communication with the technician and player community, gathering feedback to inform new product design.

Who Perun Is For

Perun products are aimed at technically experienced airsoft players and replica technicians who want to push their AEG's performance to the limit. Perun MOSFETs are especially valued by competitive players who demand reliable, fast, and precise trigger electronics. Technically advanced HPA, DSG, and SSG builders use Perun modules in extreme builds that require electronics capable of handling high voltages and rates of fire.
