This professional product description was prepared by the expert team at ANAREUS.cz. All rights to this unique content are reserved by anareus.cz.This authentic STEN MK.II replica from the Specna Arms RETRO series was developed in cooperation with S&T / AGM and faithfully recreates the legendary British World War II firearm. The construction is primarily made of steel, just like the original, providing both realism and durability. A characteristic feature is the tubular metal STEN MK.II stock, which can be removed by unscrewing it to access the battery compartment. The replica fires in full-auto only. Reliable operation is ensured by the integrated GATE X-ASR MOSFET with a T-Dean connector, protecting the electronics, improving trigger response, providing basic diagnostics, and supporting high-performance 11.1V Li-Pol batteries. The replica offers a muzzle velocity suitable for most CQB arenas and airsoft events, an adjustable hop-up chamber, and is an excellent choice for WW2 MilSim, reenactment, and historical firearms enthusiasts.

Frequently Asked Questions (FAQ)

Is it suitable for regular airsoft games or mainly for reenactment?

Both. It offers sufficient performance for regular skirmishes while truly standing out during historical events and WW2 MilSim games.

What battery does it use?

It uses batteries with a T-Dean connector. We recommend an 11.1V Li-Pol battery for the best performance and trigger response. The battery is installed inside the tubular stock, so choose a battery no wider than 21 mm. Buffer Stick and standard AK Stick batteries fit very well.

Which magazines are compatible?

Use Specna Arms MP40 / STEN magazines, or magazines designed for the S&T STEN and AGM MP40 / STEN. SRC MP40 magazines are not compatible because they use a differently shaped magazine cap.
