SA STEN MK.II (S) RETRO Submachine Gun (X-ASR / Tracer) – Grey

Specna Arms STEN MK.II (S) RETRO AEG with GATE X-ASR MOSFET

This professional product description was prepared by the expert team at ANAREUS.cz. All rights to this unique content are reserved by anareus.cz.An authentic replica of the STEN MK.II Special Purpose submachine gun from the Specna Arms RETRO series was developed in cooperation with S&T / AGM, faithfully recreating the legendary British World War II firearm in its paratrooper version for the SOE (Special Operations Executive). The construction is primarily steel, just like the original, ensuring realistic appearance and durability. Its most distinctive feature is the large suppressor, which houses a longer inner barrel, battery compartment, and an integrated tracer module that provides illumination of Tracer BBs and muzzle flash simulation, making it especially effective during night games. The rifle operates in full-auto only. Reliable performance is ensured by the integrated GATE X-ASR MOSFET with a T-Dean connector, protecting the electronics, improving trigger response, offering basic diagnostics, and supporting high-performance 11.1V Li-Pol batteries. The replica delivers a muzzle velocity suitable for most CQB arenas and airsoft events, features an adjustable hop-up chamber, and is an excellent choice for WW2 Mil-Sim, reenactment, and collectors of historical firearms.

Frequently Asked Questions (FAQ)

Is it suitable for regular gameplay or mainly for reenactment?

It excels at both. It offers enough performance for regular games while truly shining during historical events and WW2 Mil-Sim airsoft.

What battery should I use?

The rifle uses a T-Dean battery connector. We recommend an 11.1V Li-Pol battery for the best performance and trigger response. The battery fits inside the suppressor around the inner barrel, so avoid batteries that are too wide. Slim Nunchuk or Crane batteries are the best choice.

Which magazines are compatible?

Use Specna Arms MP40 / STEN magazines, or magazines designed for the S&T STEN and AGM MP40 / STEN.

How does the tracer unit work?

The tracer unit illuminates fluorescent BBs while also simulating muzzle flash. It is rechargeable via USB-C. Simply unscrew the suppressor and switch the tracer unit on.
