Specna Arms Sten MK.II(S) RETRO AEG submachine gun (X-ASR/Tracer)
The Specna Arms: Retro range was developed in collaboration with S&T/AGM. It is a series of classic historical replicas, designed for enthusiasts of iconic designs from past decades. Models in this range faithfully reproduce the appearance of the original weapons, making them ideal for historical re-enactments and an excellent choice for enthusiasts of historical firearm replicas.
The Tracer included in the set allows you to illuminate fluorescent BBs and simulate the flash of a shot, which enhances the gameplay experience. This looks particularly impressive during night-time games. The set also includes a USB-C cable for charging the device.
The top-quality X-ASR MOSFET ensures the safety of the replica’s components, improves trigger response and extends the service life of the electronics and battery, whilst also enabling the diagnosis of basic faults inside the replica thanks to the built-in indicator LEDs.
The British STEN MK.II (S) –Special Purpose – submachine gun was developed for the British SOE for special operations behind enemy lines – not only in Europe, but also in the Far East. Interestingly, the silenced version remained in use long after the end of the Second World War.
