Specna Arms RETRO Sten MK.II S X-ASR Tracer AEG Submachine Gun - Grey

Electric replica of the Sten MK II submachine gun (S) Special Purpose from the RETRO line, developed in collaboration with manufacturers S&T/AGM. This series focuses on faithfully recreating historic firearms designs, offering models inspired by solutions from past decades.

The MK II (S) model is one of the most recognizable variants of this design, building on the basic Sten MK II and most notably featuring an integrated suppressor. The weapon was developed for the British Special Operations Executive (SOE) for covert and sabotage missions.

The pistol is constructed primarily from metal, ensuring durability and resistance to intense use. Steel has been used for key components such as the receiver, stock, magazine well, charging handle, trigger guard, and mechanical sights.

The use of metal components in critical areas delivers strength and reduces the risk of damage during use. This combination of materials ensures rigidity and stability during firing while maintaining the authentic proportions and character of a historical replica.

The replica retains the Sten’s distinctive, minimalist design based on a tubular receiver, which forms the core of the build. At the front, there is a suppressor, the hallmark of the MK II (S) version. The cover is fitted with a fabric sleeve in brown, enhancing the grip.

The magazine is side-mounted, a typical feature of this weapon and one that defines the replica’s characteristic profile. At the rear, there is a simple, lightweight stock, minimizing the weight while maintaining adequate strength.

The replica operates on electric power, features a full-auto firing mode, and is equipped with a gearbox v7. This system ensures stable mechanism operation and smooth performance.

Inside you’ll find:

• adjustable Hop-Up system – allows you to set BB trajectory according to their weight and environmental conditions, resulting in more consistent shot accuracy
• 330 mm inner barrel – which stabilizes the flight path

The replica achieves a muzzle velocity of approximately 400 FPS. The combination of electric drive, adjustable Hop-Up and optimally sized inner barrel delivers stable operating parameters and consistent shot performance.

The replica comes complete with a tracer for illuminating fluorescent BBs, making them more visible in flight. This makes it easier to track shots and navigate during low-light gameplay.

Additionally, the device simulates muzzle flash, enhancing realism and visual impact, especially for night games. The tracer is powered by a built-in battery and includes a USB-C cable for convenient charging.

The model includes a MOSFET X-ASR system that protects and optimizes the electrical system of the replica. This module protects components from overload, reducing wear and extending the overall lifespan. It also improves trigger response, shortening the interval between pulling the trigger and firing a shot. This results in a more immediate and reliable shooting experience.

Additionally, the MOSFET enables more efficient battery use, minimizing power loss and stabilizing drivetrain performance. Built-in indicator LEDs allow diagnosis of basic faults by alerting the user to potential electronic problems.

The replica is powered by a battery connected via a DEANS/T-connect connector. The set includes a Mid-Cap magazine with a capacity of 120 BBs.
