STEN MK2 SOE Loop Stock Full Steel Submachine Gun Replica - Grey [AGM]

The STEN Mk II (S) Special Purpose AEG replica by AGM is a unique construction inspired by one of the most iconic firearms of World War II, designed with special operations in mind. The model replicates the “S" (Special Purpose) version, equipped with an integrated suppressor, used by SOE special forces for covert missions. Its raw, minimalist design and long suppressed front give the replica a distinctive historical character that sets it apart from modern platforms. It is worth noting that the STEN Mk II (S) was one of the most widely used suppressed submachine guns before the era of the MP5SD, highlighting its importance in the history of special operations.

Special operations heritage

The STEN Mk II was developed in response to the shortage of weapons following the Dunkirk evacuation, when British forces urgently needed a simple and inexpensive submachine gun. The design was heavily simplified, allowing for rapid mass production. The Mk II (S) version was a development of this platform, adapted for special operations, equipped with an integrated suppressor and a modified barrel to reduce the sound signature.

This design was widely used by British Commando units during special operations across Europe, including Scandinavia in the 1940s. In later decades, it also saw use beyond Europe, being deployed in covert operations in Southeast Asia, including missions in the Cambodia-Vietnam border region during the 1960s. Interestingly, the platform remained in service even later, finding its way into the equipment of special units in Asia, including combat diver units.

STEN, the shadow weapon of World War II

The STEN Mk II (S) was designed for covert operations - quiet, simple, and effective at short range. The airsoft version retains the key features of the original, including the integrated suppressor (mock suppressor), the distinctive side-mounted magazine, and the minimalist steel construction.

The “S" designation refers directly to the suppressor, which is an integral part of the design. The set also includes a suppressor cover with a retaining cord, faithfully replicating solutions used in the original firearm.

Thanks to this, the replica fits perfectly into World War II loadouts, historical reenactments, and milsim scenarios. It is also an excellent choice for players who appreciate unique, atmospheric designs and a stealth-oriented playstyle.

Raw steel and uncompromising construction

The replica is made almost entirely of steel, except for the aluminum suppressor, ensuring a high level of realism, proper weight, and excellent durability. The raw finish and simplicity of the construction reflect the character of the original firearm, which was designed for practicality and ease of production.

The integrated suppressor features a removable end cap and a fabric-style cover, further enhancing the historical appearance. Inside, there is also an integrated tracer unit with a muzzle flash effect, significantly increasing immersion during gameplay.

Additionally, the design allows the battery to be placed in the front section of the replica, inside the suppressor, which is characteristic of this platform.

Mechanism and performance in practice

At the heart of the replica is a dedicated V7 gearbox, known from platforms such as the M14, ensuring stable and smooth operation. Inside, steel gears and durable internal components are used, providing reliable performance and good operating culture. The system runs on 6 mm metal slide bearings, which increase durability and resistance to wear.

The replica is equipped with an adjustable hop-up system, allowing precise control over BB trajectory and improving effectiveness at medium range. Inside, there is a precision aluminum inner barrel measuring 330 mm in length with a 6.02 mm diameter, which enhances accuracy and shot consistency.

Thanks to its proper balance and moderate rate of fire, the model fits well within historical realism and milsim scenarios. The STEN Mk II (S) performs best in covert operations, where atmosphere, precision, and low visual signature matter - both in night games and historical scenarios.
