STEN MK2 Full Steel AEG - Iconic British WWII Submachine Gun
Searching for a STEN MK2? This is a fully legal 1:1 scale airsoft replica — the same silhouette, size and feel as the historic weapon, but no firearms permit required in most EU countries. Owning a real STEN MK2 typically means a certified gun safe, background checks and €1,500–€4,000+ for a collectable original. This replica costs a fraction of that, ships across the EU, and is the fastest legal way to own an accurate copy of this gun for display, historical re-enactment, airsoft skirmish, or as a learning piece. Note: airsoft laws vary by country — it is the buyer's responsibility to confirm that owning an airsoft replica is legal where they live before purchasing.
The STEN MK2 airsoft submachine gun faithfully recreates one of the most recognisable Allied weapons of the Second World War. Born of necessity after the Dunkirk evacuation, the original STEN was famously simple, rugged and fast to produce - a single worker could assemble a complete weapon in just a few hours. This airsoft replica captures that no-nonsense character with a full-steel build, side-mounted magazine well and the unmistakable tubular receiver of the 1940s era.
Full steel construction - heavy, authentic, durable
Like the original, the replica is built mainly from steel. Steel parts include the outer barrel, heat shield, receiver, magazine well, magazine, trigger guard and stock plates. Only the stock tube is aluminium. The result is a 2,650 g (2.65 kg) replica with the balance, weight and rattle of the real thing - exactly what re-enactors and WWII collectors expect.
V7 gearbox and 6.03 mm precision inner barrel
Inside sits a reinforced metal Version 7 (V7) gearbox with steel gears on 8 mm brass sliding bearings - a robust SMG-specific design. The 229 mm precision inner barrel uses a 6.03 mm tightbore for consistent grouping, and the adjustable hop-up can be tuned to your preferred BB weight. Muzzle velocity sits at approximately 350 FPS / 107 m/s with 0.20 g BBs, delivering about 1.14 J - well-suited for CQB and mid-range field use.
Full-auto only - historically correct
The real STEN fired only in full-auto, and so does this replica. The 40–50 round mid-cap steel magazine is included; it shares the same magwell pattern as MP40-type magazines, so spares are easy to source. The battery compartment is hidden inside the fixed stock and accessed via an Allen-key bolt - there is no external wiring or visible mock-up.

Building a WWII loadout? Pair the STEN with the British service rifle, the Lee-Enfield SMLE shell-ejecting rifle or the later Lee-Enfield No. 4 Mk I. For the Allied sniper role, see the Mosin-Nagant 1891/30 PU sniper. For German opposition, the Kar98k real wood and the Kar98 polymer complete the era.
