NorthEast Airsoft STEN Mk.2 Gas Blowback SMG — Chinese Contract / Skeleton Stock

Bring historic battlefield character and modern airsoft performance together with the NorthEast Airsoft STEN Mk.2 Gas Blowback SMG (Chinese Contract / Skeleton Stock). This faithful reproduction captures the look, weight, and handling of the wartime STEN while adding practical upgrades for reliability, gas efficiency, and field serviceability — making it a standout choice for collectors, milsim players, and historical reenactors who want an authentic, ready-to-run SMG.

Authentic construction, modern durability

Built with a full steel structure (breech block is lightweight aluminum alloy) and finished in a durable manganese phosphate coating, the STEN Mk.2 delivers a realistic heft and period-correct appearance without sacrificing corrosion resistance. Authentic stamping marks and the distinctive Chinese-contract magazine markings — including historical characters denoting “STEN” and “Made in Canada” — add ornamental and collectible value while keeping the replica visually faithful to Long Branch wartime production.

Improved internals for longer service life

This is a true second-generation design: NorthEast Airsoft relocated the firing pin base to extend maintenance intervals and redesigned the magazine output seal and nozzle for improved air sealing and longevity. Those upgrades reduce the frequency of parts replacement and improve reliability in the field. The breech block is aluminum alloy to provide a convincing “kick” while keeping overall reciprocating mass manageable — the result is convincing blowback behavior with reduced wear.

Gas-ready, user-focused magazine design

The STEN Mk.2 comes with a purpose-built 32-round stick magazine engineered to resist over-gassing even when the gun is fired from awkward angles. The magazine’s gas tank endplate fastening method has been enhanced for easier, more secure installation of the gas reservoir. Notably, the nozzle design is CO₂ ready, giving users the option for more consistent power in cold or demanding conditions. Important safety note: the manufacturer advises not to fill the magazine with gas for more than 7 seconds — follow this guidance to avoid over-pressurization and potential damage.

Realistic handling and safety features

Field-strippable for maintenance and compact storage, the STEN Mk.2 retains tactile, authentic controls: a bolt hold-open, a cross-bolt safety, and a simplified, serviceable layout that mirrors the original firearm’s ergonomics. The lightweight skeleton stock keeps the package compact and maneuverable for CQB and vehicle-based scenarios while preserving the balance and cheek weld needed for effective aiming.

Compatibility and tunability

The hop-up is Tokyo Marui-spec, ensuring broad compatibility with widely available TM-style replacement parts and upgrades. That makes tuning, repairs, and accuracy upgrades straightforward for techs and operators who like to customize performance.

Who this is for

• MilSim and historical reenactors seeking a visually accurate, functional STEN replica.

• Collectors who value authentic markings and period-correct construction.

• CQB and skirmish players who want a compact, reliable gas blowback SMG with authentic handling.

• Technicians and tinkerers who appreciate TM-spec compatibility and a field-strippable platform.
