Specna Arms MP40 RETRO AEG Submachine Gun with X-ASR MOSFET
The Specna Arms MP40 RETRO AEG is a full-size historical airsoft submachine gun designed for WWII reenactors, collectors and players who appreciate authentic military styling. Developed in collaboration with S&T/AGM, the Specna Arms RETRO range combines faithful external reproduction with practical electric internals suitable for regular airsoft gameplay.
With its iconic folding stock, metal construction and unmistakable silhouette, this MP40 airsoft replica captures the appearance of one of the most recognisable submachine guns of the Second World War. Inside, a factory-installed GATE X-ASR MOSFET adds modern electrical protection, improved trigger response and basic diagnostic functionality.
An Iconic WWII MP40 Airsoft Replica
The MP40 was widely used by German military units during the Second World War and became one of the most recognisable submachine guns of the era. Its distinctive shape, under-folding stock and straight magazine have made it a familiar sight in historical films, documentaries and games.
Although the MP40 is often incorrectly referred to as a “Schmeisser”, the design was not created by Hugo Schmeisser. Historical confusion was partly caused by Schmeisser-related markings found on some magazines rather than on the weapon itself.
The Specna Arms MP40 RETRO recreates the defining features of the original platform, making it a strong choice for historical displays, reenactment events and collections of WWII airsoft guns.
Metal and Polymer Construction
The replica uses a combination of metal and durable polymer to reproduce the appearance and handling of the original MP40 while maintaining practical field durability.
Metal components include:
- Folding stock and frame
- Outer barrel
- Front and rear sights
- Magazine well
- Bolt cover
Polymer is used for selected body sections and the pistol grip panels, reflecting the material contrast associated with the historical design.
At approximately 3170 g, the MP40 RETRO has a substantial and realistic feel, making it suitable both as a functional airsoft replica and as a collector’s display piece.
Folding Stock for Compact Handling
The MP40’s characteristic metal stock folds underneath the replica, reducing the overall length from approximately 830 mm to 630 mm. This compact configuration makes the replica easier to transport and improves handling in buildings, trenches and confined CQB environments.
With the stock extended, the replica provides a more stable shoulder position for aimed fire. When folded, it retains the compact profile associated with the original submachine gun.
Semi-Automatic and Full-Automatic Fire
Unlike many standard MP40-style airsoft replicas, this RETRO model offers both semi-automatic and fully automatic fire. The firing mode is selected through the position of the charging handle:
- One charging-handle position enables single-shot fire
- The alternative position enables fully automatic fire
This unusual selector arrangement preserves the clean historical appearance of the replica while giving the player greater control during gameplay.
GATE X-ASR MOSFET
The factory-installed GATE X-ASR MOSFET protects the replica’s electrical components and trigger contacts from excessive wear. It also improves current flow and supports a more responsive trigger cycle.
Integrated indicator LEDs provide basic diagnostic information, helping identify selected electrical faults during maintenance or troubleshooting. This makes the X-ASR a valuable upgrade for a historical AEG that may see regular use on the field.
The replica is fitted with a modern DEANS/T-Plug connector for efficient electrical contact. Battery and charger are not supplied and must be purchased separately from the airsoft batteries and chargers collection.
Special Gearbox and Adjustable Hop-Up
The Specna Arms MP40 RETRO is powered by a dedicated special-version gearbox and delivers a listed muzzle velocity of approximately 400 FPS. Its adjustable hop-up system helps stabilise the BB during flight, improving effective range and shot consistency.
The 265 mm inner barrel provides a practical balance between compact dimensions and outdoor performance. Always check the replica’s actual muzzle energy against local legislation and the limits imposed by your airsoft field.
120-Round Mid-Cap Magazine
The included mid-cap magazine holds up to 120 BBs. Mid-cap operation eliminates the need for winding and reduces the rattling noise associated with high-capacity magazines.
This supports a more immersive style of historical gameplay while still providing enough ammunition for standard skirmishes. A BB speedloader is included for convenient loading.
Ideal for Historical Airsoft and Reenactment
The Specna Arms MP40 RETRO is particularly suitable for:
- German WWII airsoft loadouts
- Historical reenactment events
- Second World War-themed skirmishes
- Collectors of classic military replicas
- Players seeking a metal MP40 AEG
- CQB players who value a folding-stock design
Its combination of iconic styling, substantial construction and modern MOSFET protection makes it equally effective as a field replica, reenactment piece or collector’s display model.
