SA MP40 RETRO AEG Submachine Gun (X-ASR) – Grey / Brown

Specna Arms MP40 RETRO AEG with X-ASR MOSFET

This professional product description was prepared by the expert team at ANAREUS.cz. All rights to this unique content are reserved by anareus.cz.This authentic MP40 replica from the Specna Arms RETRO series was developed in cooperation with S&T / AGM and faithfully recreates the legendary German World War II firearm. The construction combines a metal receiver (frame, barrel, sights, and magazine well) with polymer furniture for both realism and durability. One of its signature features is the folding metal MP40 stock, allowing the replica to be shortened for transport or use in confined spaces. Another authentic detail is the mechanical fire mode selector, operated by the position of the charging handle—forward for semi-automatic fire and rearward for full-auto. Reliable performance is ensured by the integrated GATE X-ASR MOSFET with a T-Dean connector, which protects the electronics, improves trigger response, provides basic diagnostics, and supports high-performance 11.1V Li-Pol batteries. The replica delivers a muzzle velocity suitable for most public fields and indoor arenas, features an adjustable hop-up chamber, and is an excellent choice for WW2 MilSim, reenactment, and historical firearms enthusiasts.

Frequently Asked Questions (FAQ)

Is it suitable for regular skirmishes or mainly for reenactment?

Both. It delivers enough performance for regular airsoft games, while truly shining during historical events and WW2 MilSim scenarios.

What battery does it use?

It uses batteries with a T-Dean connector. We recommend an 11.1V Li-Pol battery for the best performance and trigger response. The battery is installed above the gearbox under the receiver cover, similarly to AK-style replicas. Avoid overly long batteries so they fit properly (max 120 x 30 mm).

Which magazines are compatible?

Use Specna Arms MP40 / STEN magazines, or magazines designed for the S&T MP40 and AGM MP40 / STEN. SRC MP40 magazines are not compatible because they use a differently shaped magazine cap.
