Built on a proven V2 gearbox platform, it offers straightforward installation into compatible receivers and delivers consistent chronograph figures around 345fps on 0.20g ammunition.

- Multi-position sliding stock with 1913/20mm Picatinny interface for customisation

Real-World Use Cases
This housing assembly suits a range of airsoft disciplines. Skirmishers benefit from the compact form factor, reliable V2 gearbox platform, and straightforward upgrade path. Milsim players appreciate the M-LOK and Picatinny compatibility for loadout customisation. Builders who already own compatible receivers can integrate this housing to create a fresh or upgraded replica without sourcing individual components. The 345fps output sits comfortably within most UK site velocity limits, and the multi-position stock adapts to different body armour and playing styles.

Compatibility & Upgrades
The V2 gearbox platform is one of the most supported in the airsoft industry. High-torque motors, upgraded springs, and reinforced internals are readily available from specialist retailers. The 20mm rail ecosystem is mature; you’ll find no shortage of compact red dots, magnified optics, and tactical accessories. Magazine compatibility is limited to King Arms MPX-K Sportline AEG mags, so verify your supply before committing. The flared magazine well aids faster changes in the field. Hop-up tuning is intuitive, and the dust-cover access point means you can fine-tune consistency without field-stripping the upper.
UK Legal & Site Notes
This replica is a fully assembled, two-tone (or RIF-compliant) airsoft electric gun suitable for use at UK airsoft sites. At approximately 345fps, it falls within the velocity limits enforced by most venues (typically up to 500fps for AEGs). As always, verify your local site’s chrono limits and magazine capacity rules before attending. The UK Airsoft Skirmish Association (UKARA) membership is recommended if you intend to purchase RIF replicas regularly. This housing requires a compatible receiver to function; purchase as part of a complete build or retrofit into an existing platform.
