6mmProShop Custom Airsoft AEG Sub-Machine Gun – Swordfish-A5 (400 FPS)

The 6mmProShop Custom Swordfish-A5 Airsoft AEG Sub-Machine Gun is a purpose-built CQB powerhouse designed for players who demand compact size, aggressive styling, and reliable performance straight out of the box. Based on the proven CYMA CM041 platform, this custom build combines a reinforced gearbox, full-metal externals, and a futuristic Swordfish rail system to create an AEG that stands out both visually and functionally on the field.

With an FPS range of 380–400, the Swordfish-A5 delivers competitive performance while maintaining excellent control in tight environments, making it an ideal primary for indoor arenas or a compact secondary for outdoor roles.

Full-Metal Construction with Aggressive Styling

The Swordfish-A5 features a full metal upper receiver paired with a full metal Swordfish upper rail system, giving the gun a solid, premium feel and enhanced durability. The front end comes pre-installed with an aggressive muzzle device and a flat-top, one-piece top rail, creating a clean, modern profile that looks as intimidating as it performs.

This custom Swordfish configuration gives the AEG a futuristic and tactical aesthetic, separating it from standard MP5-style builds while maintaining compatibility with proven internal systems. The metal construction also improves rigidity, helping the rifle withstand the demands of fast-paced CQB gameplay.

Ultimate Compact CQB Platform

Designed as the ultimate compact CQB weapon, the Swordfish-A5 features a folding stock that allows the rifle to be quickly shortened for room clearing, tight corners, and close-quarters movement. When folded, the compact footprint makes it extremely maneuverable; when extended, the stock provides added stability for controlled bursts and precise shots.

An integrated rear sling loop allows for easy single-point sling attachment, perfect for fast transitions or as a backup weapon for sniper and support loadouts.

Proven CYMA Gearbox Performance

At the heart of the Swordfish-A5 is the highest specification CYMA CM041K LiPo-ready gearbox, built around a Tokyo Marui-spec Version 2 design. This reinforced full-metal gearbox is known for its durability, consistent cycling, and excellent upgrade compatibility.

Because it follows the Version 2 standard, the gearbox is fully compatible with a wide selection of aftermarket upgrade parts, making future tuning or performance enhancements simple and cost-effective. Whether left stock or upgraded over time, this platform ensures you won’t be outgunned in performance.

Functional Controls & Accessory Support

The Swordfish-A5 includes a front RIS system with removable rail covers and a vertical grip, allowing players to customize their grip style and accessory setup. The flat-top rail provides ample space for optics such as red dots or holographic sights, perfect for rapid target acquisition in CQB environments.
