Maruyama MP-IX / MP9 DX Gas Blowback with Silencer

The Maruyama MP-IX / MP9 DX Gas Blowback Submachine Gun is an absolute game-changer for gas blowback enthusiasts and CQB players. Painstakingly engineered to replicate modern, Swiss-designed tactical submachine guns, Maruyama has packed this compact frame with robust, reliable internals that provide consistent performance without the excessive bulk or weight of traditional gas blowback rifles.

Premium Construction & Quick-Detach Silencer The exterior chassis is molded from high-impact, rugged polymer that resists heavy field scratches while remaining highly lightweight and maneuverable. Up front, a heavy-duty steel outer barrel is fitted with a specialized tri-lug quick-detach (QD) mounting system. This allows you to attach or remove the included short BT-style mock silencer in seconds with a simple twist-and-push motion. The silencer is internally threaded (14mm CCW), making it incredibly easy to house your favorite compact tracer unit inside for night games or indoor CQB skirmishes.

Upgraded Controls and Heavy-Duty Steel Internals Unlike older generations of this platform that relied on cumbersome cross-bolt safety buttons, the MP-IX utilizes a highly ergonomic, modern HK-style ambidextrous fire selector switch. This allows the shooter to flip seamlessly between Safe, Semi-Automatic, and Full-Automatic modes with either hand. To ensure long-term mechanical reliability under the stress of rapid full-auto fire, Maruyama has reinforced critical wear points with steel. The internal hammer set, sear assembly, and the base of the loading nozzle are all made of steel, giving you unmatched component longevity out of the box.

Snappy Gas Efficiency & Advanced Feeding The MP-IX is powered by a lightweight, straight 45-round gas magazine constructed from a translucent smoke polymer. This transparent shell features dummy bullet details for an immersive look while allowing you to monitor your remaining BB count at a glance mid-game. Thanks to a lightweight bolt carrier assembly, the cyclic rate of fire is exceptionally fast and crisp, paired with a reliable adjustable hop-up assembly that ensures a flat, accurate trajectory.

Key Technical Features:

• Included QD Silencer: Quick-detach tactical mock suppressor with 14mm CCW internal threading for tracer setups.

• Steel Trigger Components: Factory-installed steel hammer and sear assembly for heavy-duty durability.

• HK-Style Fire Selector: Upgraded ambidextrous fire controls replace old cross-bolt safety designs.

• Translucent 45rd Magazine: Allows real-time ammunition tracking; shared with the Maruyama SCW-9/SPC-9 series.

• Integrated Picatinny Rails: Top and right-side 20mm rails for mounting red dot sights, torches, or lasers.

Field Performance The Maruyama MP9 DX operates within a snappy 310–350 FPS range depending on gas type and ambient temperature, making it fully site-legal for indoor CQB and outdoor fields alike. For optimum gas seal performance and rapid blowback response, we recommend operating this replica with high-quality Green Gas paired with 0.25g or 0.28g polished BBs.
