Description
Maruyama MP-IX / MP9 DX Gas Blowback SMG with Silencer
The Maruyama MP-IX is a gas blowback replica of the compact MP9 sub-machine gun, and this DX version comes with a silencer. It is small enough to handle like a large pistol, yet with its folding stock and foregrip it can be shouldered and controlled like a carbine, which makes it a superb choice for CQB.
Maruyama is a long-established Japanese airsoft manufacturer. The MP9 design is famous for packing a lot of capability into a very small package, and in gas blowback form it gives real recoil and a fast, punchy rate of fire. It suits CQB players, PDW fans and anyone who wants a compact primary or a powerful secondary.
Build
A retailer listing describes construction from polymer, steel and aluminium alloy, with an overall length of about 297mm and a weight of about 1280g, or about 1680g with the silencer fitted. The steel outer barrel has a three-lug MP9-style QD mount for the silencer.
Picatinny rails on the top and sides give space for a red dot, torch or laser, and the folding stock and foregrip help you keep the gun steady and controlled, especially on full auto.
Performance
This is a green gas blowback SMG, so the bolt cycles on every shot for realistic recoil. The listing gives a 45-round magazine, a 120mm inner barrel and an adjustable hop-up, with safe, semi and full-auto fire.
Gas performance depends on temperature, so keep your magazines warm in cold weather and rotate between them through the day. Use good quality green gas and seamless 6mm BBs for the best results.
The silencer
The DX package includes a short silencer, described as BT style, which fits the three-lug mount. The listing describes it as having a mounting point for a tracer unit, so it can be set up for night games. It adds to the look of the gun and helps balance it in the hands.

Compatibility
Use Maruyama MP-IX gas magazines; MP9 magazines from other makers may not fit, so check before buying spares. The three-lug mount takes the included silencer, and the listing describes a tracer mounting point on the silencer. Red dots, torches and lasers fit the Picatinny rails. Use green gas made for airsoft, never lighter fluid or butane.
Care and maintenance
Store the SMG with the magazine removed and keep a little gas in each magazine so the seals stay supple. Put a drop of silicone oil on the magazine valves and seals now and then, and lightly lubricate the bolt rails; never use petroleum-based oils.
Clean the inner barrel with a rod and lightly oiled patch if accuracy drops. Check the silencer is locked securely on the mount before each game, wipe the gun down after damp games, and store it somewhere cool and dry.
Who is it for?
The Maruyama MP-IX DX suits CQB players and PDW fans who want a compact, hard-hitting gas blowback SMG with real recoil, and players looking for a powerful secondary that can double as a primary indoors.
Please note: Gas and BBs are not included. Always wear suitable eye and face protection, and check the power limits and full-auto rules at your site before play.
