[Set] M924 DMP-9 submachine gun replica ETU Wireless [DE] + Cargador de 130 bbs M924 DMP9 [DE]

Funcionan muy bien y permiten que la Réplica deje de disparar al finalizar las BB,s del cargador. Son resistentes y la relación calidad precio es muy buena.----------------------------------------------------------

I recently picked up the Double Eagle M924 DMP-9, and after getting some trigger time with it, I have some solid impressions. I didn't just run it stock, though — I had the guys from Taiwangun do a few tweaks and upgrades before shipping it out.

Before having it shipped, I opted for the lubrication and reshimming service, which I highly recommend. The gearbox sounds incredibly smooth with no grinding noises right out of the box.

I also had the FPS reduced to 330 FPS to make it field-legal here. To maximize performance and offset any range loss from the lower FPS, I swapped the stock inner barrel and bucking for the Unicorn 180mm Nitroflon Coated 6.03mm precision barrel (which conveniently comes with a 60-degree bucking and a 50-degree spacer).

Pros
Insane Precision: Thanks to the Unicorn barrel and bucking upgrade, this thing is a laser beam. The grouping is tight, and it hops heavier BBs effortlessly despite the shorter 180mm barrel length. If you buy this replica, upgrading the stock bucking is an absolute must, and the precision barrel combo does wonders.

Awesome Overall Platform: It's lightweight but feels extremely sturdy — the polymer they used feels closer to real firearm-grade material rather than cheap plastic.

Electronics: The built-in Kestrel V2 ETU is a massive bonus. Having optical sensors and Bluetooth connectivity in an SMG at this price point gives it an incredibly snappy trigger response, especially on an 11.1v LiPo.

Cons
Wobbly Fire Selector: This is my only real gripe. Out of the box, the fire selector felt a bit loose. I tried tightening it down, but it still has a noticeable wobble to it. I'm honestly not sure if this is a widespread design quirk with every M924 or if I just happened to get a slightly out-of-spec selector switch on my specific unit. It doesn't affect firing, but it's a bit annoying on an otherwise rock-solid gun.
The Magazines: I like them, but these are proprietary magazines, so you'll have to buy them and they will be the only chioice.

The DMP-9 is an absolute blast to play with, especially in close-quarters environments. Getting the factory reshimming and dropping in a precision barrel transforms this from a "good budget SMG" into a primary weapon that can easily punch above its weight class. If you don't mind potentially dealing with a slightly loose fire selector, it is 100% worth the money.

If you are searching for a compact AEG with a folding stock, decent battery compartment and standard V2 gearbox (M4 like internals), choice is surprisingly small. DMP-9 checks all the boxes plus it is lightweight. It is made of a good quality material, definitely not a cheap plastic – almost a firearm level polymer.

Out of the box it has 365 FPS (with 0,2g) and almost 20 RPS on 11,1V. Hop up chamber has no problem with 0,3g BBs.

You need to keep in mind that for a good performance you need to at least change the hop up bucking – otherwise accuracy would be quite poor. It involves removing only 2 pins and a screw, but after this simple tweak you are getting performance of much more expensive replicas in a very small and light package.

I managed to fit a larger battery: Gens Ace 25C 1500mAh 3S1P 11.1V (no modification needed).

Parts breakdown and possible upgrades. First the ones that do not involve breaking the seal and thus loosing warranty
• hop-up bucking – it’s only purpose it to keep this replica’s price low. It comes greased up from the factory and is made of stiff rubber. Just assume you have to replace it on arrival. I found Krytac Orange to give best results with DMP-9. Madbull blue and G&G green are decent, but you won’t be able to set 0 hop-up. I wouldn’t recommend 4Uantum with this replica.
• Outer barrel – it is a quality one, but mine came little loose. Simple tightening of the nut fixes the issue – 19 mm wrench might come in handy, but hand tightening using a latex glove should be enough. If you apply medium (blue) thread glue, problem is fixed permanently.
• Inner barrel – made of brass, good quality, with 5mm well machined window – I find it pretty good and didn’t feel a need to upgrade it. Length is 190 mm, closest upgrade is 187mm PDI battel.
• Folding stock – uses Picatinny rail for attachment. Is rather short, but standard for MPX style SMG. Biggest advantage is that you can lower it, making it comfortable to use even with paintball masks. For customization search for 5KU stocks.
• Hop-up chamber – unfortunately proprietary, but is good enough – rotary, never changed it’s setting on itself. It has 11 steps, but they are plenty enough for 0,30g BBs. Hop up arm fits normal nubs, but it is literally made to fit Krytac orange nub. Stock nub is little too soft.
• Spring – in order to be below 1,15 J / 350 FPS limit, Element M95 spring is the best bet. Be careful with weaker M90 or M85 spring as I’ve met a person who had PME with such a weak spring. I had no issue with M95 and 11,1V. Safest option is stock spring and 1 teeth short stroke, but that most likely voids the warranty. There is “quick” spring change system, but it involves undoing 7 screws plus the spring guide – 2 to 3 min work.

Other parts and advanced upgrades (most likely they void warranty):
• Gearbox shell – typical DE – much stronger than it looks to be. From the first glance it has laughable radiuses, but despite the looks these gearboxes (from my experience) can withstand much more than they were designed to.
• Gears – they are 16:1, pretty standard, but strong. There is a delayer chip installed, but it is not necessary and can be removed.
• Cylinder – quality type 2 steel cylinder. No need to replace, just check for possible burr in the window and smooth it with a file.
• Nozzle – plastic, unsealed, with some wobble. Stock length 21.25 mm. Replacing improves seal. For Krytac Orange houp-up bucking, 21.1 mm nozzle is enough (Maxx or Epes).
• Cylinder head – good enough. Made of plastic, but this is an advantage, since it absorbs shock better and transfers less force to the shell. Seal with cylinder is perfect.
• Piston head – same as with cylinder head – plastic, good enough, perfect seal. It has a bearing. Only gripe is that it is held by a plastic thread.
• Piston – unfortunately only last teeth are metal. Good enough for 1-2 teeth short stroke, but nothing more. Most pistons don’t fit or require modification. Best is Begadi Redux and french Balistik (requires shortening pick-up tooth). Fps softair piston requires heavy modification (shortening all teeth). Slong doesn’t fit and some people can get SHS to fit but it is not a good idea.
• Tappet plate – perfect. Most aftermarket tappet plates would be a downgrade.
• Motor – high torque, but nothing fancy. Does it’s job.

Biggest advantage of DMP-9 is the Kestrel ETU – full one with bluetooth, not basic like with most other replicas. It is fully optical (trigger, selector, cycle detection). I had absolutely no issue with it. Works well with brushless motors and DSG. From usability perspective app works well and replica is password protected. Also there is no account creation or other bloat, so this is also a plus.

Magazines are proprietary, but are cheap, feed till last BB and can handle even very high ROF (40 RPS). They also give the benefit of supporting “Real Gun Mode”, which prevents the replica from firing with an empty magazine.

Advantages:
• One of the best ETUs
• Compact and lightweight
• Possible to use with face masks
• Folding stock
• Fits large 1500 mAh 11,1 V battery
• Compatibility with most v2 aftermarket parts
• Very good performance after replacing just hop-up rubber

Disadvantages:
• Stock hop-up bucking is terrible
• Needs screw/nut tightening to fix barrel wobble

It's a nice compact and light smg. Modern technique internals. The fact that it needs proprietary mags is a bit of a bummer, but they're affordable. Finding a 11.1V lipo battery is a bit of a challenge. Mine came with the barrel a bit offset. Not something that makes the replica unusable, but it's not something you expect from a brand new replica.
