      The M904H Falcon feels great and has a very solid build quality. The design looks clean, and the rifle is comfortable to use during long airsoft games. The ETU system works well and gives a nice response when shooting. The rifle feels reliable, accurate, and easy to handle. Overall, it is a great airsoft rifle with good performance, and I would recommend it to other players.

      Based on my experience over three game days, I can confidently say that it’s one of the best value for money airsoft replicas I’ve used so far. From the moment I first picked it up, it was obvious that this is not your average entry-level AEG. The external build quality is surprisingly impressive, the polymer body feels solid, with no creaking or rattling, and all parts fit together nicely. The weight is also very well balanced, making it comfortable to use even during longer games while still feeling sturdy and premium. The Falcon 3.0 ETU system is easily one of the biggest highlights for me. Trigger response is extremely fast, especially when paired with an 11.1V LiPo battery. The semi-auto response feels almost instant, making it very satisfying to use during gameplay. Features like burst mode and precocking are a huge bonus at this price point. Throughout all three games, the replica performed consistently with no cycle issues or electronic problems. Internally, the quality was also a very pleasant surprise. The gearbox comes well assembled from the factory, the shimming feels properly done, lubrication is decent, and the air seal is stable, which results in very consistent performance. You can tell that Double Eagle actually put effort into the internals of this series instead of only focusing on the external looks. The only real weak point I found was the stock hop-up rubber. In my opinion, this is something worth replacing fairly early if you want to get the most out of the platform. I replaced mine with a Maple Leaf hop-up rubber, and that turned it into a perfect combination. Range, accuracy, and BB flight consistency all improved noticeably, and the rifle became much more predictable shot after shot.
      If I really had to mention one small negative, it would be the stock, which has a tiny bit of wobble. However, this is a very minor issue, and it doesn't even stand out while playing, especially since it's really easy to fix, so it was never a problem for me.

      This rifle looks amazing, feels good quality. In short, it worth every dollar euro or pln that you will pay
      You not gonna be dissapointed
      Very good precision light, acurate shots and most importantly it has many programs, like auto, manuala, semi auto, pre-cock, on this mode you can hear shooting sound closer like real gun. It is not that loud bud more like it.

      Great value for the money. Shoots very nicely and accurate. You can fit a very big battery in the stock. Magazine has a little wobble but not much. Would recommend to anyone who is looking to buy their first replica, this is quite the bang for the buck.

      This specific line of rifles is probably one of the best all around choices if you were to get your first ever gun. Comes with a Tamiya to T-Plug adaptor, but honestly not the best thing in the world as there's not enough space for the stock to fully collapse with the adaptor installed, for that case they also included a T-Plug head if you want to convert your Tamiya battery to a T-Plug one, but it requires certain tools which wouldn't really lie around if you're a regular dude. The included hi-cap magazine has a little wobble, it doesn't matter as much, but ever since I've started using BattleAxe mid-cap magazines, the wobble itself is almost completely gone. Performance wise this gun is great straight out of the box.

      Best gun for the money. It wasn't needed but I upgraded it with ML inner barrel, ML hop bucking, RetroArms. I would advise you to get the full metal version, it's worth it! Anyways the 904h is top notch, you can make it dmr or cqb it doesn't matter. Almost anything on the market fits out of the box to the gun.

      the only thing is the space between the barrel and under barrel is so small impossible to get anything attached

      Perfect gun for this price. Easy to handle, accurate, lightweight. Falcon System works properly, it was easy to setup and fairly variable.
      The only negative issue is the battery. The recommend battery doesnt fit perfectly and we cannot pull back the stock completely when the battery is in.

      Estou satisfeito. Bastante silenciosa e rápida.

      Ter em atenção que o sistema M-Lok não permite ser montado na zona do silenciador assim como o punho vertical.

      I am satisfied. Quite silent and fast.

      Please note that the M-Lok system cannot be mounted in the silencer area as well as the vertical handle.

Double Eagle M904 with Falcon Fire Control System — Check out the other products in the series





The M904 series consists of economical, modern AEG replicas created by Double Eagle for players seeking lightweight, ergonomic, and functional carbines for dynamic ASG gameplay. The construction made of durable, reinforced nylon significantly reduces the weight (approx. 2 kg), improving comfort during long matches and making the replica easier to maneuver.

The carbine features several improvements such as ambidextrous controls, an enlarged magazine release button, an additional “star-shaped" auxiliary release, and an adjustable handguard. These solutions increase speed and intuitive handling, especially during frequent magazine changes.

Inside, the replica houses a V2 gearbox with a Quick Spring Change system, steel gears mounted on 8 mm bearings, and a rotary hop-up chamber that allows precise adjustment of BB trajectory.

The M904 series is also equipped with the advanced electronic control system Falcon 3.0.

Falcon EFCU 3.0 offers 4 selectable modes:

  • Mode 1: 3-round burst, 6-round burst, AUG mode
  • Mode 2: trigger sensitivity adjustment
  • Mode 3: 2-shot / binary mode
  • Mode 4: precocking
WARNING! Before connecting the battery, set the fire selector to SAFE to activate the system.
WARNING! Mode programming is explained in the video material.

Included in the set:
  • AR-15 replica
  • Hi-Cap 300 BB magazine
  • folding sights
  • T-connector › Tamiya adapter
