      The Double Eagle M904G Fire Control System Edition (Tan) is a fantastic AEG! Its lightweight 2kg nylon body ensures easy handling, ideal for CQB. The Falcon MOSFET offers programmable burst modes and crisp trigger response. Accuracy is solid up to 35m, though iron sights are subpar—get a red dot!

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





The M904G is a budget-friendly AR15 AEG replica manufactured by the renowned company Double Eagle, a brand appreciated for years by airsoft enthusiasts worldwide. These carbines are known not only for their affordable price but also for their solid construction and attractive features, making them a popular choice among beginners as well as players seeking a replica for training or recreational skirmishes.

Lightweight and Durable Construction

One of the standout features of the M904 replicas is their low weight of approximately 2 kg. Thanks to the use of reinforced nylon instead of more expensive materials like metal, these replicas are considerably lighter than many other models on the market. Although nylon reduces production costs, it does NOT negatively affect durability — the material is strong enough to withstand intensive use, while also providing comfort during prolonged gameplay. This makes the M904 an excellent option for those who want a dependable replica without investing in costly full-metal models.

Comfortable Handling

The AR-15 replica offers several ergonomic improvements. One of the most important enhancements is the ambidextrous fire selector, allowing comfortable and fast operation for both right- and left-handed players. Additionally, the replicas are equipped with an enlarged magazine release, improving reload speed — especially in high-pressure situations. Another benefit is the adjustable stock length, allowing players to tailor the replica to their preferences. The magazine well was designed for quick and secure magazine insertion, further improving handling.

Reliable Gearbox Mechanism

Inside the M904 replica is a key strength of this model: the Gearbox v2, one of the most commonly used and reliable gearbox types in airsoft. It offers excellent dependability and is easy to service or upgrade. The Gearbox v2 includes a Quick Spring Change system, making it easy to adjust replica power to field limits or game requirements. Additionally, M4 carbines are equipped with a rotary hop-up chamber for precise BB trajectory adjustment. The steel gears and 8 mm bearings provide improved durability and smoother operation.

Precise Fire Control

Another major advantage of the M904 series is 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
This gives players greater control over fire behavior, especially useful in situations requiring fast and precise reactions.

WARNING! Set the selector to SAFE before connecting the battery to activate the system.

WARNING! Mode programming is shown in the following video clip.

Overload Protection

User safety was also taken into account. The M904 replica is equipped with an overload protection system that protects the motor and battery from damage caused by excessive current draw. This feature increases the replica's lifespan and ensures longer, more reliable operation, even under intense use.

The set includes:

  • M4 AEG replica
  • 300-round magazine
  • folding iron sights
  • T-connector to Tamiya adapter

Recommended compatible products:

Each replica undergoes a zero inspection. It is tested and chronographed using an XCORTECH X3200.
