Full description


This Airsoft Gun is powered by a Battery in the stock, and comes packaged with the awesome Falcon Fire Control System that allows you to set multiple fire modes from one to five round burst, as well as a Binary Fire mode which fires when the trigger is pulled and again when it is released, for rapid follow up shots to make sure you hit your target.

If you're looking for an AEG with some truly unique features you've come to the right place: the replica features Double Eagles latest creation, the FALCON EFCS fire control system. Usually only seen in custom builds and high end AEG this feature is a welcome inclusion, allowing for 1-5 round bust mode, a Binary fire mode, as well as various gun and battery protection features to boot. The 1-5 round burst mode and Binary fire settings can also be set at the same time, with Binary fire being used in semi-auto mode, and 1-5 round burst replacing the full auto mode. The fire control system is designed to be used with 7.4v Li-Po and 11.1v Li-Po and prevents the replica from firing when it detects a current draw spike, or if the battery voltage is too low. The EFCS fire system is configurable using simple trigger pulls and requires no external tools, special adaptors or a PC to function. For more information please see the Special Instructions Section.

The M904A is partially ambidextrous, with a Fire Selector on both sides to make it comfortable for Left and Right Handed Players. The fire select is even raised to make it easier to select your fire mode even when wearing gloves. Your Battery should be installed in the stock, which is removed by pulling down on the Stock Adjustment Tabs and pulling it off the Buffer Tube. A 7.4v LiPo Stick is ideal for the space you have to hand. The Stock features QD Sling Sockets for the installation of Quick Release Sling Loops.

If you're looking to modify the furniture on the gun you have plenty of options, with a full top length 20mm RIS / RAS rail for attaching red dots, holographic, and even large sight and scope set ups, and an MLOK hand-guard for attaching modular components. If the stock of the replica isn't to taste it can be removed, as well as the front flash hider for replacing with suppressors and tracer units. A 14mm CCW Thread can be found underneath.

In the box you are supplied with the replica, a 300rnd High Capacity wheel wound magazine, and instructions, as well as a battery adaptor to allow deans batteries to be used, a magazine winding key and replacement deans connector should you want to re-wire the replica straight to deans.

This AEG is great for those Airsoft Skirmishers who are looking for a high end gun, at a mid-range price. With plenty of space for external upgrades and an electronic control system in place this replica has features which will make the mouths water of even the most seasoned Airsoft Skirmishers.

FALCON EFCS Protection Feature

Gearbox Protection

When the current is too high or abnormal the power supply on the EFCS will disconnect to protect the motor and battery, and the motor will vibrate three times.

If the voltage of the battery is too high the EFCS power supply will automatically disconnect and the motor will vibrate two times.

Battery Protection

The FALCON is compatible with 7.4v and 11.1v LiPo battery only, with an operating voltage between 6-13v. If the voltage is too low or too high the power supply will be cut. 

When using an 11.1v LiPo the low voltage protection system will notify the user via 5 vibrations, indicating the batteries voltage is too low to be used.
