Description

This Airsoft Electric Gun is based on the M4/AR Platform which will make it very familiar to anyone who has used the platform before. Featuring a lightweight but incredibly tough construction that is mainly reinforced Polymer, this Airsoft Gun is perfect for those who like to get up in the enemy's personal space.

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 burst mode, a binary trigger, as well as various gun and battery protection features to boot. The 1-5 round burst mode and bump fire settings can also be set at the same time, with binary 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. Please note that an 11.1v LiPo is only recommended by the manufacturer on the grounds that the replica is firing above 390FPS. As your purchase will be ~340FPS out of the box, please avoid the use of an 11.1v Battery. The EFCS fire system is configurable using simple trigger pulls and requires no external tools, special adapters or a PC to function. For more information please see the Special Instructions Section.

The gun features a typical AR platform layout, with an Ambidextrous Safe/Semi/Auto Fire Selector (which can be programmed without the need for tools), but notably a Flat Blade Trigger and Ergonomic Charging Handle. Not only do these parts look awesome, but they make the handling and operation of the rifle much easier. The Battery is stored in the Stock, where you will find a Deans Connector (a Deans to Mini Tamiya Converter Lead is supplied in the box). Simply open the Stock up fully and remove the back section to access the Battery Compartment. The Gun also features a Rotary HOP Unit which is accessible behind the Mock Bolt / Dust Cover. Simply pull back on the Charging Handle to expose it and make adjustments. This will apply backspin to your BBs and help achieve a better flight path, when given the right settings for the BB weight and location. The Suppressor in the pictures is included with the Rifle, and comes installed out of the box. This can be removed to make use on another Muzzle Device by simply unscrewing it. Underneath you will find a 14mm CCW Thread that is recessed inside the Handguard. The Gun also reportedly features a Quick Change Spring System, which is helpful for those who play at multiple sites, each with different power limits. Or maybe you want to float between Assault Rifle and DMR rules, and like to have the option of both without disassembling the Gearbox.

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 handguard for attaching modular components. A solid sling loop can be found underneath the Stock, for making use of a One Point Sling Setup, or a Two/Three Point if you were to add another Sling Loop at the front of the Rifle.

Included in the box is a 300rnd High Capacity Magazine, which is filled with BBs from the top via the Fill Window, and then wound at the bottom of the Mag to start feeding BBs into the gun. If you're looking for an incredibly smart Airsoft Gun with some unique external furniture as well as a solid Alloy body, then you can't go wrong with the Double Eagle M904L Fire Control System Edition.

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 twice.

Battery Protection

The FALCON EFCS has an operating voltage between 6-13v. If the voltage is too low or too high the power supply will be cut. If the voltage of your battery is too low, the FALCON will notify the user via 5 vibrations, then cut the power to protect your battery.

The externals of the replica are metal where they would be on the real world gun. This includes things like the outer barrel, handguard, and receiver. If a real world gun has polymer parts then the gun will still be marked as full metal externals, examples of this would be an M4, where the Stock and Pistol grip are always made from Polymer.
