Double Eagle M904 M4 with Falcon Fire Control System (Blue – M904G)
The Double Eagle M904G is a compact, Honey Badger-styled member of Double Eagle’s M904 family, fitted with the Falcon Fire Control System and finished in blue. It brings a programmable electronic trigger to a budget-friendly rifle, giving newer players features that used to be found only on much more expensive AEGs.
Double Eagle has built a strong following for affordable, well-specified rifles, and the Fire Control System Edition is one of its most popular ranges. The M904G pairs that electronics package with a light polymer body, an M-LOK hand guard and a sliding PDW-style stock, making it a quick, easy-handling rifle for CQB and woodland alike.
Falcon Fire Control System
The Falcon system is an electronic fire control unit built into the V2, front-wired gearbox. It lets you set full-auto to fire a burst of between one and five rounds, add a bump-fire style trigger mode to semi-auto, and choose from three trigger sensitivity levels. Everything is programmed with trigger pulls, so you do not need a computer or tools, and holding the trigger for five seconds resets it to default.
It also protects the rifle. Gearbox protection cuts the power if the current draw or voltage is abnormal and warns you with a motor vibration, while battery protection works within a 6V to 13V range and gives a low-voltage vibration warning before cutting off, helping to protect your LiPo.
Build and handling
The externals are reinforced nylon polymer with an alloy outer barrel assembly, keeping the weight to around 2kg. A full-length 20mm top rail takes optics, and the M-LOK hand guard has space for grips and lights. Flip-up iron sights are included and can be removed if you fit an optic.
Controls are ambidextrous, including the charging handle, magazine release and fire selector, and there are QD, receiver and stock sling points. The three-position Honey Badger-style sliding stock keeps the rifle compact, and the removable flash hider is secured by a grub screw over a 14mm thread. The rotary hop-up adjuster sits behind the mock bolt plate and is reached by pulling back the mock charging handle.
Getting started
Charge your battery on a proper charger and fit it following the manual. Load a magazine and test-fire at a safe backstop, starting with the hop-up off and bringing it up gradually until shots fly flat. A few minutes of zeroing at the range makes a big difference to your confidence on the field.
Practise magazine changes and battery swaps at home, and get the rifle chronographed at the site before your first game.

Compatibility
The M904G is designed for 7.4V and 11.1V LiPo batteries only, with 11.1V recommended; LiFe and NiMH batteries are not supported. The battery fits in the block where a buffer tube would normally sit. The rifle has a Deans connector and comes with a Deans to Mini Tamiya adaptor. The M-LOK hand guard takes M-LOK accessories, and the 20mm top rail accepts standard optics. Many M4-pattern AEG magazines should fit, but try any spare magazine before a game.
Care and maintenance
Take the battery out after every game and store it away from the rifle, and charge LiPo batteries only on a proper balance charger under supervision. Clean the inner barrel with a cleaning rod and a dry cloth patch every few games, as dirt and broken BB fragments are the main causes of flyers. Stick to good quality seamless BBs of a consistent weight.
Check screws, the flash hider and any mounts before each game day, and store the rifle somewhere dry. Leave the hop-up at a light setting in storage, and if the rifle has an electronic trigger unit, a fully charged battery helps it read the trigger cleanly.
Who is it for?
The M904G suits players who want electronic fire control on a modest budget, especially those who play at CQB or mixed sites where a short, light rifle is an advantage. The programmable burst and trigger settings also make it a fun rifle for experienced players to tune to their own style.
Please note: a battery, charger and BBs are not listed as included. Always wear suitable eye and face protection when using airsoft replicas.
