M904 is a series of inexpensive AEG replicas from Double Eagle. One of the main advantages of these carabiners is their weight due to the use of reinforced nylon, instead of metal alloys, that's why are very light (about 2kg) and handy thanks to ambidextrous selector lever and charging handle, extended magazine release and magwell or adjustable stock. Mechanism of Gearbox v2 with a quick spring change system mounted on 8mm steel ball bearings and rotary hopup. In addition, as a standard, these replicas are equipped with a Falcon electronic control system with programmable fire mode (Double Shot on SEMI mode or 1-5 Round Burst on AUTO mode), trigger sensitivity adjustment (3 modes) and motor and battery protection.

NOTE! Set the selector lever to SAFE mode before connecting the battery to boot the system.

NOTE! Programming of modes presented in the movie clip.
