Presentation by Tanie Militaria of the Amoeba M4 Mutant AMM9 AEG that is available in Dark Earth and Black colours at their store... "The series of the latest replicas by Amoeba Airsoft is based on the well-known design of AR assault rifles, however, these replicas have been appropriately modified and enriched with many design details and interesting technical solutions, such as the full modularity of the fronts and barrel sets, making the mutant a very universal replica.

The body of the replica was made of reinforced nylon . The quality of the materials used makes it hard to recognize at first glance that it is plastic and not metal. There are effective-looking markings on the body, incl. model, caliber, and the Amoeba Airsoft logo. Metal was used for the production of a modular front grip, outer barrel, silencer, stock guide and small parts. The pistol grip is properly profiled, covered with a rough, non-slip texture , which increases the grip and comfort. The magazine release button  has been enlarged to make it easier to use.

The replica is equipped with a telescopic, adjustable stock that allows you to adjust the length to the build and preferences of the shooter. The battery can fit inside the stock and the guide. Access to the hop-up system adjustment is obtained as standard for this type of construction - by pulling the charging handle back and revealing the shell ejector window.

The mutant has a modular front grip unit, which allows the replica to be fully adapted to the individual needs of the user. Depending on the needs, one replica can serve many different purposes. Replacing the front assembly with the barrel and the chamber has never been so easy!

Amoeba Airsoft replicas have the option of quick spring replacement without the need to disassemble the gearbox skeleton. The heart of the replica is a reinforced, slightly modified v.2 gearbox with an integrated EFCS module - Electronic Firing Control System . It controls the operation of the trigger assembly, causing smooth operation and shortens the engine response time to pressing the trigger. The standard contact block has been replaced by an electronic system. EFCS also has a  built-in MOSFET chip .

EFCS significantly  increases the life of the mechanism , and thus the entire replica, and allows the use of high voltage batteries, including LiPo. After purchasing an external, dedicated EFCS programmer , we will be able to set the order of the fire modes, as well as the burst mode (3-ball series).

The magazine attached to the replica is made of mid-cap material with a capacity of 140 BBs. The magazine is covered with a rough, non-slip texture, it also has a foldable pull-mag handle."
