Product description

Mutant AMM13 airsoft rifle

The latest airsoft rifle series by Amoeba Airsoft is based on the well-known design of AR assault rifles; however, these airsoft rifles have been appropriately modified and enriched with many design details and interesting technical solutions, such as full modularity of the fronts and barrel sets, making the Mutant a very universal airsoft rifle.

The body of the airsoft rifle was made of reinforced nylon. The quality of the materials used makes it hard to recognize at first glance that they are plastic, not metal. The body features eye-catching markings, including: model, caliber, and the Amoeba Airsoft logo. Metal was used for the production of the 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 airsoft rifle is equipped with a telescopic, adjustable stock that allows the length to be adjusted to the body type and preferences of the shooter. The battery fits inside the stock and the guide. Access to the hop-up system adjustment is obtained in a standard way for this type of construction - by pulling the cocking handle back and revealing the shell ejector port.

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 requirements, one airsoft rifle can serve many different purposes. Replacing the front assembly with the barrel and the chamber has never been so easy!

Amoeba Airsoft rifles have the option of quick spring replacement, without the need to disassemble the gearbox skeleton. The heart of the airsoft rifle is a reinforced, slightly modified v.2 gearbox with an integrated EFCS - Electronic Firing Control System module. It controls the work of the trigger assembly, providing smooth action and decreasing the reaction time of the motor, after pressing the trigger. The standard contact block has been replaced by an electronic system. EFCS also has a built-in MOSFET unit.

EFCS significantly increases the lifespan of the mechanism, and thus the entire airsoft rifle and allows the use of high voltage batteries, including LiPo. Purchasing an external, dedicated EFCS programmer allows the user to set the order of fire modes, as well as the short-burst mode (3-pellet bursts).

The magazine attached to the airsoft rifle is a plastic, mid-cap clip with a capacity of 140 pellets. The magazine is covered with a rough, non-slip texture, featuring a foldable pull-mag handle.

The set does not include a battery or a charger.

The set includes:

Velocity [FPS]

It is the spped of bb, while its leaving the innerbarrel of replica. This speed is measured in FPS (Feet Per Second).

1 FPS = 0,3 m/s

1 J = 99 m/s

1 J = 326,7 FPS

Gearbox version

Indications v2, v3, v6 does not mean the level of advance, but only shape of gearbox skeleton which was used and selected by the manufacturer depending on the capabilities of the body of the replica. For example, a models of the M4/M16 family, MP5, have a v2 gearbox, while the AK family have gearbox v3.

Hop-Up system is used for overclocking bb during the shot (putting it in rotation), through which, it extends its flight path. Acting laws of physics make that bb lift up, while the gravitational force take it down. Appropriate adjustment of Hop-Up, will compensate for these two factors, which result in long and straight flight for longer distance and be greater focus shot (to improve accuracy).

Blow Back

Blow back is a simulation system of the cocking lever - it imitates the work of it as the equivalent sharp. This system raises the realism and adds a lot more experience during shooting.

Battery included

NiCd rechargeable battery is characterized by high efficiency current-carrying capacity, but there are disruptive effect on memory. Should be unloaded and loaded in the full cycle, ie, it is recommended to fully discharge, and after unloading must charge the battery immediately without leaving it for a long time in a discharged state.
NiMH batteries have a higher self-discharge over time and shorten the life - on the other hand, they earn about 30% more capacity.
