ARES has continued with their innovation of AEGs with their latest generation of their M4 Amoeba series AEG. The Amoeba M4 features custom furniture and receiver styling from top to bottom. Starting at the rear, the crane style stock allows you to install a variety of batteries namely the butterfly crane stock style battery. Moving onward you will find ARES's unique pistol grip that features a unique and comfortable profile along with grip texture and a vented base plate to reduce motor overheat. The upper and lower receiver of the Amoeba M4 also features a unique design by adding curvature and further detail, giving it a more futuristic and high end look than the standard M4 receiver. An enlarged magazine catch and improved straight trigger rounds out the lower receiver to not only increase ergonomics but aesthetics as well. The AM-013 assault rifle employs a new foregrip design to adapt modern rifle shooting method as well as light weight modular rail system which allows a wide array of optional accessories such as lights, and lasers.
The Improved 3rd generation Electronic Firing Control System (EFCS) can withstand around 30A firing current and provide better piston cycle position which ensures more steady firing speed and prolongs spring longevity.
Internally, the AMOEBA comes straight from the box with high quality internals as well as the gearbox being compatible with the aftermarket ARES fire control unit (not included) for programmable burst fire as well.The AMOEBA uses ARES's Electric Fire Control System so you can control your AMOEBA to fire in burst, semi ,and of course full auto. Inside, a MOSFET has been installed so each and every single shot is even and consistent with one full rotation of the gears. Internally the AEG also features the high end metal gears and high strength polymer piston parts which are sure to maximize performance and durability. The textured grip houses a high-torque motor that performs beautifully with nearly any style of build, which comes in handy due to the quick-change system. The 6.03mm tight-bore barrel also adds to the AEG's performance.

"This was my first ever Airsoft gun and it’s been 2 years that I’ve had it. Been a GREAT gun and has never gave me issues. There is a website decided to special parts just for this gun that I have on mine. If you are looking for a great starter gun or just a cheaper good gun, this is it. Trigger response is the most beautiful I’ve felt on any gun I’ve owned since!

"This thing is an absolute beast right out of the box. The trigger is phenomenal and the weight and feel of it are top notch. The Airtech battery extender is a must buy for it as the stock battery compartment is very small. Other than that, this machine just runs with an 11.1 in it. Worth every penny.

"Amazing! Shot 390 fps out of the box. (have my own chrono). Added a prometheus purple day 1, took it to my range (210ft to target) and was hitting with .28g bbs 2 out of 3. Tried .32s, .36s, and .40s and adjusting hop a bit with each increase in weight.. Accuracy got better each time, and was still comfortably hopping out to the 210 ft mark. For fun, I had BioShot bbs in .45g weight, and tried them... WOW! Hopped out to 210ft, and fell just past, estimating the range with .45g to be about 220ft or so. I took this to an outdoor field last saturday and had the best airsoft game I've ever had!! Wherever that red dot rested the bb's went. There were over 100 people there, snipers and HPA and polarstars and normal AEGs, and NOT ONE had the range+accuracy that this bad boy has!!

I have midcap k120's, and by the third mag in 10 minutes the handgrip (motor) was getting warm, I knew this from reading previous reviews, and to let others know not to worry and it is normal. Also, I didn't have a single misfeed with k120s (4 different mags) and they all ran great through 8 intermittent hours.

Must haves: Prometheus purple hop (watch YouTube on how to change a hop bucking, it's SIMPLE. In and out of Amoeba in 5 minutes.)

Airtech Battery compartment extender.

Barrel Stabilizer by airtech OR plumbers tape on the outside-end of the inner barrel. It's easy to research this, how and why it is needed. The tip of the inner barrel has too much space between it and the outside barrel, causing a tad wobble and inconsistencies in long range shots. Easy fix.

I have owned many mid-range ($300ish) AEGs from CYMA, Classic Army, the ICS L85A2, Valken, and THIS IS BY FAR THE BEST out of the box.
