Mach Sakai reviews the Ares Amoeba AR308S HPA, which uses a solenoid valve, going over its measurements, weight, and magazine capacity. He points out the features such as its 3-port flash hider, metal upper and lower receivers, adjustable front and rear sights, M-LOK handguard, ambidextrous magazine release, custom trigger guard and flat trigger, and adjustable stock.

Furthermore, he assesses the gun's performance by examining its firing sound and trigger pull, followed by tests in speed shooting and bullseye shooting scenarios, and evaluates the hop-up effectiveness with both 0.2g and 0.25g BBs. Ultimately, he concludes that the airsoft gun is an excellent choice for individuals who value minimal recoil and sound output.
