In this installment of her airsoft hunt, Airi explores the MPX from Stratos, a manufacturer known for internal parts rather than full builds. This specific model is a 9mm version of the popular MCX and comes as a set with a folding minimal stock. Whilst Airi finds the safety selector a bit stiff for her hands, she is pleasantly surprised by how light the gun feels, even with the magazine inserted.

The testing phase reveals a snappy performance, with the gas-powered blowback operating smoothly even when the magazine is cold. Airi takes a moment to appreciate the dimples on the magazine, which she initially thinks are just a thoughtful touch for grip before learning they are a standard feature of the real firearm. The gun's internal steel parts suggest it can handle a fair amount of use, making it a strong contender for her final choice.

The episode takes a slightly clumsy turn during the field strip, as Airi struggles with the stiff pins required to reassemble the unit. She admits that while other models were easier to take apart, this one requires a bit more muscle and knack to put back together. Despite the minor wrestling match with the hardware, she says that its high customizability and reasonable price point keep it high on her list of potential sidekicks.
