The A&K M4CQB STW delivers professional-grade performance built on proven Systema PTW engineering. This AEG features a reinforced internal design with integrated MOSFET system, crisp trigger response, and quick-swap cylinder capability for FPS customization. The 120-round magazine includes automatic cutoff when depleted, while the full metal construction—receiver, stock tube, and barrel—ensures durability and realistic weight. Fully adjustable hopup and 400+ FPS output make this an ideal choice for serious airsoft operators seeking reliable, field-tested performance.
