A good look at the G731 CO2 revolver from WinGun in this video review by GM Tatico. The Win Gun Model G731 Airsoft CO2 Revolver is a compact, and heavyweight nickel-plated revolver featuring a full metal frame and cylinder, realistic operation with included heavyweight brass shells (and spares available), and a powerful 400 FPS output. It's designed for ease of use with an easy-access CO2 compartment, an ergonomic diamond-textured grip, fixed sights, and an on-frame safety.
