The WG Revolver series are apart from most traditional Airsoft revolvers when it comes to constructions, durability and performance. The entire frame and the bull barrel on this revolver is constructed of metal, detailed design and finished to perfection. The full metal constructed wheel flips out to the left for shell loading simulating maximum realism on an Airsoft revolver. The power source (12g) Co2 is hidden inside the ergonomic pistol grip.
