The Elite Force Smoke Wagon Silver Gas Revolver CO2 airsoft gun. A metal nickel gun design, with all metal components for added durability. Shells system (extras sold separately) that fit BBs in the chamber. Loads like an old-school 1800's revolver on its side. Hop up is set for use with .25g BB weights. FPS is 325 w/.20g - safe for all CQB fields. This is a solid, heavy, and very realistic revolver. Finally a western style single action army airsoft revolver that's very well made!
