Umarex Colt SAA Revolver CO2 (6mm) – Silver
The Single Action Army of choice when buying a revolver. These are CO2 powered, have no hop-up but are extremely fun to use and much more reliable than most other brands on the market. They are full metal construction with plastic grips concealing the CO2 reservoir. You need to cock the hammer each time to fire these and they come with six metal shells.
