This is a CO2 powered Airsoft Pistol which means that it uses CO2 Gas as a propellant. It shoots hard and fast and is extremely lifelike. One feature many CO2 Airsoft Guns have is blowback, meaning that as the BB is propelled forward the slide thrusts backward mimicking the kick of a real gun! This CO2 Airsoft Pistol doesn't require any pumping just simply point and shoot. This is a high end CO2 Airsoft gun. Please only use .20 gram high quality BBs with this item in order to keep it in working order. Using anything else as ammunition for this gun will void the warranty and may cause it to jam. You must be 18 years of age or older to purchase this Airsoft gun. You will need to purchase CO2 for this gun separately.
