Electric Airsoft Rifles use batteries as their power source, they're usually fully automatic, and they shoot very fast. If you are looking for continuous fire fun, this is the type of Airsoft Gun for you - just hold down the trigger and watch those BBs stream out, one after the other, in a straight, swift line - which means fun and entertainment, plain and simple. This Electric Airsoft Rifle doesn't require any pumping just simply point and shoot. This is a high end electric 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.
