Electric Airsoft Rifles use batteries as their power source and they shoot very fast. Some Electric Airsoft Rifles come with semi-automatic fire. That means that when you pull the trigger only 1 BB will come out at a time. Other Electric Airsoft Rifles come with full-automatic fire. This means that when you pull the trigger multiple BBs will come out at a time. The longer you hold the trigger down the more BBs come out. Check the description above to see which kind of gun this is and if it is right for you. Electric Airsoft Rifles don't require any pumping or cocking, 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 proper working order. Using anything else as ammunition for this gun will void the warranty and may cause it to jam. Also, to keep your Electric Airsoft Gun working properly, do not fire the gun when there are no BBs in it as it may cause damage to your gun. You must be 18 years of age or older to purchase this Airsoft gun.
