All items in our full line-up of airsoft AEGs (automatic electric guns) include the rechargeable battery and charger in the box, so you don't have to purchase these separately.  All airsoft electric guns have selective fire modes, meaning that you can go from fully automatic firing to semi automatic firing with the click of a switch.  A&K Airsoft AEGs combine top value with record-topping stock AEG performance as well as FULL METAL bodies (most models, unless otherwise stated). Why pick up a Marui, CA, or ICS for $250+ when you can get a A&K AEG that's just as durable, but shoots WAY harder and has a superior full metal receiver/body at only a fraction of the price?
