You've already watched the reviews of this AEG, and now this is in stock at Airsoft Atlanta... "The new Tin Star USA S2S M4 is a great little CQB AEG. With a full metal body and a 120-day warranty, you can't go wrong with this airsoft gun. Full metal RIS system too! A neat feature is the bolt, once pulled back, it locks back for hop up adjustment. When done adjusting, just press the bolt release (like a real M4). A rock solid airsoft M4 gun! Front and rear sites are quick-flip up/adjustable.  Gun package includes battery and charger to get you up and running quickly.
