Here is the take of Evike.com on the EMG Sharps Bros AEG series that is available at their store... "An Exclusive collaboration project between EMG and Sharps Bros. Firearm Design, the Hellbreaker II Airsoft receiver accurately depicts the fine detail and craftsmanship of the real AR15 firearms receiver. The stunning and fierce details of the Hellbreaker II really sets this apart from your average rifle and brings a whole new meaning to personal weapons customization. These fully featured rifles are made not only to look and feel amazing, but also to perform right out of the box."
