Matt reviews the Echo1 AR57 in this new episode of Evike.com's The Gun Corner... "The Echo1 AR57 AEG utilizes a modified Ver.2 Gearbox with 8mm bearings and a proprietary hopup design that provides a great level of adjustment and accuracy. The full metal rail system up front provides a stable platform for tactical accessories and the tops rails are great for optics and the included flip-up sights. The gun is wired to the stock so any 9.6v Crane style / butterfly type battery will fit perfectly. All in all the Echo1 AR57 is an extremely solid, and very unique twist on a classic design.
