It's the turn of Airsoft GI to explain what makes the Echo1 AR57 AEG unique... "If you have ever wanted to own a gun that not to many of your friends have, then maybe you should consider picking up the AR57 by Echo 1. Based off the real steel firearm, the AR57 was designed to give AR shooters a solid base to shoot off of while still using the quality FN 57 round. Plus, this gun is fully licensed through Echo 1, so the gun is really a great gun to have. Be sure to check it out on our website."
