Basically I bought an Echo 1 GAT, but I haven't really used it. It has just been sitting in its shipping box it came with under my bed. I've used it about 5 times, and those were simply test fires. I HAVE NOT brought this to ANY airsoft game yet. The only reason I'm selling it, isn't because I'm dissatisfied, but because I haven't the time to use it. Text or comment if you are interested.
