i just got the echo1 m4a1 and it is great! i got a version 2 somehow and it shoots 385+ fps! the rps isnt too bad either,reaching 10-13 for me with the stock battery. i love this gun! get it from airsoftgi.com,they have great service and are very friendly. the gun is very accurate and i can hit targets out to 70 yards,yes,i did measure it. maximum distance is around 75 yards on a good day. get this gun,it rocks! btw,it is not wobbly at all,it is a very sturdy,realistic airsoft weapon.
