This is an excellent gun. Very sturdy, heavy, and powerful. I have had it for about six months and it is still running solid. The gearbox is difficult to get to, because the button that releases the stock has a rod going through the gearbox, and I haven't found a way around it. In the new version, Echo 1 has kindly glued on the pin to remove the flashhider, which is metal and really isn't that bad. I checked on their website and they treated everyone like crap who asked them how to take it off. I am going to put it in the oven tonight and see if that helps. Otherwise, solid gun, amazing price.
400 FPS constant
Strong polymer (only three pieces aren't metal)
Feeds well with CA midcaps
Side rail mount
Flash hider predicament
Other mags are very wobbly
Sling mount is clangy ( I took it off)
Flip sights are exactly the same!!!!
