I have two friends with the Echo 1 M28 and it is almost impressive I guess you could say. One friends gun was shipped to him and it didn't work right off the bat cause either the gun or (both) mags had a feeding problem. They did send him a new one for free though and that one works alright for now. The other friend had one that worked but broke over time. Sadly, it didn't break the whole gun, just little parts of it that made it the most annoying gun to use in the world. Sometimes it would slam-fire, sometimes the slightest touch of the trigger would shoot it, sometimes the trigger would get stuck and to shoot it you had to push the trigger forward, and sometimes, it wouldn't shoot and you had to pull the safety back and forth and pushing it back into "fire" would make it shoot. Needless to say, when I was using this, it cost me a lot of kills and got me killed more often than I want to admit. Seriously the most annoying thing ever. When it does work though, its an alright gun.
