I ordered this gun and it came within a week. I just received it yesterday and i am truly amazed. The more i looked at it, the better it got! The construction is amazing, the only wobble is from the crane stock, but it isn't much. I tried to flex it and it didn't. It is made to perform both internally and externally. The logos are better in my preferance because there was a clown on the side but thankfully they changed it. The gun replaced my aim top sportsline m4, so i took the 6.01mm tightbore barrel from that and it is the most accurate m4 i've used (it didn't need the tightbore barrel). When i got mine it was signed by G&G and they said that it shot 350fps, which is great! If you want to play CQB just change out to a smaller barrel, but when playing field put in the stock or make it a DMR, thats why i love m4s!
