There's nothing necessarily wrong with AW- I've heard both good and bad things about them. If I were you I'd go for a G&G M4 instead. I loved my CYMA MP5 but the quality difference is really noticeable
I was looking to get a CM16 carbine style rifle, but wanted something different from G&G as all of my guns so far have been G&G and also i wanted to save as much money as i could so i can get the Magpul/Vltor lower and upper
The only way I WOULDN'T get another G&G would be if I had enough to get something better (TM Recoil SOPMOD you WILL be mine). If you're looking to save money there's plenty of CM16s about - why not get a second hand one if you're going to mod it anyway?
