This gun is EXTREMELY solid. When I first took it out, it felt so amazing. Basically the whole thing is made out of all black great quality metal. The included front grip is very durable and useful, and the included magazine feeds great and holds 550+ rounds. The LE stock is awesome on an AK, the customization is very useful. The top back rail is screwed on to the AK in a very secure way. You can easily unscrew it if you prefer or when you need to change out the battery.
I used this gun yesterday in a small game between my friends and I, and it basically out shot everyone else's guns in terms of accuracy, range, and pure FPS. I took this gun to the local airsoft shop and they clocked the FPS at 447. Yeah, it's amazing.
-Awesome accuracy, even at long ranges
-Very solid construction, nothing wobbles
-447 FPS on mine
-Full metal, extremely durable ABS plastic on the rest
-447 FPS might be too hard.. for some people
-Black paint on the metal body can scratch off, but that's not too serious
