Right out of the box this gun is very sturdy and the metal construction has a nice feel. The crane stock and flash hider are both plastic. That being said, the stock seems very strong and has held-up well so far, though there is not a huge amount of battery space, what is there will do fine. The flash hider on the other hand is quite cheap. Within the first month, one of the four end points broke when the gun brought up and nocked on something. I suggest purchasing a metal replacement. Once you get a 1/16 allen tool the screw on the flash hider losens quiet well and the flash hider is easy to remove. The internals are very strong and are a bit loud, which is absolutely not a problem. With .23 goldenball proslick BBs it chronoed at a steady 370, it will most likely reach 400 with .20s. The rail covers are OK, if you are picky about things like that, buy new ones because they are not the highest quality. Overall I give it a 5 because there isn't much to complain about once you fix/replace some minor external items.
FPS-370 with .23
raised rail piece
free vert. grip
lots of rail space for customization
somewhat loud (good for intimidation)
plastic flash hider
rear iron sights are a very small peep sight (small hole for ranged shots)
battery is an 8.4 1100mah, you may want a new one for long games, but the stock one will work fine.
