Everything is metal EXCEPT for the stock(**SEE CORRECTION BELOW). Nothing else is plastic, really. Remember the VSR-10? Same principle. Everything that should be metal, are made with metal. The stock is ABS. Wood impression is same type as the VSR-10 real shock.
The body is VERY solid. the gun is over 3Kg in Weight. On an 8.4V 1800mA Large Battery the rate of fire is very fast (similar to P90 rate of fire). The muzzle sound sounds like an AK 47.
I don't have a lot left
PS: Hey how come it says my trader rating is ZERO? lol...!
** I appologize for giving in-accurate info. There's one ABS thing that's supposed to be metal. It is the rippled heat shield kind of thing covering the inner barrel (You can see it clearly on the second last picture on the first message).
