The gun is made of plastic, and the stock is weighted that adds a more solid feel to the gun. To make the gun work, you just pour some bbs into the top of the gun and pull back on the pump action then pull the trigger. When you open the box you will find the bb gun in 2 parts (the stock and the barrel), the parts easily and quickly just push together with no need for any screws or bolds etc. (The real version is the Russian made MTs255 made by TsKIB SOO Central Design and Research Bureau of Sporting and Hunting Arms. This is a cheaply made pump action shotgun that's about half scale in size to a real pump action shotgun.
