If it is Tokyo Mauri compatible it can be upgraded with practicaly anything you can imagine ;)
ABS plastic is used quite often in airsoft guns, especially in guns made in China. The strongest plastic in airsoft is probably the plastic used on the Real Sword Type 97, which is advertised as "high strength polymer material" but is really the same plastic used on the real steal Type 97 (since both the airsoft and real steel versions are made by the same company it is probably the best built airsoft gun externally short of a CTW or PTW). In the market it is often hard to tell which guns have high quality plastic and which have cheap plastic because it is all advertised as high strength or high quality polymer. The best way to tell is to go to an airsoft store and feel it for yourself. Also, the price of the gun is usually a dead giveaway, because any gun with really good plastic will be over $300.
Made out of plastic
Airsoft is legal in many countries. Any gun that shoots plastic pellets are airsoft guns.
so are some arent
I'd recommend the Double Eagle M83. It's a good gun with a plastic gearbox. The gearbox cannot be upgraded but you should be happy with its performance. Its really cheap, around $40 and you'll like it. Its all plastic but pretty accurate. Hope that helps.

If the gun is spring then it is most likely not automatic but if its electric it is most likely automatic.
Sounds like you are looking more towards BB guns. Check out the BB (not airsoft) rifles instead.
it is automatic but you can go semi-auto
Airsoft guns often replicate real guns (such as M16, AK-47, ect,) and shoot little plastic pellets. Airsoft guns are commonly used for the sport of airsoft, which involves a simulation of war where you try to get the other players "out" by shooting them.BB guns are not meant to shoot people. They are single-action where airsoft guns are commonly automatic. They shoot small metal BBs which are generally meant for target practice. They generally have a higher velocity than airsoft guns and are dangerous to shoot at people but are not capable of killing anyone.
no, it doesn't
