I haven't bought an airsoft gun from this web sit. It cost $25 and looks legit. But i don't know it seems to good to be worth it.
Plastic or metal? Full size or half size? It would vary depending on the actual gun you are trying to talk about. Try anywhere from 1 lb - 10 lbs.
No.
6mm
If there's varying sizes of airsoft pellets, then each size will only work for airsoft guns intended to take that size pellet. Others will be either too small or too large, and could end up damaging your airsoft gun, or even getting stuck in the barrel.
BB's for air guns (NOT airsoft) only come in one size .175 commonly referred to as .177 caliber. If you want to know about airsoft BB's then you need to put the question in the "Airsoft category."
No it depends, you need to check the rail size of your rifle, then the sort of rail that the scope can attach to. These are some standard airsoft scopes, check your gun rail size first though!

airsoft uses 6mm bbs. Perhaps you are talking about weight? .20 gram is good.

No, only with a few Marui selected models, or with airsoft guns that have a threaded barrel of the same size.
