You will need 6mm plastic BB's. These can be gotten at most sporting goods stores these days.
*There are also airsoft guns that shoot 8mm BB's. These are quite rare to see in the United States, so I'm betting that your gun is 6mm.
.177 cal metal BB's or .22 cal metal BB's won't work in your airsoft gun.
Any airsoft gun. Yes
Airsoft bbs are made up of plastic and are 6mm in diameter and are .24 cal, BBs however are metal and are .177 cal (4.5mm)
Type recommended by the maker of the airsoft.
The stinger p9 is good with .12 gram airsoft BBs or you can use .25 gram bbs but then it will decrease the range.
No. It's not designed to shoot them.
You can buy airsoft paintballs, but they're the size of a small pellet and I've had a hard time finding them. Technically no. There are NO paintballs that work in an airsoft gun. The answer above was partially correct though. They make marker bbs that are basically bbs but they have paint on them.
you can not use metal bbs in airsoft guns at all. they are not compatible because they are both built differently.
any bbs will work in any gun i prefer .20 gram crossman whites
no
yes they are very accurate
Most airsoft guns have magazines that you put bbs into just like you put real bullets into a real gun's magazine
.25 Airsoft bbs can be good. Their weight is very good for accuracy and helps for a harder hit from the bbs. However, no bb is good if they are not high polish. Companies like Madbull and Matrix make good .25 bbs.
