6mm
The most common size for BB bullets, particularly in airsoft and BB guns, is 6mm in diameter. This size is widely used in recreational shooting and is compatible with most airsoft guns. In traditional BB guns, lead or steel BBs typically measure 4.5mm in diameter. Each size serves different purposes depending on the type of gun and intended use.
6mm of either .12 or .20 gram bbs. 6mm of either .12 or .20 gram bbs.
I do not know of a production airsoft gun that shoots bbs of those dimentions but it doesnt mean its not out there As you probably know, most common is 6mm, and some airsoft guns, specifically some revolvers, shoot 8mm bb's, but I have never heard of a 7mm bb or a gun that shoots it.
airsoft uses 6mm bbs. Perhaps you are talking about weight? .20 gram is good.
it was 3'4 ft long.
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)
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.
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.
you can not use metal bbs in airsoft guns at all. they are not compatible because they are both built differently.
