6mm bb is the size, and the .20 means the weight. They are usually measured in grams rather than ounces. You can get a variety of weights, but generally they are all the same size - 6mm. The weights are .12 gram, .20 gram, .25, .28, .30 grams are the most used. .12 grams are the lightest and usually come with cheap guns. Use .20 grams and buy a decent quality, rather than from a big box store. Go to a reputable airsoft store for your bbs. Cheap bbs will cause gun breakages.
6mm of either .12 or .20 gram bbs. 6mm of either .12 or .20 gram bbs.
airsoft uses 6mm bbs. Perhaps you are talking about weight? .20 gram is good.

All airsoft guns usually use 6mm BBs, usually made of plastic, and come in a variety of different weights (.12 grams, .20 grams, .25 grams, .28 grams). Normally .12 gram BBs are the cheapest, and are good for most airsoft guns, although airsoft guns that shoot at higher velocities should use .20 or .25 gram BBs, as they will shoot straighter.

6mm .12 gram or 6mm .20 gram BB's are recommended.
All airsoft guns fire the 6mm plastic projectile. If you are talking about weight, all will work, but steer from .12 gram BB's. Any others, like the .20, .23, .25, ect, will work fine.
Yes. .12 grams is the weight of the BB, not the size. Almost all airsoft guns use 6mm BBs. .20 gram BBs are heavier and reduce distance and velocity, but increase accuracy. .12 gram BBs will fire with more velocity, but there will be more spin on the BB and less accuracy.
I think you mean grams. They come generally in .12 gram, .20 gram, .25 gram .28 gram and .30 gram and a few higher grams than that. Grams are a weight measurement so that should answer your question. Most people use .20 grams in an AEG and .28 or .30 for sniper rifles. 24 caliber I believe means 6mm bbs which is the standard size bb for airsoft.
$20 or so.
There is only one number that equals 20, and that is 20.
Yes some airsoft guns can kill birds
