A bb gun pretty much works the same way as a spring airsoft gun. But the differences come in the activities of how they are used. A bb gun is used for target practice, but ever since bb guns have been created, people have been using them for fighting, like in a paintball or airsoft fight. Of course this lead to alot of injuries, (Just like in A Christmas Story). Airsoft is a whole lot different. I play it and I know alot about it. First of all airsoft is more intended for battles, like in paintball. Second of all, they shoot plastic bb's instead of metal ones, therefore having less chance of injury. Also most airsoft guns are replicated off real guns like AK-47's, M4's, Desert Eagles, MP5's, and much much more. And if played responsibly it can be a very exciting and fun activity. I started out having just backyard airsoft fights with local neighborhood friends. And now im playing professionaly at battle re-enactments, and batles. Those are the some of the differences between airsoft and bb guns.
If you are talking about airsoft bb's, then yes. Most bb's fall between .12 grams and .30 grams, and a 20 gram airsoft bb wouldn't work well.
yes, most green airsoft bb's are biodigradable
No. Metal bb's will not work in airsoft guns.
bb
Yes, the only difference is their weight.
Are you asking about BB guns or Airsoft guns. There is a difference. The LAST thing you want to do is shoot at someone else with a BB gun.
almost every gun for airsoft uses a 6mm (milimeter) BB. try that.
The Colt 25 airsoft BB gun cost between $10 - $15 depending on the model.
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."
Without the weight of the airsoft BB, it is impossible to answer this question as Force is affected by the mass of the projectile.
FPS depends on the type of bb used, quality of the bb, weight of the bb, and the chronograph. On top of that, it depends what shotgun it is! There are many, many airsoft shotguns out there.
If you are asking about Airsoft BB shot in a regular BB gun that shoots metal BB, then the answer is NO. Real BB guns fire at a much higher rate than most Airsoft BB guns. The plastic BB could disintegrate and become flying pieces of Plastic.
