To make the BB's go faster, all you need to do is lower the weight of the BB. The lowest weight of a BB is 12grams. If you already shoot with that then you probably just have a cheap gun.
email me at vino12@aim.com if you have anymore questions about airsoft or real guns and their ammunitions.
He is right about the BB's another way you can increase speed is with a bigger and stronger battery. I highly recomend using Amazon there batterys work fantastic and are cheep as DIRT.
To go along with both of those answers-If you have a bolt action or spring airsoft gun, a spring upgrade from online sites like evike.com or airsoftmegastore.com can increase the speed greatly.
Tight bore barrels can also increase your fps by about 15%. They also make it much more acurate
no. Airsoft guns could not possibly shoot that fast.
If you use airsoft gun in public place or pretend it's a real gun - yes, you can be shoot. Do not use airsoft guns in public places!
Yes.
Keep it clean and get a stronger spring.
Because you, my friend, have a broken airsoft gun.
You need to lubricate and clean it.
A gun that cocks back automatically after you shoot.
Depends on the laws
YES
no, it doesn't
NO- they shoot large diameter plastic BBs. In general, they do not have the power of the traditional BB gun.
in your own back yard, airsoft guns are legal on your own property to shoot, as long as your not shooting someone else who doesnt want to. its perfectly legal to shoot and use any airsoft gun no your own property.
