THe most dangerous airsoft gun is probably any of the Systema PTW series if they have the highest power cylinder. With it they can shoot at approximately 700 fps. A highly moded gas sniper rifle may also be able to achieve similar power, but I am not aware of any other airsoft gun that can shoot over 500 fps stock. Also, the Systema PTW has an absurdly high rate of fire, so it can deliver bb after bb. Most people who use these guns us weaker cylinders though, so in an airsoft game you will never have to worry about anything over 500 fps, and most guns will be around, if not lower, than 400 fps.
Both can be dangerous if used improperly
Neither
The best way - go to near airsoft workshop, give them money and tell what do you want. If you decide to modify airsoft gun by yourself - be warned, this may ruin your gun and even be dangerous to your health.
the only real danger is if you get one in the eye but even then its proven it takes 1joule airsoft to punture the eye
Most states follow the Federal guidelines for Airsoft - You must be 18 or over to purchase and own an Airsoft gun. Persons under the age of 18 can only own an airsoft gun with parental consent.
An Airsoft gun
Neither, all guns are violent and dangerous.
No, airsoft guns are toys. They use batteries and gearboxes to fire 6mm plastic bbs at an average of 2 joules. Although many high powered air rifles can be as dangerous as real guns, they should not be confused with airsoft guns.
It isn't dangerous to get shot with any time of airsoft gun if it isn't in the face. I use a 400fps HPA (High Pressure Air) powered Mark18 and I shoot my friends all the time. most spring airsoft guns are only about 100 or maybe 200 fps. So long as proper eyewear is worn it should be no problem.
A pump airsoft gun is a gun that has to be pumped every time before shooting. Ex. Airsoft shotgun
No
Most airsoft guns have magazines that you put bbs into just like you put real bullets into a real gun's magazine
