Air Soft guns are not designed to fire Pellets. The shape is just wrong but there are steel BB in the 6mm size avalable. But because they are heaver than plastic they fire or travel slower. If the Air Soft gun is not designed to use them they may actually ruin or break the air gun.
Air rifles use compressed air or C02 to propel the BB or pellet. They do not use gunpowder. Their is no bullet shell and bullet just the BB or pellet.
Setting aside how DANGEROUS and IRRESPONSIBLE this would be, for the amount of money it would cost to do it safely (if that's possible), you could buy a real firearm
A pellet rifle has no firing pin. It also can not fire a bullet or gunpowder. It can not be made to do so either. The pellet has no charge (casing like a bullet) it just a pellet. However pellet rifles can be just as deadly as a real firearm. They use Air or C02 to project the pellet downrange. Some Pellet rifles are used for hunting, others for target practice. The Major difference between a firearm and an air rifle, is Gunpowder is use in Firearms and Air or C02 is used in Air rifles.
A regular pistol is a firearm. It uses gunpowder to fire a bullet. An air pistol uses compressed air to fire a pellet with less velocity than a firearm.
Some AUG assault rifles can be modified to be smaller and fire a smaller caliber of bullet, but these are not true submachine guns.
Any air gun or rifle that uses a .177 Caliber pellet can use the Gamo .177 Red Fire Pellet. No matter who makes the air gun. The Caliber .177 is universal to all .177 caliber pellet guns or rifles.
When you shoot a bullet the bullet casing pos out through the ejector and that is where the bullet is and gunpowder to fire it.
it is impossible to fire a bullet a the speed of light
Yes.
CO2 pellet guns work by using CO2 for rapid fire, with CO2 the gun does not need to be pumped or recorked after every fire. You can also find spring loaded pellet guns.
Rim Fire bullets (Rifles or guns) require a firing pin that strikes the bullet casing and the resulting explosion of gunpowder in the shell fires the bullet out of the barrel. Air guns have NO firing pin. An air valve or piston forces air or C02 into the barrel behind the pellet or BB and this shoots the projectile out of the barrel.
At least ten feet thick. This would depend on the weapon used to fire the bullet - an airgun pellet wouldn't require much of a wall, whilst an armour-piercing round from a high-velocity rifle would require a very thick one.
