Guns are designed to fire a projectile.<quoted text>
You changed from "intended" to "designed".
Try to be consistent.
Guns, except for purpose built, high precision, competition guns, are DESIGNED to kill.
They may well be, and are, bought for entirely different INTENDED purposes, such as plinking or target shooting.
But that in no way changes the fact that they are DESIGNED for killing.
And assault weapons, regardless of their INTENDED use, are DESIGNED for killing as many people in as little time as possible.
Guns are intended to fire a projectile.
What one shoots the projectile at is not the design or intent of the gun.
