@hightor,
The reason I used those 2 specific guns is that they are the exact same gun with different cosmetics. Fire the same bullet at the same caliber at the same speed and rate of fire. There is absolutely no difference other than cosmetic features.
I guarantee that 4 out 5 gun banners would choose to ban the bottom one while thinking the top one was less dangerous.
Normal people don't shoot from the hip unless they are actors in a movie. A pistol grip, if you have ever held one at waist level, is harder to control then a non-pistol grip rifle due to the way your arm and wrist are shaped. Try with a broom or something.
Calling something "assault style" is like calling a car "sports like". It either is an assault rifle or it isn't. Cosmetic appearances do not define an assault rifle. It's like puuting a wing on the back of a beetle and calling it a Porsche.
