After reading my review, I realized it cut off my list. Before I continue, I'd like to post it the way it was meant to be posted;
The following things denote an "Assault Weapon". They apply only to semi-automatic rifles;

1. Detachable magazine
2. Collapsible stock
3. Folding stock
4. Pistol grips
5. Bayonet lugs
6. Threaded barrels, allowing for additions of compensators, sound suppressors, and muzzle brakes
7. Grenade launcher
8. Barrel shroud
9. Magazines greater than ten rounds
10. Semi-automatic firing mode

I apologize for any confusion regarding the list.

Now, for my review. You raise many excellent points, most of which I agree with. My only problem is the studies you talk about. While I don't deny that such studies exist, you need to provide a source-not just for me, but for everyone. Other than that, I really have nothing else to say.

I agree, up until you say I shouldn't own an "assault weapon". Here's why;

1. "Assault weapons" are better at home defense than most handguns. A 9x19 round tends to over penetrate, and has the potential to go through multiple obstacles without even slowing down. This means that it carries a risk of inflicting injuries on other innocent people. A .223 round (used in the AR-15) has great stopping power, but little penetration, making it an ideal home defense round.

2. "Assault weapons" carry more ammo than handguns. A 1911 holds seven rounds in a magazine. Glocks hold twenty. Ar-15s, WASRs, and VZ-58s hold thirty. I'd rather not be forced to waste even a second reloading a five-shot magazine in my rifle. Someone hopped up on meth isn't going down with one shot. I've seen videos where people have taken several mags from a handgun, and not gone down. I'd rather not have to reload in this situation.

3. "Assault weapons" are used very little in crime. Something like 4 percent of crimes on average are committed with one.

4. "Assault weapon" is a false term used by gun grabbers as a fear mongering tactic. When people use it, they usually refer to weapons like the AR-15, because of their "military-style" appearance. It has nothing to do with functionality. It's not an assault rifle, because those are capable of going full auto, and full auto weapons made after 1989 are either illegal, very rare, or very expensive. "Assault weapons" are actually battle rifles, which are defined as rifles that are not capable of going full-auto, yet still classify as rifles. So, what constitutes an "Assault Weapon"? Here's the list;

magazines.
stocks allow for adjustment to the length of pull to the shooter's preference.
stocks reducing the total length of the firearm, making it easier to transport.
grips (on rifles).
mounts allow the mounting of a bayonet. (illegal)
suppressors reduce night vision degradation to a shooter's vision, as well as those beside or behind the user.
barrels allow for the mounting of flash suppressors, compensators and muzzle brake
mounted grenade launcher mounts are concentric rings around the muzzle that facilitate attachment of rifle grenades. (illegal)
9.A barrel shroud is a tube around the barrel designed to limit transfer of heat from the barrel to the supporting hand, or to protect a shooter from being burned by accidental contact.
greater than 10 rounds..
-automatic, functionality meaning that they can eject spent shell casings and chamber the next round without additional human action, but (as opposed to automatic firearms) only one round is fired per pull of the trigger.

Many of these are defined based only on appearance, not functionality, and I can argue that I need a lot of them to properly use a rifle. I need semi-auto fire to swiftly deal with any threat that doesn't go down in one shot. I need a mag with more than 10 rounds in case there's more than one person threatening me. I need a pistol grip to properly aim my rifle. I need a detachable mag to quickly reload. I need a barrel shroud so I don't burn my hand when putting rounds through my rifle. I need a flash suppressor so my eyes are protected when shooting my rifle in a dark environment, such as at night. I need a sound suppressor (silencer) so my ears are not damaged when shooting my rifle in a confined space (such as in a house). I need a threaded barrel to mount those two suppressors. I need a collapsible stock to maneuver around tight spaces in a confined area.

Bayonet lugs have no reason to be banned, because bayonets are no different from knives. Also, I have yet to hear of anyone being murdered by a bayonet.

Grenades are classified as destructive devices by the ATF, and are illegal. Therefore, the grenade launcher should not even be on the list, as grenades compatible with them are already banned.

So, explain to me again why I shouldn't be allowed to own an "Assault weapon"?
