For all semi-auto weapons capable of penetrating a typical law enforcement ballistic vest at 10 yards or with a muzzle exit velocity in excess of 1500 fps. No firearm sales to anyone under 21.

“assault” weapons.

Assault rifles and handguns. Attach serious prison time to possession.

but I have yet to see one person explain how it would be done. Want to give it a try?

In a nutshell; make them illegal, give a one year grace for buy-back/turn in then jail anyone in possession.

Only what I'd like to see.

#1 This is not Australia. No other country on earth has as many guns as America. Also in AU it is NOT illegal to own a gun for hunting. However, self-defense, IS illegal.
#2 Exactly who do you expect would do the job? We would need hundreds of judges to issue MILLIONS of search warrants, unless you plan to repeal the 4th as well, then hundreds of ARMED men to take them by force - BEFORE they could organize. Old enough to remember Waco??

for self-defense or hunting. But more than that, AR15s and similar, pubic toting, and such, we are just asking for more mass shootings, three percenter and other white wing militia/racist group uprising, intimidation, crime, etc.

I think registration is necessary.

And, I'm fine if so-called responsible, law-abiding gun owners, end up in jail or heavily fined if they don't comply with laws we all know are necessary.

Okay, here goes (and please bear with me until the end)

1. Grandfather the assault-type weapons already owned (AR-15s, etc.): if you own one, you can keep it.

2. A two-year federal-level ban on sales of these weapons, accessories, and ammunition to the general public.

3. A two-year federal-level ban on using or showing these weapons by the general public, including demonstrations and shooting ranges.

4. Two years of automatic confiscation of any of these weapons or ammo visible in public.

A privately funded study to examine gun violence during the two-year period. Who funds and runs it? I'm not there yet.

Depending on the study results, the potential for a permanent ban on sales of these types of weapons to the general public.

Look, I qualified on an M16A1 back in the Army. I thought it was a cool device, especially when shooting auto. I almost bought an AR-15 a couple of years later. I never did. And I know people who own AR-15s and keep them locked up in a gun safe. But these things have gone beyond "a cool toy to use at the range" to some kind of symbol of power and expression of hate. I think it's time for gun manufacturers to re-tool and come up with a "cool toy" that can't do as much damage.

Without gun registration, and both background checks and registrations have to be universal and kept on state and federal databases (which is illegal under federal law currently and hard to find enough courageous politicians at a local level).

Even under the Brady Bill, with background checks for FFL sellers, if the ATF doesn’t come back within three days, the sale can go through. Maybe the FFL clerk doesn’t see someone suspicious, or maybe they’re just greedy, and they let the sale go through. Without the database of guns and their owners, it’s also impossible to tell precisely where and from whom all of those illegal guns in Bogeyman Chicago are coming from — some good ol’ boy just needs to drive to a gun show in Missouri or Indiana every weekend and buy from whoever will sell them, then drive back to Chicago and turn a blood-stained profit.

Yet another problem with the current Brady Bill is that thousands of people are rejected every year, and there are virtually no prosecutions. It’s up to the state’s politically appointed federal attorney on how to enforce that law, or how stringently. They don’t want to piss off the NRA or throw lots of white people in jail, so usually the gun seller just says “No, you failed the background check” and nothing happens. A few highly-publicized, lengthy-prison sentences, and people would think twice.
