Years ago when they wanted to "ban" ARs I didn't understand why everyone was going out to buy one.
My thinking was if the item was banned you couldn't own it so people were essentially throwing money away.
The guy at the local gun shop explained that "ban" meant they just couldn't sell them anymore but the people could keep the ones they already purchased.

Now they are banning slide fire and crank fire items and indicating that owning one would be a federal crime even if purchased a while ago.

When does "ban" mean, you can no longer buy an item BUT can own what you already have?
When does "ban" mean, you can no longer buy an item AND can no longer own what you already have?

The term "ban" is defined by the legislative language associated with the ban.  In other words, it means different things in different regulations/statutes.

The 1986 Hughs ammendment banned the future tansfer of NEWLY manufacture machinguns to "civilians."  Machine guns manufactured prior to the ban can still be possessed and transferred.

The 1994 Clinton AWB banned the sale of newly manufactured, so called "assault weapons," to anyone other than LEAs and Military. Guns manufactured prior to the ban could still be possessed and transferred.  Since there was no such thing as an assault weapon, the term "assault weapon" was created by and defined by the ban's language.

Florida's new ban on devices that increase the rate of fire of semi-automatic firearms (bump stocks) prohibits the possession of the device, in Florida after October 1, 2018.  The law includes NO provision for compensation. So, you get rid of your device or become a felon.  The language of the statute expanded the definition of "bump stocks" well beyond the common, commercial meaning of the term.

A number of years ago Florida banned ballistic knives.  Again, no compensation.  If you possess one you are a felon in the state of Florida.

Florida bans some types of ammunition.  Looking closely at the statute however you will see that there is no ban on the possession of such ammo unless you actually load it into a firearm.

So, there is not one answer to your question.  We won't know until we see the actual legislation.

I can tell you that the gun-grabbers learned from their "mistakes" in the 1994 ban and any future ban will include a POSSESSION clause if they have their way with us.

Yep, depends on the definition(s) of words used in the statute... as to what "ban" means.

You can ban possession, sale, transfer, manufacture, alteration, etc., with statutory exceptions as complex as the mind can conjure up.

Thanks.
From my understanding is that its official and includes both slide fire as well as the crank fire items?
If this is correct, what is the date that it comes into effect?

The “bump-fire” ban is absolute and goes into effect October 1st, 2018; the ambiguous verbiage of the ban could be interpreted to include any part of the rifle that increases the rate of fire from another, potentially virtually banning all semi-auto firearms in Florida.  It may take court precedence to determine the extent; Time will tell.

In the mean time, it may be wise to educate oneself on which elected officials voted for this, so as to vote these vermin out of a job if and when they try to get elected again.

This is of course is all new.  To the best of my knowledge, this is the new statute...

Effective Date: October 1, 2018

790.222 Bump-fire stocks prohibited.—

A person may not import into this state or transfer, distribute, sell, keep for sale, offer for sale, possess, or give to another person a bump fire stock. A person who violates this section commits a felony of the third degree, punishable as provided in s. 775.082, s. 741 775.083, or s. 775.084.

As used in this section, the term “bump fire stock” means a conversion kit, a tool, an accessory, or a device used to alter the rate of fire of a firearm to mimic automatic weapon fire or which is used to increase the rate of fire to a faster rate than is possible for a person to fire such semiautomatic firearm unassisted by a kit, a tool, an accessory, or a device.

Gun laws don't eliminate guns, they only criminalize their possession.

Nothing is actually banned, you're  just deemed to be  a criminal due to the stroke of a pen.

The problem I have with this law is the vague language.  Per the law, crank fires are bump-fire stocks.  The ATF has deemed crank fires as Gatling guns.  So if crank fires are now bump stocks, are real Gatling guns bump stocks as well?  I can bump fire stock firearms without any addition device.  Does that firearm become a bump stock just because it can be bump fired without modification?  Lot's of questions...

Can you sell it before that date if someone has some?

Of course, but who in their right mind would buy one with DOJ talking about banning them... You would obviously want to be smart and sell it to someone out of State if it is legal in their State.

I’m not a lawyer but I’m pretty sure criminalizing something you are already in possession of does not meet constitutional muster (RKBA aside).  I realize some commie states may have done this already (doesn’t mean it is constitutional) but this sort of thing doesn’t really work out, IMHO.

Not to sound like I am on "their" side, but...

They are not criminalizing past possession.  They are criminalizing future possession after October 1st.

If they were criminalizing past possession, they would obtain a warrant for anyone who ever owned one and arrest-on-sight, even if you were no longer in possession.

More than likely written that way on purpose in order to entrap as many gun owners as possible.

Could an adjustable stock , better trigger, lighter trigger springs, different weight buffer etc...all be considered a type of bumpstock device by a anti-gun sheriff or prosecutor?  Very possible.

I guess these political idiots thought or think that if they ban but grandfather say a 500.00 AR we'd not bitch as badly
VS
Banning a trigger and BCG that cost 500.00 and telling you that if you do not throw it in the garbage your a felon and at that point we can come and take all you guns and ban you from ever owning guns AGAIN.

One is Just stealing your rights, while the other is stealing both real property and your rights

On top of those things above they are threatening to make you a felon and take your rights away for ever.

No paying you for that 500.00 property or allowing you to sell,it where it's legal to own.

You know exactly what he means so quit twist words.

NO, I didn't know exactly what he meant or I would not have said anything.  And, I did't twist anyone's words.

I was just explaining why, in my opinion, the new law was not Ex post facto.

And I certainly was not expressing any support for the new law.  I think it sucks as much as you do.

We are all emotionally invested in this knee jerk legislation and our frustration is showing. Let' not start infighting.

I believe it's time WE THE PEOPLE BAN THOSE ELECTED OFFICIALS THAT VIOLATED THEIR OATH TO DEFEND THE CONSTITUTION. INSTEAD THEY ARE ATTEMPTING TO DESTROY IT. BOTTOM LINE, IT'S ALL TO GET ABSOLUTE POWER OVER THE AMERICAN PEOPLE.

Then destroy them. These so called elected officials are actually violating the bill of rights with these laws. But we let them do it.

We let them as Hillary said regulate our CONSTITUTIONAL RIGHTS.

Right out of existences. Extreme I know, but what they are doing is worst. This is getting ridiculous and right out criminal. But they control the courts also.

Just as in Florida with this taking of guns without DUE PROCESS. They said we will get that later. That's a violation of the 5th and 14th Admendments.

But what do they care. They are the government. They can do what they want. They will fight us with our own money in court. They make felons instantly simply by ownership.

Those bump stocks, binary triggers can cost 500.00 or more. They want people to just destroy, throw away their money. Knowing that none, nothing not one law they've pass will prevent anything, stop one shooting.

These are worthless laws and a violation of our rights. They are taking personal property without compensation. 500.00 is alot of money to steal.

Watch this is just the beginning. Magazines and other items will be next. Plus no more YouTube instructional videos on anything guns.

Yet you can watch videos on how to build bombs. This is a right out attack on innocient American gun owners. This is far worst than just a ban. POLITICAL LEADERS and every every LEFT Wing SOCIALIST  extremists that has any kind of power or outlet has also.

Where were these people when Obama was President. Why now......where are they drawing their energy from. The NEWS MEDIA is nonstop attacks against the President and conservative gun owners call us all crazy.

Simply for believe in what made America, America. The CONSTITUTION and BILL of RIGHTS. They say if you believe in those documents you are extremist and terrorists in some cases.

This is way way worst then any ban I've ever seen imposed. They want to wipe out everything, destroy the Bill OF Rights.
