EDITED TO ADD:

The final bill (SB1160) was passed and signed into law by the Governor.  It is oficially listed as Public Act 13-3 and is available in full here.

So senate bill 1160 was tweaked a little. It's not accurate. Only review Public Act 13-3

Here are the new laws. SB 1160

Perhaps the moderator can un tack the old law as it is no longer valid.
It's a very large bill. This is a copy and paste of the new laws about AR15s, pistols and magazines.

§§ 23-24 — LARGE CAPACITY MAGAZINES

The bill defines "large capacity magazine" as any firearm magazine, belt, drum, feed strip, or similar device that can, or can be readily restored or converted to accept, more than 10 rounds of ammunition. It excludes:

With exceptions, the bill makes it a class D felony to buy, distribute, import into Connecticut, keep for sale, or offer or expose for sale LCMs.

With exceptions, anyone who possesses any LCM on or after January 1, 2014 obtained before the bill's effective date is guilty of a infraction punishable by a $ 90 fine and a class D penalty for any subsequent offense; anyone who possesses a large capacity magazine on or after January 1, 2014 that was obtained after that date is guilty of a class D felony.

Exemptions from the Ban

The following may possess, purchase, or import LCMs:


1. members or employees of DESPP, police departments, DOC, or the Armed Forces (service members) (a) for use in the discharge of their official duties or (b) when off duty;

2. employees of a NRC licensee operating a nuclear power plant in Connecticut for providing security services at the facility, or any person, firm, corporation, contractor, or subcontractor providing security at the facility; or

3. in-state manufacturers of LCM that manufacture or transport LCMs in Connecticut for sale here to exempt persons and entities above or for sale out of state.

The following may also possess LCMs:


1. gun dealers;

2. gunsmiths employed by gun dealers, who possess LCMs for servicing or repair;

3. anyone who declared possession of the magazine under the bill; or

4. executors or administrators of an estate that includes legally declared LCMs, which are disposed of as authorized by the Probate Court, if the disposition is otherwise permitted.

The bill allows transfers:


1. by bequest or intestate succession of LCMs, declared to DESPP;

2. to DESPP or a local police department; or

3. to gun dealers in compliance with the bill.

Violations

The court may order suspension of prosecution of a violation of the LCM provisions in accordance with the bill if it finds that the violation is not serious and that the violator (1) will probably not offend again, (2) has not previously been convicted of a violation of the provisions, and (3) has not previously had a prosecution for a violation suspended.

Declaring Possession of LCMs

Anyone who lawfully possesses an LCM before January 1, 2014, must apply to DESPP by January 1, 2014 to declare its possession in order to legally keep it. Service members unable to apply by January 1, 2014 because of out-of-state duty have 90 days after returning to Connecticut to declare possession of such magazine. Applications must be made on such form or in such manner as DESPP prescribes.

In addition to the prescribed LCM application form, DESPP must design or amend the applications for existing gun credentials to allow an applicant to declare possession of an LCM upon these same applications. DESPP may adopt regulations to establish application procedures.

Name and Address of People who Declare LCMs Confidential

The name and address of people who declare possession of LCMs are confidential and disclosable only to (1) law enforcement agencies and U. S. probation officers carrying out their duties and (2) the DMHAS commissioner to carry out statutory provisions pertaining to gun laws.

Nonresidents Who Move to Connecticut

Anyone who moves into Connecticut in lawful possession of an LCM has 90 days to either permanently disable it, sell it to a gun dealer, or take it out of state. But servicemembers who transfer here after January 1, 2014, have 90 days after their arrival to declare possession of an LCM.

Transfers to Dealers

If an owner of an LCM transfers it to a gun dealer, the dealer must, at the time of delivery, execute a certificate of transfer.

For transfers made before January 1, 2014, the dealer must give DESPP monthly reports, on such form as the commissioner prescribes, on the number of transfers that the dealer has accepted. For transfers made on or after January 1, 2014, the dealer must send or deliver the transfer certificates DESPP. The certificate of transfer must contain:


1. the sale or transfer date;

2. the gun dealer and transferor's name and address and their Social Security or motor vehicle operator license numbers, if applicable;

3. the gun dealer's federal firearms license number; and

4. a description of the LCM.

The gun dealer must present his or her dealer's federal firearms license and seller's permit to the seller or transferor for inspection at the time of purchase or transfer.

The DESPP commissioner must maintain a file of all certificates of transfer at his central office.

Restrictions on Declared LCMs

The bill limits where a person can possess an LCM that was declared. The person may possess it only:


1. at his or her residence, place of business, or other property he or she owns, provided the LCM contains not more than 10 bullets;

2. on the premises of a target range of a public or private club or organization organized to practice target shooting;

3. at a target range that holds a regulatory or business license for practicing target shooting;

4. while on the premises of a licensed shooting club;

5. while transporting the LCM between any of the above-mentioned or to a gun dealer, provided the LCM contains no more than 10 bullets and is transported in compliance with the bill; or

6. under a valid gun permit, provided the LCM (a) is in a handgun lawfully possessed by the person before the bill took effect, (b) does not extend beyond the bottom of the pistol grip, and (c) contains no more than 10 bullets.

A violation of the provision imposing restrictions on declared LCMs is a class C misdemeanor.

Prohibitions and Exemptions from Ban

The bill generally bans the sale, acquisition, or possession of the newly added weapons under similar conditions to the ban on assault weapons under existing law. By law, illegal possession of an assault weapon is a class D felony, with a mandatory minimum one-year prison term. Illegally transferring or carrying an assault weapon is a class C felony, with a two-year mandatory minimum prison term or, in the case of transfers to people under age 18, an additional six-year mandatory minimum. The ban on sales and transfers is effective upon passage.

Legal Possession. Under the bill, anyone who legally possessed one of the newly banned weapons on the day before the bill's effective date and who is eligible for a certificate of possession may continue to do so by applying to DESPP for this certificate by January 1, 2014 and otherwise complying with the bill. A member of the U. S. Military or Navy who is unable to apply by January 1, 2014 because he or she is out of state on official duty has 90 days after returning to Connecticut to apply for a certificate. The certificate must contain a description of the firearm that identifies it uniquely, including all identification marks; the owner's full name, address, date of birth and thumbprint; and any other information DESPP deems appropriate.

Beginning on its effective date, the bill prohibits anyone with a certificate of possession for any of the newly added assault weapons from (1) selling or transferring the weapon in Connecticut to anyone except a licensed gun dealer or (2) otherwise transferring the weapon except by (a) bequest or intestate succession or (b) prior arrangement to DESPP or a local police department. Anyone who inherits an assault weapon for which a certificate was issued has 90 days to apply for a certificate or sell the weapon to a gun dealer, permanently disable it, or take it out of state.

Anyone who moves into Connecticut in lawful possession of an assault weapon has 90 days to make it permanently inoperable, sell it to a licensed gun dealer, or take it out of state. But service members transferred to Connecticut in lawful possession of an assault weapon may apply to DESPP for a certificate within 90 days of arriving here.

Under the law and bill, anyone who possesses an assault weapon for which a certificate has been issued may possess it only at specified locations, such as his or her home or business place, at a licensed shooting club, or at a target range that holds a license for practicing target shooting.

Anyone who obtained a certificate of possession for an existing assault weapon before the bill's effective date for a weapon defined as an assault weapon by the bill is deemed to have obtained a certificate of possession for such assault weapon and must not be required to obtain a separate certificate of possession.

Exemptions

The bill contains exemptions for the newly added weapons as current law contains with regard to assault weapons. It allows the sale and possession of assault weapons to the DOC, DESPP, police departments, and Connecticut's and the U. S. military or naval forces for use in their official duties. It additionally allows sales to and possession by (a) employees of a Nuclear Regulatory Commission (NRC) licensee operating a nuclear power plant in Connecticut for the purpose of providing security or (b) any person, firm, corporation, contractor, or subcontractor providing security at the plant.

It allows possession by employees or members of these entities for official use. And it further specifies that it does not prohibit possession or use of assault weapons by sworn members of these agencies when on duty and within the scope of their duties.

As is the case with assault weapons for which a certificate of possession is issued under existing law, the bill allows the newly added weapons to be possessed or received, under defined circumstances, by:


1. executors or administrators of an estate that includes an assault weapon for which a certificate has been issued,

2. licensed gun dealers, and

3. gunsmiths.

Similarly, it allows for:


1. individuals to arrange to relinquish a weapon to a police department or DESPP;

2. temporary transfers or possession for certain out-of-state events; and

3. the weapons to be transported to or from a shooting competition or exhibition, display, or educational project about firearms sponsored, conducted by, approved, or under the auspices of a law enforcement agency or a national or state-recognized entity that fosters proficiency in firearms use or promotes firearms education


EFFECTIVE DATE: Upon passage


Around the center of the bill I found this regarding PREBAN ASSAULT WEAPONS

BACKGROUND
Assault Weapons
Under existing law, certain assault weapons defined by criteria, rather than specific name, are exempt from the state transfer restrictions and registration requirements if they were legally manufactured before September 13, 1994 (CGS § 53-202m).
The law also allows possession of certain specified assault weapon models under certain circumstances. A person may possess an Auto-Ordnance Thompson type, Avtomat Kalashnikov AK-47 type, MAC-10, MAC-11, or MAC11 Carbine type assault weapon if (1) it was obtained in good faith on or after October 1, 1993 and before May 8, 2002, (2) the possessor is not prohibited from possessing the weapon under any other law, and (3) the possessor notified DESPP before October 1, 2003 that he or she possessed the specific weapon (CGS § 53-202N).

You left out all the parts that would have stopped Sandy Hook...

Well.  Now children have time to run away between mag-changes.

Love the first item on the list of offenses with a deadly weapon:

"Interference with the legislative process. 2-1e(c)"

I thought the law allowed full mags while on your own property or in your residence?

So can I now have an adjustable stock since ill be registering my stripped lowers (which are not named specifically) as AW's?

Yeah, I believe that this is an analysis of the new law, and is not actually the new law, and is misquoted. You can have 30 rounds at home. (Or 12, or 15 as the case may be) OP should edit his post to reflect, then we can indeed pin this.

"  So can I now have an adjustable stock since ill be registering my stripped lowers (which are not named specifically) as AW's? "

I say no. You needed to have possession of it yesterday "day before the law".
If had it yesterday, you were not in legal possession of an assault weapon.
Or I should say, you were in possession of an Illegal assault weapon per the old bill.

You can add a pistol grip to you 8-9-10 shot semi auto shotgun today now.
It seems a normal stock is the same as a pistol grip stock in their eyes now.

MY BRAIN HURTS!!!!!!!

As does my blood pressure. Usually normal, but 300 over 200 when read the bill

So do we have till Jan 1 2014 (Dec 31 2013) to get LCMs? The way I read it is they must be in your possession and a declaration  form filled out by Jan 1 2014. Also will your LGS be able to sell off their inventory of handguns with LCMs with in that time frame?
I wonder how this will affect the semi auto rifle industry being that there are only about 4 currently manufactured semi auto rifles that are no affected by this ban. I guess for those who don't already posses a semi auto center fire rifle, the lever action will be the weapon of choice. Until they try to ban those because someone decided to coin the term Cowboy Assault Rifle.

Welcome to the New World Order

  Sec. 2-1e. Interference with the legislative process; firearms; dangerous or deadly weapons; explosives; felony. (a) A person is guilty of interfering with the legislative process when he, alone or in concert with others, either by force, physical interference, fraud, intimidation or by means of any independently unlawful act, prevents or attempts to prevent any member, officer or employee of the General Assembly, either house thereof or any committee of the General Assembly or either house thereof, from performing any of his official functions, powers or duties.

The transaction had to go through before the bill was signed.

I usually drive right by Sen Don Williams every day on I-384. (Dark ford sedan legislative plate "1" senate pro tempore)

Would flipping him off cause me to lose my guns?

Only if you flip him off 11 times.

 

How about at a private gun range?  

 

so ... benelli m4 doesnt need that cok choker cok ring round limiter?

Right, extend that baby up to 10shells and put a pistol grip on it

Guess not

Since they changed the definition of an "assault weapon" to be anything with a detachable magazine and a pistol grip, any AR is banned now (also by name, type, etc) but does this mean we can have all the banned features we want since it's already banned? Can I add a flash suppressor, etc? I wanted to thread my barrels and that is removed from the definition, so can I now do that? Or do I have to have it abide by the previous law that was in effect when I bought it? Also, they added a forward pistol grip... are we all expected to take off our vertical grips?

As far as pre ban weapons, I think we are OK.


Around the center of the bill I found this regarding PREBAN ASSAULT WEAPONS

BACKGROUND
Assault Weapons
Under existing law, certain assault weapons defined by criteria, rather than specific name, are exempt from the state transfer restrictions and registration requirements if they were legally manufactured before September 13, 1994 (CGS § 53-202m).
The law also allows possession of certain specified assault weapon models under certain circumstances. A person may possess an Auto-Ordnance Thompson type, Avtomat Kalashnikov AK-47 type, MAC-10, MAC-11, or MAC11 Carbine type assault weapon if (1) it was obtained in good faith on or after October 1, 1993 and before May 8, 2002, (2) the possessor is not prohibited from possessing the weapon under any other law, and (3) the possessor notified DESPP before October 1, 2003 that he or she possessed the specific weapon (CGS § 53-202N).


So if I read this correctly anyone with an old AR15 manufactured before September 13, 1994 is free. But if it is named in the above section, then they still must register it as an assault weapon.

Of the preban rifles I currently own:
E.A. CO. J-15 045XXX
OLYMPIC ARMS CAR-AR  AA22XX

FROM  ESSENTIAL  ARMS  WEB SITE:
Essential Arms pre-ban model J-15 lower receivers were machined from heat treated T6 8356 aviation alloy and anodized to mil.spec. 8625. We produced receivers bearing the Essential Arms Company name until 1994. From 1994 through 2002, Essential Arms did machining processes on lower receivers and AR-15 parts for other manufacturers.


Olympic Arms 4-numbers only - very very old. Probably machined from bar stock.
• 1-letter and 4# - older receiver, but forgings. (Some are newer, POST ban castings - call to verify.)
• 2-letters & 4# - most receivers follow this pattern.
• 2#, 2 letters, 4# - the first two #'s are year of manufacture of the lower.
• 2 letters, 6# (separated 2 & 4 - e.g. SA 96 0000) - first 2 #'s are year of manufacture.
• "ICR" marked lowers are an European customer’s overrun, has an unused additional hole - all ICR lowers are post ban.
Olympic Arms Manufacturer’s Notes:
1. There were some odd variations and some custom serial numbers mixed in thru the years also. And, some receivers manufactured after the ban have the year stamp after the model name, not in the serial #. And if you don't see a year stamp on the receiver, it is not necessarily pre-ban.
2. Serial numbers that end in "D" were duplicates and one was changed using this letter.
3. Recently some serial numbers have left with one or two letters followed by FIVE numbers. The last numbers are either 5's or 0's. 99.9% of these are post-ban.
4. "Older" does not always mean pre-ban as per Corey Sattler.
5. "BL" serial number series lowers are transitional with some pre and some post ban. If you have a "BL" you’ll have to call to verify for certain.


(1)THIS IS THE SECTION DEALING WITH CT PREBAN WEAPONS:
Sec. 53-202m. Circumstances when assault weapons exempt from limitations on transfers and registration requirements. Notwithstanding any provision of the general statutes, sections 53-202a to 53-202l, inclusive, shall not be construed to limit the transfer or require the registration of an assault weapon as defined in subdivision (3) or (4) of subsection (a) of section 53-202a, provided such firearm was legally manufactured prior to September 13, 1994

This is what they look like:

so after reading this, my preban PWA is free? i wont have to register it?

You will not have to register it if you did so back in 1994:

Section 28(a)(3) with some edits to make it easily readable:

Any person who obtained a certificate of possession for [a 1993 pre-ban AW] prior to the effective date of this section, that is defined as [a new AW (e.g. one with any "evil" feature")] shall be deemed to have obtained a certificate of possession for such assault weapon [under this new law] and shall not be required to obtain a subsequent certificate of possession for such assault weapon.

I respectfully disagree.

This is the text:

The law also allows possession of certain specified assault weapon models under certain circumstances. A person may possess an Auto-Ordnance Thompson type, Avtomat Kalashnikov AK-47 type, MAC-10, MAC-11, or MAC11 Carbine type assault weapon if (1) it was obtained in good faith on or after October 1, 1993 and before May 8, 2002, (2) the possessor is not prohibited from possessing the weapon under any other law, and (3) the possessor notified DESPP before October 1, 2003 that he or she possessed the specific weapon (CGS § 53-202N).

The pre ban dates of manufacture are a separate issue, as long as the gun is "not named or specified".

My head is starting to spin. I have 3 ARs all manufactured before Sept 1993.  I've purchased them within the last 7 years from  JoJos.
Am I exempt from registering under the new law?

What's the Connecticut Military/Navy?

Did I miss something, or is there no exemption for federal LEOs, only CT LEOs, military, and NRC security/contractors?  While it is arguably implied federal LEOs are covered, it is not expressly stated...interesting.

This will be easy to prove if prebans are still prebans. Find out if Jojos is still selling prebans, or call the state.

Why would SIG Sauer 551-A1, 556, 516" needed to be listed in this bill, didn't the Sig 500 series from first bill cover it?   Don't tell me they were legal and no one knew!

53-202m no longer matters

Why is this?  It references sections 3-4.  There is no longer a section 3 or 4, the text in 53-202a was changed to letters and those sections previously named 3 & 4  were renamed E & F.  Section 53-202m was not updated to match the renaming, and sections 3 & 4 no longer exist...

Therefore there is no longer an exemption on prebans.


When SB 1076 was proposed I saw that 53-202m was not touched and thought the same thing "freebie"  then I read the above text and saw the renaming of those sections.

Bummer

Does this mean the guy's who just blew their wad on pre-bans must convert them to post ban configuration?

no.  other way around


i think



fuck it. gonna just leave shit alone

Damn,everybody's head is spinning......

Ok.  I think I got this...53-202m is gone.

PreBans made prior to Sept 13 1994 but purchased afterward can remain in their original condition.
Post Bans made after Sept 13 1994-April 4 2013 is a semi auto that accepts a detachable magazine and can have 1 evil feature and can remain in their current condition.
Any gun made after April 4 2014...you're fucked.

I need a break from all of this.

not fucked, just gona look ghey with a kalifornia stock on it



or take your regular post bans, put on a kaliforina stock on um, then you wont have to register them.......????

Now you're thinking  




(as long as the lower  isn't banned by name)

im pondering doing this. gona buy one and see how it feels

I need clarification ASAP.  Trying to get some stuff to finish some builds.  

Ya I don't get this either, need a short answer to what we think Pre 94 means.  
Then what post 94 means and how to keep using them.  

I may sell a few Pre 94 bans to mass guys if I don't need them.

I'd really like to get some clarity on what the rules are for our new assault weapons.

Seems to me, an assault weapon is an assault weapon is an assault weapon, and as long as you owned it legally by virtue of it a) not being an assault weapon before or b) it being a preban or otherwise exempted you can keep it (pending registration).

I don't see how any modification going forward can make a newly-christened assault weapon more of an assault weapon, or change the fact that it was owned legally last week.

Can someone point to specific language that prohibits future modification of assault weapons in terms of configuration or features?

Under the former law, non-named prebans were assault weapons, but were exempted from certain registration requirements and prohibitions on transfer. The language referenced in the current bill regarding "prebans" seems to apply to people who registered named models or types. (There may be a few non-named weapons that people obtained certificates of possession for previously, I know of at least one person who claims to have obtained one for a non-Colt AR because he thought he needed to back then)

A lot of currently owned former post-bans have a pistol grip and a forward grip.  I doubt anyone is taking them off.

I think you are right. There is no particular carve-out for assault weapons made between 1993 and 2013 ("post-bans") in the bill. I think that a post-ban can become a pre-ban once it is registered as an assault weapon.
I think.
I also think I would contact an attorney before I did anything.

Sounds like that Nancy Palosi bull shite when she wanted to ban Fox News and the Progressives in the Barry Admin'n to ban American's (excuding Progressives and other lefties) the right to petition government for redress of grievances is the right to make a complaint to, or seek the assistance of, one's government, without fear of punishment or reprisals ...a/o even to silence patriotic Americans from singing our National Anthem like they did in 2010 at the Lincoln Memorial to a group of High School students who were singing and then ORDERED to stop by US Park Police in 2010.

"A group of high school students attending a conservative leadership conference in Washington, D.C. said they were ordered by a security guard to stop singing the national anthem during a June 25 visit to the Lincoln Memorial.
"U.S. Park Police confirmed that the students were in violation of federal law and their impromptu performance constituted a demonstration in an area that must remain “completely content neutral.” http://www.foxnews.com/us/2010/08/09/students-lincoln-memorial-told-stop-singing-national-anthem/

WHAT exactly do they DEEM "Interference with the legislative process"?

Most everything, I imagine. . .

When I statrted this topic I assumed this was the final bill.

But

The final bill (SB1160) was passed and signed into law by the Governor.  It is oficially listed as Public Act 13-3 and is available in full here.

So senate bill 1160 was tweaked a little. It's not accurate. Only review Public Act 13-3

According to the verbiage in the law you had to "legally posses" the assault weapon on the date "prior" to the date of the governor signing the bill. Therefor other than 93 Pre-bans you had to be in compliance with the 2 feature rule. If it doesn't so ply with that it was not "leagelly" purchased. The unfortunately is not a loophole allowing us to modify it how we want. 93 to 3 April 2013 weapons are required to fall within the 2 featur rule.

the old law was ammended though.

and no where in the ammended law does it say that we cant have an adjustable stock, or FH on our new found AWs

Not changing up anything I own until clarification is done on this.
