The Illinois assault weapon ban — formally the Protect Illinois Communities Act — has left a lot of gun owners uncertain about what they can legally own, what had to be filed and when, and where the law actually stands after years of litigation. This guide covers what the Act regulates, how the endorsement affidavit process works, what the penalties actually are, and the current legal status as of the most recent federal ruling. If you own or are considering a semi-automatic firearm in Illinois, the details matter more than the headlines.
Important Legal Disclaimer
This article is general information, not legal advice. We are not attorneys. PICA has been the subject of extensive and ongoing litigation, statutory interpretation is contested even among firearms attorneys, and specifics change. Verify current requirements with the Illinois State Police and consult a qualified attorney about your particular situation.
Where Things Stand Right Now
On July 9, 2026, the U.S. Court of Appeals for the Seventh Circuit upheld PICA in a 2–1 decision, reversing a district court ruling that had found parts of the Act unconstitutional after trial.
The law is in effect — and had remained enforceable throughout, because that district court ruling was stayed pending appeal. Separately, a major Second Amendment case testing limits on AR-15-style rifles is headed to the U.S. Supreme Court, which could reshape the landscape. That hasn’t happened yet.

The Illinois Assault Weapon Ban: Essential Facts
The Short Version
What it regulates: Semi-automatic firearms meeting a feature-based definition, a list of named models, large-capacity magazines, and certain attachments.
Signed: January 10, 2023, as Public Act 102-1116, effective immediately as to sale, manufacture, and delivery.
Grandfathering: Existing owners could retain possession of items owned before enactment by filing an endorsement affidavit with the Illinois State Police.
Original affidavit deadline: January 1, 2024 — but the ISP portal remains open. See below.
Magazines: Grandfathered without an affidavit, subject to possession restrictions.
Current status: In effect, upheld by the Seventh Circuit in July 2026.
What Counts as an Assault Weapon Under PICA
The Act uses a feature-based definition rather than a simple list, and that’s the part that catches people out. A firearm can qualify based on its configuration even if the model name doesn’t appear anywhere in the statute.
Semi-Automatic Rifles
A semi-automatic rifle may be regulated if it can accept a detachable magazine and has one or more of the enumerated features. As described in the current federal appellate decision, those include:
- A pistol grip or thumbhole stock
- A protruding grip that can be held by the non-trigger hand
- A folding, telescoping, thumbhole, or detachable stock
- A flash suppressor
- A grenade launcher
- A barrel shroud
A Correction Worth Making
You’ll see published summaries — including an earlier version of this guide — list “muzzle brake or compensator” among the regulated features. The enumerated feature is a flash suppressor, and muzzle devices are not interchangeable terms.
That distinction matters because a reader could otherwise conclude that any muzzle device automatically brings a rifle under the Act. Check the statutory language and the ISP guidance against your specific configuration rather than relying on a paraphrase.
Semi-Automatic Pistols
Similar structure — a detachable magazine plus enumerated features, which include a protruding non-trigger hand grip, a folding or telescoping stock, a barrel shroud, a threaded barrel, and a magazine well located outside the pistol grip.
The Named-Model List
PICA also identifies specific models by name, along with copies and duplicates. The list covers more than 100 named models across rifles, pistols, and shotguns, and the Illinois State Police adopted administrative rules in February 2024 with an appendix identifying regulated firearms.
Don’t Assume Your Firearm Is Outside the Definition
Two things make this harder than it looks. The feature test operates independently of the named list, so a firearm can be regulated without appearing by name. And the ISP’s appendix isn’t necessarily exhaustive — the statutory definition governs.
If you’re uncertain about a specific firearm, the ISP FAQ and a firearms attorney are the right resources. This is not a good area for guessing.
A Federal Change That Doesn’t Help You Here
In spring 2026, the federal government moved to formally rescind ATF’s stabilizing-brace rule following federal court challenges. That rule had classified many braced pistols as short-barreled rifles under the National Firearms Act.
That does not change PICA. Illinois uses a feature-based definition that operates independently of federal classifications, so a change in how ATF treats a configuration doesn’t change how Illinois treats it. This is a common source of confusion.
Magazines and Attachments
The Act reaches beyond the firearms themselves.
Large-capacity magazines. PICA defines a large-capacity ammunition feeding device as one capable of accepting more than 10 rounds for a long gun or more than 15 rounds for a handgun. A 15-round handgun magazine without an extension falls below that threshold.
Grandfathered magazines. Unlike regulated firearms, large-capacity magazines owned before enactment did not require an endorsement affidavit — but PICA limits where grandfathered large-capacity magazines may be possessed. Retaining one lawfully is not the same as being able to carry it anywhere.
Attachments and rapid-fire devices. The Act also regulates certain attachments and devices, with their own penalty structure.
The Endorsement Affidavit Process
This is where the most common misunderstanding lives, because it’s frequently described as “registration” with a fee. The actual mechanism is different — and so is the deadline situation.
Persons who possessed a regulated firearm or firearm attachment before PICA’s enactment were required to complete an endorsement affidavit with the Illinois State Police, stating that the item was possessed prior to January 10, 2023. The ISP affidavit portal opened October 1, 2023, and the original filing deadline for pre-enactment possession was January 1, 2024.
The Portal Didn’t Close — and That’s Important
The original deadline for owners relying on pre-January 10, 2023 possession was January 1, 2024, but the ISP endorsement portal did not close. ISP indicates the portal remains available indefinitely, because PICA provides different filing deadlines for other circumstances — inheritance and moving into Illinois among them.
ISP also indicates there is no separate fine or penalty merely for submitting an affidavit late — while warning that a court or other relevant authority could find a late submission invalid or insufficient.
So the door isn’t simply shut. But filing today doesn’t automatically cure a missed deadline either.
We’re not going to state a filing fee here, because we couldn’t confirm one against current ISP guidance — several secondhand summaries cite figures that don’t appear in the official material. Check the ISP FAQ directly.
If You Missed the Original Deadline
Don’t assume that filing now automatically resolves the problem, and don’t assume it’s hopeless either. The analysis depends on what you own, when and how you acquired it, and your specific circumstances.
This is a conversation to have with an Illinois firearms attorney rather than resolve from an internet guide — including this one.
Transfer Restrictions
Even for properly grandfathered items, transfer options are limited. Generally these include transfer to an heir, to a person outside Illinois who keeps the firearm outside the state, or to a licensed federal firearms dealer.
If a transfer to an FFL is your path, our guide to FFL transfer fees covers what dealers typically charge and what to expect from the process.
Who Is Exempt
PICA includes exemptions for certain categories, including:
- Active law enforcement and their agencies
- Retired law enforcement, including officers covered under the federal Law Enforcement Officers Safety Act
- Military personnel and National Guard in the course of duty
- Corrections personnel
- Armed security at nuclear facilities
- Certain competitive shooters in sanctioned events
- Film and television production under specified conditions
Exemption categories have specific statutory conditions attached, and being generally in one of these groups doesn’t automatically resolve the question. The ISP FAQ addresses several of these directly.
Penalties: What the Statute Actually Provides
This is where a lot of published summaries — including an earlier version of this guide — overstate the exposure, so it’s worth being precise.
First Offense Is Not Automatically a Felony
Current sourcing indicates that possession of a banned assault weapon without proper grandfathering is a Class A misdemeanor for a first offense — up to 364 days in jail and a fine up to $2,500 — and a Class 3 felony for subsequent offenses (2 to 5 years).
Sale or delivery of a banned firearm is a Class 3 felony.
That distinction matters. A first-offense possession charge and a sale charge are not the same exposure, and guides that collapse them into “it’s a felony” aren’t being accurate.
None of which makes this minor. A Class A misdemeanor is a criminal conviction with real consequences for employment, and it puts your FOID card and future firearm eligibility at risk. Attachment violations carry their own penalties.
Verify current penalty provisions before relying on any summary, including this one — penalty structures have been amended in Illinois firearms law before.
The Litigation Timeline
PICA has been through a long and genuinely confusing procedural history. Here’s the sequence that matters.
| Date | What Happened |
|---|---|
| January 10, 2023 | PICA signed as Public Act 102-1116, effective immediately as to sale and manufacture |
| April 2023 | Possession restrictions for grandfathered owners take effect, 90 days after signing |
| August 11, 2023 | Illinois Supreme Court upholds the law in Caulkins v. Pritzker on state constitutional grounds |
| October 1, 2023 | ISP endorsement affidavit portal opens |
| November 2023 | Seventh Circuit upholds the law at the preliminary stage |
| January 1, 2024 | Original endorsement affidavit deadline for pre-enactment possession |
| February 2024 | ISP adopts administrative rules implementing the Act |
| November 2024 | Federal district court rules the bans unconstitutional after trial |
| Seventh Circuit stays that ruling; law remains enforceable pending appeal | |
| July 9, 2026 | Seventh Circuit upholds PICA 2–1, reversing the district court’s merits ruling |
On the state side, the Illinois Supreme Court’s 2023 decision did not reach Second Amendment arguments — those claims had been waived earlier in that case — so the law stood at the state level while federal challenges continued separately.
The July 2026 Seventh Circuit majority concluded that Illinois’s restrictions on assault weapons and large-capacity magazines are consistent with the principles underlying the nation’s historical tradition of firearm regulation, relying in part on the principle that military-style firearms may be treated differently than handguns.
What “Pending Litigation” Does and Doesn’t Mean
Ongoing challenges have not suspended the law. PICA remained enforceable even during the period after the district court’s 2024 ruling, because that decision was stayed pending appeal. A favorable future ruling would not retroactively excuse conduct during the period the Act was in force.
A separate Second Amendment case is headed to the U.S. Supreme Court, and Illinois legislators have introduced bills to modify or repeal portions of the Act. Either could change the picture. Neither has yet.
Realistic Options for Affected Owners
We’re not attorneys and this isn’t legal advice, but these are the paths people in this situation generally consider.
Consult a firearms attorney. If you own regulated items and didn’t file an affidavit, or you’re unsure whether something you own is regulated, this is the first call rather than the last. Illinois firearms attorneys deal with these questions routinely, and the portal remaining open makes the timing question more nuanced than it looks.
Lawful transfer. Transfer to an heir, to someone outside Illinois who keeps the firearm out of state, or to a licensed dealer. Our FFL transfer guide covers the mechanics and typical costs.
Modification. Some firearms can be reconfigured to remove enumerated features. Because the definition is feature-based, this is a real option — but it’s also exactly the area where getting it wrong has consequences, so verify with counsel before altering anything.
Buy compliant. Many firearms remain legal to purchase and own in Illinois, which means the practical question for a new buyer often becomes not whether you can buy a defensive firearm, but which compliant configuration makes sense. Our guides to 9mm handguns and concealed carry guns cover options that generally sit outside the regulated categories — though you should still confirm any specific configuration against the feature test.
Common Mistakes
What Trips People Up
- Assuming enforcement won’t happen. The law is in effect and has survived appellate review. Betting on a future ruling isn’t a compliance strategy.
- Assuming a firearm isn’t covered because it isn’t on the list. The feature test operates independently of the named-model list.
- Confusing muzzle devices. A flash suppressor is an enumerated feature. Not every muzzle device is the same thing under the statute.
- Assuming federal changes carry over. The stabilizing brace rescission is the clearest recent example — it doesn’t affect PICA’s feature-based definition.
- Assuming the affidavit portal closed. It didn’t. That doesn’t mean a late filing cures a missed deadline, but it does mean the situation is worth asking about.
- Overlooking where grandfathered magazines may be possessed. Lawfully retaining one isn’t the same as unrestricted possession.
- Bringing regulated firearms into Illinois when moving. Lawful ownership in a prior state doesn’t transfer.
- Relying on forum advice. Firearms attorneys disagree on some interpretations here. Secondhand summaries — again, including this one — should be verified against the statute and ISP guidance.
Frequently Asked Questions
Is the Illinois assault weapon ban still in effect?
Yes. On July 9, 2026, the Seventh Circuit upheld PICA in a 2–1 decision, reversing a district court ruling that had found parts of it unconstitutional. The Illinois Supreme Court separately upheld the law in 2023 on state constitutional grounds. Further review is possible, but the law is enforceable now — and remained so throughout the litigation, since the district court ruling had been stayed.
Did the endorsement affidavit deadline pass?
The original deadline for owners relying on pre-January 10, 2023 possession was January 1, 2024. But the ISP portal did not close — ISP indicates it remains available indefinitely, because PICA sets different deadlines for circumstances such as inheritance and moving into Illinois. ISP also indicates there’s no separate fine merely for a late submission, while warning that a court could find a late affidavit invalid or insufficient.
What are the penalties for possessing a banned firearm?
Current sourcing indicates possession without proper grandfathering is a Class A misdemeanor for a first offense — up to 364 days and a fine up to $2,500 — and a Class 3 felony for subsequent offenses. Sale or delivery of a banned firearm is a Class 3 felony. Verify current provisions, as penalty structures can be amended.
Does a muzzle brake make my rifle an assault weapon?
The enumerated feature in the statute is a flash suppressor, not muzzle devices generally. Published summaries frequently paraphrase this loosely, which leads people to wrong conclusions in both directions. Check the statutory language and ISP guidance against your specific configuration rather than relying on a summary.
What are the magazine capacity limits?
PICA defines a large-capacity ammunition feeding device as one capable of accepting more than 10 rounds for a long gun or more than 15 rounds for a handgun. A 15-round handgun magazine without an extension falls below the threshold. Grandfathered magazines didn’t require an affidavit, but PICA limits where they may be possessed.
I bought my AR-15 legally before the ban. What now?
If you filed an endorsement affidavit before the January 1, 2024 deadline, you were within the grandfathering process. If you didn’t, the portal remaining open means it’s worth asking an attorney about your options — but don’t assume filing now automatically resolves the issue.
Does the ATF stabilizing brace change affect Illinois?
No. The federal brace rule was rescinded following court challenges in spring 2026, but PICA uses a feature-based definition that operates independently of federal classifications. A configuration ATF no longer treats as a short-barreled rifle may still be regulated under Illinois law.
Can I inherit a regulated firearm?
Transfer to an heir is among the permitted transfer categories, and PICA provides a separate filing deadline for inheritance — one of the reasons the ISP portal remains open. Specific requirements apply to the recipient, so confirm current requirements with the Illinois State Police or an attorney.
What about home-built firearms or 80% lowers?
If a completed firearm meets the statutory definition, how it was manufactured generally doesn’t exempt it. The definition is based on the firearm’s characteristics.
Can I travel out of state with a grandfathered firearm?
Illinois law doesn’t generally prohibit travel with lawfully possessed firearms, but every state you enter has its own rules, and several have their own restrictions on the same categories. Our guide to transporting firearms in Illinois covers the in-state transport rules, and you’ll need to research each jurisdiction on your route.
I’m moving to Illinois. Can I bring my rifle?
PICA provides a filing deadline specific to people establishing residency, which is another reason the ISP portal remains open. That said, the analysis is fact-specific and the consequences of getting it wrong are significant — resolve this before the move rather than after, with the ISP guidance and an attorney.
Do BB guns or airsoft replicas fall under the ban?
PICA applies to firearms. Replicas and air guns aren’t regulated as assault weapons under the Act, though other Illinois provisions may address realistic-looking replicas, and Illinois requires a FOID card for certain air guns above specified thresholds.
Are there bills to repeal or modify PICA?
Bills to repeal portions of the Act and modify the affidavit process have been introduced in the Illinois General Assembly. Introduction is not passage, and predicting legislative outcomes isn’t something we’ll attempt — but the debate is active.
The Bottom Line
The Illinois assault weapon ban is in effect and has now survived review at both the Illinois Supreme Court and the Seventh Circuit. Whatever happens at the U.S. Supreme Court or in the legislature, compliance is measured against the law as it stands today.
Four things are worth getting right. The definition is feature-based, so the named-model list isn’t the whole test — and the enumerated features are specific, not a general description of tactical parts. The penalty structure distinguishes possession from sale, and first-offense possession is not automatically a felony despite what many summaries claim. The affidavit portal remains open, which makes the missed-deadline question worth asking about rather than assuming. And federal changes don’t carry over — Illinois defines these categories on its own terms.
If you own or think you might own something regulated, the Illinois State Police FAQ is the authoritative starting point and a firearms attorney is the right next step. This is not an area where an internet guide, including this one, should be your last word.
