Assault Weapons Ban in Illinois

The Protect Illinois Communities Act (PICA, 2023, codified at 720 ILCS 5/24-1.9) prohibits the manufacture, sale, transfer, and possession of 'assault weapons.' The definition uses both a named-model list (AR-15, AK-47, and dozens of specified models) and feature tests for semi-auto rifles, pistols, and shotguns. Pre-ban assault weapons owned before January 10, 2023 had to be registered with Illinois State Police by January 1, 2024; unregistered grandfathered firearms are unlawful to possess. The compliance checker applies the full statutory feature test for your specific firearm.

Practical impact: Standard AR-15 and AK-pattern rifles sold in most states are typically prohibited in Illinois. Compliant configurations exist (featureless builds, fixed-magazine variants) but selection is limited. If you are buying a semi-automatic centerfire rifle, run it through the compliance checker before purchase.

Magazine Capacity Limits in Illinois

Illinois prohibits magazines holding more than 10 rounds for long guns and 15 rounds for handguns (720 ILCS 5/24-1.9). Magazines exceeding these capacities cannot be sold, transferred, or possessed.

NFA Items: Suppressors, SBRs, and Machine Guns

Suppressors

Suppressors (silencers) are prohibited for civilian ownership in this state regardless of federal NFA approval. A federal tax stamp does not authorize possession in states where the item is prohibited by state law.

Short-Barreled Rifles (SBRs)

Short-barreled rifles are prohibited for civilian ownership in this state regardless of federal NFA approval.

Machine Guns and Other NFA Items

Pre-1986 transferable machine guns are restricted under the federal Firearm Owners Protection Act and require ATF Form 4 approval. Illinois separately prohibits civilian machine gun ownership.

Permits and Licensing Requirements

Illinois requires a Firearm Owner's Identification (FOID) card for any firearm or ammunition possession or purchase. Application requires a $10 fee, fingerprinting (in some cases), and a background check. The card must be renewed every 10 years.

Carry Laws

Shall-issue concealed carry license available with a 16-hour training course. Open carry is generally prohibited.

Private Sales and Background Checks

Illinois requires all firearm transfers, including private, to be processed with a NICS background check and verification of FOID card status. The seller must keep a record of the transfer for 10 years.

Ghost Guns and Unserialized Firearms

Illinois prohibits unserialized firearms and unfinished receivers under the Combating Illegal Guns Act (720 ILCS 5/24-5.1).

Federally, ATF Final Rule 2021R-05F (effective August 24, 2022) reclassified most unfinished receiver kits as firearms requiring serialization and FFL transfer. State law in Illinois adds additional requirements on top of the federal rule.
