The rules in detail

Classification

Treated as firearm

DANGEROUS AMBIGUITY: FOID Act (430 ILCS 65/1.1) defines 'firearm' as any device expelling a projectile by 'explosion, expansion of gas, or escape of gas' — potentially capturing pneumatic and CO₂ airguns.

Age rule

21+ required

If FOID required: 21+, with parental consent under 21.

Possession

Permit required

May require a valid FOID card — including background check, mental health records review, and waiting periods.

Transfer / sale

Firearm-grade process

Transfers may need FOID verification on both sides.

Transport

Cased advised

Cased and unloaded recommended.

Preemption

Notes

IDNR hunting regulations treat 'airgun' as distinct from 'firearm,' adding confusion. No clean statewide hunting-method allowance was captured.

Local rules that still apply

Chicago

Citywide ban on airgun discharge; near-total functional restriction on use.

Federal baseline

Federal statusAir guns are NOT firearms under federal law. 18 U.S.C. § 921(a)(3) defines 'firearm' as a weapon expelling a projectile 'by the action of an explosive.' Air guns use compressed air, CO₂, springs, or gas pistons — outside this definition.

ShippingUSPS explicitly permits airgun shipments under Pub. 52 § 431.7. Pistols and >400 fps require Adult Signature. UPS and FedEx are inconsistent due to internal policy confusion. USPS is the most reliable carrier.

Firearm-frame airgunsAn airgun built on the frame or receiver of an actual firearm (e.g., AR-15 lower) IS a federal firearm regardless of propulsion method, under 18 U.S.C. § 921(a)(3)(B). The marketplace MUST screen for these at listing.
