Airgun laws by state hinge on one question: does your state’s law call a BB gun, pellet rifle, or CO2 pistol a “firearm”? Federal law does not. Under 18 U.S.C. § 921, a firearm has to expel a projectile “by the action of an explosive,” which leaves air-powered and spring-powered guns outside federal firearms regulation entirely.1Office of the Law Revision Counsel. 18 USC 921 – Definitions States are free to disagree, and several do. A pellet rifle you can order online and shoot in the backyard in one state can require a permit, a background check, or both across the border, and in the strictest places, possessing one without authorization carries the same penalties as an unregistered handgun.
The Federal Baseline
Because airguns aren’t firearms federally, the ATF has no jurisdiction over them. Federal oversight runs through consumer product law instead. The main statute, 15 U.S.C. § 5001, exempts “traditional B–B, paint-ball, or pellet-firing air guns” from the “look-alike firearm” rules that would otherwise require a blaze orange muzzle marking under 16 C.F.R. Part 1272.2Office of the Law Revision Counsel. 15 USC 5001 – Penalties for Entering Into Commerce of Imitation Firearms3Legal Information Institute. 16 CFR Part 1272 – Marking of Toy, Look-Alike, and Imitation Firearms Airsoft guns firing nonmetallic projectiles are not exempt and must carry the orange tip. The marking rules bind manufacturers, importers, and distributors; there is no federal penalty for a consumer who removes the tip later.
The same statute sets one floor states cannot go below: no state may prohibit the commercial sale of traditional air-pressure guns to adults. Everything else — who can own one, at what age, where it can be carried, how it must be stored, whether it needs a permit — is left to the states.
States That Treat Airguns as Firearms
A handful of states pull airguns fully into their firearms code. In those states, every rule that applies to a conventional gun applies to a BB gun.
New Jersey. N.J.S.A. 2C:39-1(f) defines “firearm” to include any air gun, spring gun, or CO2-powered device that ejects a projectile smaller than three-eighths of an inch “with sufficient force to injure a person.”4New Jersey Revised Statutes. New Jersey Code 2C:39-1 – Definitions That definition sweeps in essentially every pellet rifle and BB gun sold. Buying one requires a Firearms Purchaser Identification Card, and unauthorized possession is a third-degree crime carrying three to five years in state prison.
Rhode Island. R.I. Gen. Laws § 11-47-2 similarly folds air rifles, air pistols, and BB guns into the “firearm” definition and applies the state’s full purchase and carry framework to them.5Rhode Island General Assembly. Rhode Island General Laws 11-47-2 – Definitions
States That Set Technical Thresholds
Other states draw a line based on the physics of the gun rather than the category.
Illinois. Under 430 ILCS 65/1.1, a pneumatic, spring, or BB gun escapes the firearm definition only if the projectile is no larger than .18 inch in diameter or the muzzle velocity is under 700 feet per second.6Illinois General Assembly. 430 ILCS 65/1.1 – Firearm Defined An airgun above both thresholds is a firearm in Illinois and requires a Firearm Owner’s Identification Card.
Michigan. Michigan used to treat anything above .177 caliber as a firearm. A 2015 overhaul brought state definitions in line with federal law, so pneumatic and pellet guns are generally no longer firearms under Michigan law.7Michigan Legislature. HB4151 – Analysis as Enacted
Many other states use a “dangerous weapon” or “deadly weapon” middle ground: no permit or background check to buy, but using the airgun to threaten someone or firing it recklessly can trigger the same assault or endangerment charges as a conventional weapon.
What This Means If You Have a Felony Record
The federal ban on felons possessing firearms in 18 U.S.C. § 922(g) tracks the federal firearm definition, so it does not reach airguns.1Office of the Law Revision Counsel. 18 USC 921 – Definitions That is not the end of the analysis. In any state that defines airguns as firearms — New Jersey and Rhode Island most notably — the state prohibited-person law covers them too. A felony conviction plus a BB gun in one of those states is the same charge as a felony conviction plus a handgun, and federal law provides no defense to a state prosecution. Check your state’s firearm definition before you buy.
Age Limits for Buyers and Minors
Federal law sets no minimum age for airgun possession.8Bureau of Alcohol, Tobacco, Firearms and Explosives. Minimum Age for Gun Sales and Transfers States have filled the gap unevenly.
New York bars anyone under 16 from possessing any air gun or spring gun under Penal Law § 265.05, with juvenile delinquency consequences for the minor and a Class A misdemeanor under § 265.10 for the adult who supplied it.9New York State Senate. New York Penal Law 265.05 – Unlawful Possession of Weapons by Persons Under Sixteen10New York State Senate. New York Penal Law 265.10 – Manufacture, Transport, Disposition and Defacement of Weapons and Dangerous Instruments and Appliances
Massachusetts prohibits anyone under 18 from possessing an air rifle or BB gun in any publicly accessible place unless the minor is accompanied by an adult or holds both a sporting or hunting license and a permit from the local chief of police.11General Court of Massachusetts. Massachusetts Code Chapter 269 Section 12B – Air Rifles, Possession by Minors, Shooting Unsupervised teens cannot lawfully walk around with a pellet gun in public without that dual authorization.
Even in states without a blanket possession ban for minors, selling or transferring an airgun to a minor without parental consent commonly carries criminal penalties. Nearly every state also has a parental responsibility statute that can impose civil liability when a child injures someone or damages property with a weapon.12Office of Juvenile Justice and Delinquency Prevention. Parental Responsibility Laws Safe-storage laws for firearms apply to airguns wherever the state definition treats them as firearms.
Where You Can Actually Shoot
Ownership is one problem. Discharge is another, and it’s where most people run into trouble. Nearly every state prohibits firing any projectile weapon within a set distance of a public road or occupied building, and those statutes routinely cover airguns even in states that don’t otherwise regulate them as firearms. Charges range from a disorderly conduct citation to reckless endangerment.
Target shooting on rural private property is legal in most places if you have a backstop that keeps pellets on your land. A pellet that crosses the property line exposes you to trespass and property damage liability. In suburbs and cities the rules tighten fast. Many municipalities ban airgun discharge inside city limits altogether, and local officers can seize the device if they judge the use unsafe.
Buying Online and Private Sales
Because airguns aren’t federal firearms, most online retailers ship them directly to your door. The exceptions are the states and cities that classify airguns as firearms or impose their own shipping rules.
In those jurisdictions, state transfer rules may force the delivery through a licensed dealer. The federal interstate transfer restriction in 18 U.S.C. § 922(a)(5) applies only where the receiving state’s definition of “firearm” is triggered.13Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Major retailers generally will not ship into restrictive states or cities without routing the sale through a dealer.
Private sales run into the same problem. In a state with universal background checks where airguns count as firearms, selling a high-powered pellet rifle to a neighbor without a dealer is a criminal offense. A written bill of sale with the buyer’s name, the date, and a description of the gun is a sensible precaution in any state.
Traveling Across State Lines
Driving across state lines with an airgun means the laws of every state you enter apply to you while you are there. A pellet rifle that is unregulated at home can become an unregistered firearm the moment you cross into New Jersey or Rhode Island. The federal safe-passage protection that covers licensed firearm owners transiting restrictive states does not extend to airguns, because the statute it comes from only covers federally defined firearms.
For flying, the TSA handles pellet guns the same way it handles conventional firearms: banned from carry-on, allowed in checked luggage, unloaded, in a hard-sided locked case, and declared to the airline at check-in.14Transportation Security Administration. Pellet Guns15Transportation Security Administration. Transporting Firearms and Ammunition Airlines can add their own restrictions. On arrival, the destination state and city laws take over.
City Ordinances and Sensitive Locations
More than 40 states have firearms preemption laws that keep cities and counties from going stricter than the state. Whether that preemption covers airguns depends on whether the state defines them as firearms. Where it doesn’t, cities are free to pass their own airgun rules.
New York City is the strictest urban environment in the country for airgun owners. NYC Administrative Code § 10-131(b) makes it unlawful for any person to sell or possess an air pistol, air rifle, or similar spring- or air-powered device within city limits, with narrow exceptions for licensed dealers delivering outside the city, transfers between licensees, and use at authorized amusement venues or shooting ranges.16NYC Administrative Code. Chapter 1 – Public Safety – Section 10-131 Individual possession is effectively banned. Chicago and Philadelphia have also historically layered permit requirements or possession restrictions on top of state law. Check the municipal code before bringing an airgun into any major city in a state without strong preemption.
Weapon-free zones around schools, government buildings, and transit hubs frequently list airguns as prohibited items, regardless of state classification. Bringing a concealed airgun into a school zone can produce felony charges in some jurisdictions. If conventional firearms are barred somewhere, assume airguns are too unless a statute says otherwise.
Hunting Rules Are Separate
State wildlife agencies regulate airgun hunting on their own track, and the rules have expanded over the past decade as air rifle technology has improved. General possession law and hunting law don’t always line up, so hunters need to check both.
Most states allow air rifles for small game like squirrels, rabbits, and certain birds with a valid hunting license, subject to seasonal limits and a minimum caliber that typically runs from .177 for the smallest game up to .22 or .25 for larger species. A hunter education certificate is generally a prerequisite for the license.
Big game hunting with airguns is now allowed in a growing number of states, with much steeper equipment requirements. Texas requires at least a .30 caliber airgun with a 150-grain projectile, a muzzle velocity of at least 800 feet per second, and at least 215 foot-pounds of muzzle energy. Other states set the floor at .35 or .40 caliber with 400 or more foot-pounds. Using an underpowered airgun for big game is a wildlife violation that can cost you your hunting privileges and produce substantial fines. Check the current game commission regulations before the season.
If an Airgun Is Used in a Crime
Federal sentencing enhancements for using a firearm during a violent crime under 18 U.S.C. § 924(c) require a real firearm; airguns, replicas, and toys don’t qualify. That carve-out doesn’t help much at the state level. In states that call airguns firearms, using one in a robbery or assault triggers the same weapons enhancement as a conventional gun.
Even where airguns aren’t firearms, brandishing one during a crime is treated seriously. State assault and robbery statutes often turn on whether the victim reasonably believed they faced deadly force, and a pellet gun or CO2 pistol that looks like a real handgun clears that bar easily. Prosecutors charge armed robbery or aggravated assault in those cases regardless of the device’s actual lethality. The federal orange-tip exemption for traditional airguns provides no cover, because most pellet and CO2 guns look almost identical to their powder-burning counterparts.
