Colorado airsoft gun laws don’t treat these devices as firearms, so there’s no permit, no background check, and no state-set minimum age to own one. The catch is that Colorado’s criminal code reaches airsoft guns through other doors: the “deadly weapon” definition, the “simulated firearm” language in the menacing statute, disorderly conduct rules, school-grounds restrictions, and local ordinances that ban discharging any air-powered gun inside city limits. Get the use right and an airsoft gun is a hobby. Get it wrong and you can be looking at a felony.
How Colorado Classifies Airsoft Guns
Colorado defines a firearm as a handgun, revolver, pistol, rifle, shotgun, or other device capable of discharging bullets, cartridges, or other explosive charges.1Justia Law. Colorado Code 18-1-901 – Definitions Airsoft guns fire plastic pellets with compressed air, springs, or electric motors. No explosive charge, no firearm classification. Concealed carry permits and firearm background check requirements don’t apply.
The term that does matter is “deadly weapon.” Colorado defines it broadly as any weapon, device, instrument, or substance that, in the manner it is used or intended to be used, is capable of producing death or serious bodily injury.1Justia Law. Colorado Code 18-1-901 – Definitions Whether an airsoft gun qualifies depends on context. Pointing one at someone in anger, using one in a robbery, or modifying one to boost its power can all push it into deadly weapon territory, and the sentencing enhancements that come with that finding apply the same way they would to a real gun.
Age and Buying Rules
Colorado has no state statute setting a minimum age to possess an airsoft gun. Most retailers refuse to sell to anyone under 18, but that’s store policy driven by liability concerns, not a state mandate. Minors can generally use airsoft equipment on private property with parental knowledge and consent. Commercial airsoft fields set their own age floors, often 10 or 12 with a signed parental waiver.
Where adults need to pay attention is what happens after they hand the gun over. Under C.R.S. § 18-6-701, anyone who induces, aids, or encourages a person under 18 to violate a state law, municipal ordinance, or court order can be charged with contributing to the delinquency of a minor.2Justia Law. Colorado Code 18-6-701 – Contributing to the Delinquency of a Minor If the minor’s conduct amounts to a qualifying felony, the adult faces a class 4 felony carrying two to six years in prison and up to three years of mandatory parole. For lesser violations the charge drops to a class 1 misdemeanor, punishable by up to 364 days in jail and a $1,000 fine.3Justia Law. Colorado Code 18-1.3-501 – Misdemeanor Penalties Backyard target practice is one thing. Giving a teenager a realistic replica who then uses it to threaten someone in a parking lot is another.
The Orange Tip
Federal law requires every airsoft gun manufactured or sold in the United States to have a blaze orange plug permanently affixed to the muzzle, recessed no more than 6 millimeters from the barrel end. The statute, 15 U.S.C. § 5001, expressly includes air-soft guns firing nonmetallic projectiles in its definition of look-alike firearms.4Office of the Law Revision Counsel. 15 USC 5001 – Penalties for Entering Into Commerce of Imitation Firearms The Consumer Product Safety Commission enforces the marking standards under 16 CFR § 1272.5U.S. Consumer Product Safety Commission. Toy, Look-Alike, and Imitation Firearms Business Guidance
The federal rule binds manufacturers, importers, and sellers. Colorado has no state law requiring you to keep the orange tip on after you buy the gun, and no statute explicitly criminalizes removing it on private land. In practice, keeping the marking intact anywhere outside your home is the cheapest legal insurance you can buy. An officer responding to a “man with a gun” call has no way to tell whether the black object in your hand fires plastic BBs or hollow points, and the consequences of that ambiguity can be fatal long before any courtroom gets involved.
Public Display and Where You Can Shoot
Displaying an airsoft gun in public can draw a disorderly conduct charge under C.R.S. § 18-9-106. The statute makes it illegal for anyone other than a peace officer to display a real or simulated firearm, or any article fashioned to make someone reasonably believe it is a firearm, in a public place in a manner calculated to alarm another person.6Justia Law. Colorado Code 18-9-106 – Disorderly Conduct It’s a class 2 misdemeanor carrying up to 120 days in jail and a fine of up to $750. You don’t have to point the gun or make a verbal threat. An alarmed witness and conduct a reasonable person would find alarming are enough.
Where you can discharge an airsoft gun is largely a local question. Colorado’s constitution grants home rule authority to cities and towns, and several major cities use it to ban air-powered guns outright. Aurora’s municipal code makes it unlawful to fire, shoot, or discharge any BB gun, pellet gun, gas gun, or “any weapon whatsoever” within the city, with narrow exceptions for law enforcement and authorized ranges.7Aurora Municipal Code. Aurora Code 94-146 – Discharge Within City Prohibited; Exceptions; Range Rules Denver has similar restrictions. In those cities, shooting airsoft in your backyard is illegal no matter how safe your setup looks. Check your city’s municipal code before you set up a target in the yard; your city clerk’s office or the city website has the current text.
When Airsoft Becomes a Felony
Under C.R.S. § 18-3-206, a person commits menacing by knowingly placing or attempting to place someone in fear of imminent serious bodily injury through any threat or physical action. Menacing is normally a class 1 misdemeanor. It becomes a class 5 felony when committed with a firearm, knife, bludgeon, or a simulated version of any of those weapons.8FindLaw. Colorado Code 18-3-206 – Menacing
An airsoft gun shaped like a Glock or an AR-15 is the textbook example of a simulated firearm. Pointing one at someone during an argument, waving one in a road rage incident, or using one to intimidate a neighbor can bring a class 5 felony carrying one to three years in prison, two years of mandatory parole, and fines up to $100,000.9Justia Law. Colorado Code 18-1.3-401 – Felony Sentencing It doesn’t matter that the device couldn’t actually kill anyone. The statute cares that it looks like it could.
Schools are the other place where airsoft gets you into felony territory fast. Colorado law prohibits carrying a deadly weapon on the grounds of any public or private school from elementary through college, as well as licensed child care centers. Under C.R.S. § 18-12-105.5, a violation is a class 6 felony.10Colorado Bureau of Investigation. CRS 18-12-105.5 – Unlawfully Carrying a Weapon on School Grounds The statute uses the deadly weapon definition, so an airsoft gun qualifies when the circumstances or its realistic appearance bring it within that definition. Even without a criminal filing, Colorado school districts generally require a full-year expulsion for any student found with a weapon on campus, with modification left to district discretion. Bringing an airsoft gun to school for a costume or a prank is the kind of decision that can derail an academic career.
Transporting Airsoft Guns
Colorado has no statute dictating how to transport an airsoft gun in a vehicle, but a closed, opaque case is the obvious choice. An airsoft gun on a car seat invites police attention during a traffic stop and can support a disorderly conduct charge if a passerby sees it and is alarmed. A locked case removes the ambiguity.
Flying with Airsoft
The TSA treats airsoft guns the same as BB guns and traditional firearms for transport. They go in checked baggage only, never carry-on, unloaded and packed in a locked, hard-sided container.11Transportation Security Administration. BB Guns – What Can I Bring You must declare the item at the airline check-in counter before checking the bag, and you must be at least 18 to check a bag containing one. Individual airlines may add their own requirements, so call your carrier before heading to the airport.
Crossing State Lines
Airsoft rules vary significantly between states. Some impose end-user orange tip requirements that Colorado does not, and a few ban certain replicas outright. If you’re driving to a game in another state, read that state’s rules before you leave. Keeping the orange tip on and transporting in a locked case will keep you out of trouble in most jurisdictions.
Eye and Face Protection
Colorado doesn’t mandate airsoft safety gear by statute, but every commercial field in the state requires full-seal eye protection at a minimum. The gear matters. Standard ANSI Z87 safety glasses are rated for basic impact and are not built for repeated projectile hits at airsoft velocities. Look for ANSI Z87+ (high impact), tested against a steel ball at 150 meters per second, or gear meeting the military ballistic standard MIL-PRF-32432. Plastic lenses degrade with UV exposure and temperature swings, so replace goggles every few years even without visible damage. Most organized fields also require lower-face protection such as a mesh mask, because a BB to the teeth at close range causes real dental damage. Rental packages at commercial fields typically include a mask that meets the facility’s standard.
