Colorado airsoft gun laws treat these devices as something other than firearms, so you don’t need a permit or background check to buy one, but the state’s criminal code still reaches airsoft in several important ways. How you carry, display, or use the gun can turn an otherwise legal hobby into a misdemeanor or a felony, and many cities ban discharging air-powered guns within their limits even on private property.
How Colorado Classifies Airsoft Guns
Colorado’s definition of a firearm covers handguns, revolvers, pistols, rifles, shotguns, and other devices capable of discharging bullets, cartridges, or other explosive charges.1Justia Law. Colorado Code 18-1-901 – Definitions Airsoft guns use compressed air, springs, or electric motors to fire plastic pellets, so they sit outside that definition. Concealed carry permits and firearm background checks don’t apply.
The classification that does matter is “deadly weapon.” Colorado defines that 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. Point one at someone during an argument, use one in a robbery, or modify one to increase its power, and the same plastic-pellet gun that was legal on a field an hour earlier can support deadly-weapon sentencing.
The Orange Tip Rule
Federal law requires every airsoft gun manufactured, imported, or sold in the United States to carry a blaze orange plug permanently affixed to the muzzle, recessed no more than 6 millimeters from the barrel end. The statute at 15 U.S.C. § 5001 explicitly names “air-soft guns firing nonmetallic projectiles” as look-alike firearms subject to this marking rule.2Office 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, now codified at 16 CFR § 1272.3U.S. Consumer Product Safety Commission. Toy, Look-Alike, and Imitation Firearm Business Guidance
That mandate is on the manufacturer and seller. Colorado has no separate state law that requires you to keep the tip on after purchase, and no statute explicitly criminalizes removing it on private property. Removing it and then carrying the device where the public can see it is another matter. Officers responding to a report of a person with a gun cannot tell plastic BBs from live rounds. Keeping the orange tip intact whenever the gun leaves your home is the cheapest form of legal protection available.
Age and Giving Airsoft to a Minor
Colorado has no statute setting a minimum age to possess an airsoft gun. Most retailers refuse to sell to anyone under 18 as a matter of store policy, and commercial fields set their own age floors (typically 10 or 12) with a signed parental waiver. Those are private rules, not state law.
The state statute adults need to know about is C.R.S. § 18-6-701, contributing to the delinquency of a minor. Anyone who induces, aids, or encourages a person under 18 to violate a state law, municipal ordinance, or court order can be charged under it.4Justia 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. Lesser violations drop the charge to a class 1 misdemeanor, punishable by up to 364 days in jail and a $1,000 fine.5Justia Law. Colorado Code 18-1.3-501 – Misdemeanor Penalties Backyard target practice with your own kid is one thing. Handing a replica to a teenager who then waves it around in a parking lot is another.
Public Display and Disorderly Conduct
Displaying an airsoft gun in public can bring 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, punishable by up to 120 days in jail and a fine of up to $750.
The statute reaches simulated firearms and anything that causes a reasonable person to believe they’re looking at a real gun. A realistic AR-15 or Glock replica fits that description, particularly if the orange tip is gone. You don’t have to point it at anyone. If someone sees it, is alarmed, and you displayed it in a way a reasonable person would find alarming, the elements are met. Transporting airsoft equipment in a closed case or bag any time you’re outside your home or a sanctioned field is the safe practice.
Menacing and Felony Exposure
This is where the stakes climb. Under C.R.S. § 18-3-206, menacing means knowingly placing or attempting to place another person in fear of imminent serious bodily injury through any threat or physical action. Menacing is normally a class 1 misdemeanor. It escalates to a class 5 felony when committed with a firearm, knife, bludgeon, or a simulated version of any of those weapons.7FindLaw. Colorado Code 18-3-206 – Menacing
An airsoft gun that looks like a real pistol is the textbook example of a simulated firearm. Pointing one at another driver in a road rage moment, brandishing one at a neighbor, or using one to intimidate anyone can support a class 5 felony conviction carrying one to three years in prison, two years of mandatory parole, and fines up to $100,000.8Justia Law. Colorado Code 18-1.3-401 – Felony Sentencing It does not matter that the gun could not actually kill anyone. What matters is that it looked like it could.
The same reasoning applies in robbery and assault cases. If a court concludes the airsoft gun was used as a deadly weapon based on how it was brandished and the fear it created, deadly-weapon sentencing enhancements follow.
Schools and Sensitive Locations
Colorado prohibits carrying a deadly weapon on the grounds of any public or private school, from elementary through college, and at licensed child care centers. Violating C.R.S. § 18-12-105.5 is a class 6 felony.9Colorado Bureau of Investigation. CRS 18-12-105.5 – Unlawfully Carrying a Weapon on School Grounds The statute uses the same “deadly weapon” definition from § 18-1-901, which means an airsoft gun can fall under this prohibition when circumstances suggest it could cause serious bodily injury or when its realistic appearance lets it function as a tool of intimidation.
Recent Colorado legislation has designated government buildings, courthouses, and certain other public facilities as sensitive spaces where firearms are prohibited. Those laws reference firearms rather than airsoft, but carrying a realistic replica into a courthouse or legislative building will trigger an immediate law enforcement response and, at minimum, disorderly conduct or menacing charges.
City Discharge Bans
Colorado’s constitution grants home rule authority to cities and towns, and state statute allows local governments to enact weapons ordinances stricter than state law. Several major Colorado cities use that authority to ban the discharge of air-powered guns within city limits, even on private property.
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 shooting ranges.10Aurora Municipal Code. Aurora Code 94-146 – Discharge Within City Prohibited; Exceptions; Range Rules Denver has similar restrictions. In these jurisdictions, shooting airsoft in your own backyard is illegal no matter how safe your setup looks. Some codes also restrict openly carrying any realistic-looking weapon in commercial districts or on public transit, with penalties that include confiscation and fines. Check your city’s current ordinance through the clerk’s office or the municipality’s website before using airsoft equipment anywhere outside a sanctioned facility.
Transporting Airsoft Equipment
Colorado has no state statute prescribing a specific transport method for airsoft in a vehicle, but a locked case is the obvious choice. An airsoft gun sitting on a car seat invites police attention at traffic stops and can support a disorderly conduct charge if visible to passersby. A closed, opaque case removes the ambiguity.
Flying With Airsoft
TSA treats airsoft guns the way it treats BB guns and traditional firearms for transport: checked baggage only, never carry-on. The device must be unloaded and packed inside a locked, hard-sided container.11Transportation Security Administration. BB Guns – What Can I Bring Declare it at the airline check-in counter before your bag goes on the belt. Individual airlines can add their own requirements, and you must be at least 18 to check a bag containing these items.
Crossing State Lines
Airsoft rules vary a lot between states. Some states and municipalities require end users to keep the orange tip on, and some ban certain replicas outright. If you’re driving to a game in another state, look up that state’s laws before you go. Keeping the orange tip in place and transporting the gun in a locked case will cover you in most jurisdictions.
Eye and Face Protection
Colorado does not mandate specific safety equipment for airsoft by statute, but every commercial field in the state requires full-seal eye protection at a minimum. Standard safety glasses rated ANSI Z87 (basic impact) are not designed for repeated projectile impacts at airsoft velocities. Look for eyewear rated ANSI Z87+ (high impact) or gear meeting the military ballistic standard MIL-PRF-32432.
Plastic lenses degrade over time from UV exposure and temperature changes, so replace goggles every few years even if they look fine. Most fields also require lower-face protection such as a mesh mask, since a BB to the teeth at close range can cause real dental damage. Rental packages at most fields include gear that meets the facility’s safety requirements.
