Putting a laser sight on your gun is legal in California. No state law bans buying, owning, or mounting a laser sight on a handgun, rifle, or shotgun, and they are not lumped in with restricted accessories. The legal trouble starts with how the laser gets used: pointing it at people, peace officers, or aircraft can range from a misdemeanor to a felony, and hunting rules and local ordinances add their own layers.
Owning and Mounting a Laser Sight
California has no statute restricting the purchase, possession, or installation of a laser sight on a firearm. You can buy one at a gun shop or online and attach it to your firearm without violating state law. The rules that follow all deal with conduct, not ownership.
Pointing a Laser at Another Person
Penal Code 417.25 makes it a misdemeanor to point a laser scope or laser pointer at another person in a threatening way, punishable by up to 30 days in county jail. Prosecutors have to show you acted with the specific intent to make a reasonable person fear bodily harm. A laser sweeping across someone at a range wouldn’t meet that bar; deliberately putting a red dot on someone’s chest during an argument would.1California Legislative Information. California Penal Code 417.25
Two points are easy to miss. The laser does not have to be mounted on a firearm for this statute to apply; a standalone pointer used in a threatening way counts. And the statute explicitly carves out self-defense, so aiming a laser at someone who is threatening you falls outside its reach.1California Legislative Information. California Penal Code 417.25
Pointing a Laser at a Peace Officer
Penal Code 417.26 treats the same conduct against law enforcement more harshly. Aiming a laser scope or pointer at someone you know or reasonably should know is a peace officer, with intent to cause fear of bodily harm, is a misdemeanor carrying up to six months in county jail on a first offense. A second or later conviction raises the maximum to one year.2California Legislative Information. California Penal Code 417.26 – Aiming or Pointing Laser at Peace Officer
The knowledge element does real work. If you had no reasonable way to recognize the person as an officer (an undercover officer, for instance), that can be a viable defense to a 417.26 charge, though the conduct could still be prosecuted under 417.25 if it was threatening.
Pointing a Laser at an Aircraft
This is where penalties escalate sharply, and where state and federal law can stack.
California Penal Code 247.5
Willfully and maliciously pointing a laser at an occupied aircraft is a wobbler under state law, chargeable as either a misdemeanor or a felony. A misdemeanor conviction carries up to one year in county jail or a fine up to $1,000. A felony conviction carries 16 months, two years, or three years in state prison, or a fine up to $2,000. The statute applies whether the aircraft is in flight or on the ground, so long as someone is on board, and it defines “laser” as a device exceeding one milliwatt of continuous wave output, which covers essentially every commercial laser sight or pointer.3California Legislative Information. California Penal Code 247.5
Federal Law: 18 U.S.C. 39A
Federal law covers the same conduct with a stiffer ceiling. Under 18 U.S.C. ยง 39A, knowingly aiming the beam of a laser pointer at an aircraft or at its flight path is punishable by up to five years in federal prison. The same incident can be charged under both statutes, and federal prosecutors have pursued these cases aggressively in recent years.4Office of the Law Revision Counsel. 18 U.S. Code 39A – Aiming a Laser Pointer at an Aircraft
Laser Sights and Hunting
California’s Fish and Game Code prohibits using artificial light to help take game birds, game mammals, or game fish, and separately bans night vision equipment, including infrared lights paired with electronic viewing devices and battery-powered light-amplifying scopes. The statute doesn’t name laser sights, but the broad “artificial light” language could reach a visible laser used to assist in targeting game. Before hunting with a laser sight, check current California Department of Fish and Wildlife regulations for your species and area; a violation puts both the harvest and the hunting license at risk.
Local Ordinances
Some California cities and counties regulate lasers beyond what state law requires. A handful of local jurisdictions restrict the sale, possession, or public use of laser pointers through municipal codes, sometimes as an infraction with modest fines. Local rules often distinguish between handheld pointers and firearm-mounted lasers, but the wording varies. If you live in or travel through a city with its own laser rules, those can impose requirements that state law alone does not.
