Putting a laser on a gun in California is legal. No state law bans buying, owning, or mounting a laser sight on a handgun, rifle, or shotgun, and you can pick one up at any gun shop or online retailer. What California does regulate is how you use it. Aim that laser at the wrong person, the wrong vehicle, or the wrong animal, and you can face anything from a misdemeanor to a federal felony.
Owning and Mounting a Laser Sight
California has no statute restricting the purchase, possession, or installation of a laser sight on a firearm. Lasers aren’t grouped with accessories the state prohibits. The legal problems start only once the beam leaves the gun and lands somewhere it shouldn’t.
Aiming 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 prove you acted with the specific intent to make a reasonable person fear bodily harm. Sweeping a laser across someone at a range by accident wouldn’t qualify. Deliberately putting the dot on someone’s chest during an argument almost certainly would.1California Legislative Information. California Penal Code 417.25
Two points are worth knowing. The laser doesn’t have to be attached to a gun for the statute to apply, so a handheld pointer used threateningly counts the same way. And the statute explicitly carves out self-defense: aiming a laser sight at someone threatening you falls outside its reach.1California Legislative Information. California Penal Code 417.25
Aiming a Laser at a Peace Officer
Penal Code 417.26 covers law enforcement specifically. Aiming a laser scope or pointer at someone you know, or reasonably should know, is a peace officer, with the intent to make the officer fear bodily harm, is a misdemeanor carrying up to six months in county jail for 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 matters. If you had no way to recognize an undercover officer, that cuts against this charge, though the general provision under PC 417.25 could still apply if the conduct itself was threatening.
Pointing a Laser at an Aircraft
This is where the penalties jump. Under California Penal Code 247.5, deliberately pointing a laser at an occupied aircraft is a wobbler, chargeable as either a misdemeanor or a felony. A misdemeanor 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 act has to be willful and malicious, and it applies whether the aircraft is in flight or on the ground, as long as someone is on board.3California Legislative Information. California Penal Code 247.5
Federal law covers the same conduct separately and more harshly. Under 18 U.S.C. ยง 39A, knowingly aiming the beam of a laser pointer at an aircraft or its flight path is a federal crime punishable by up to five years in federal prison. The same incident can be charged under both state and federal 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 While Hunting
California’s Fish and Game Code prohibits using an artificial light to help take game birds, game mammals, or game fish. The same code bans night vision equipment, infrared lights paired with electronic viewing devices, and battery-powered light-amplifying scopes. The statute doesn’t name laser sights specifically, but the broad “artificial light” language could reach a visible laser used to assist in targeting game. Before relying on a laser sight in the field, check current California Department of Fish and Wildlife regulations for your game and area. A violation can put both your harvest and your 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. These ordinances often treat handheld pointers and firearm-mounted lasers differently, and the specific wording varies. If you live in or pass through a jurisdiction with its own rules, the local code can add requirements that the Penal Code alone doesn’t.
