What Are the Magazine Capacity Limits in New York?
Woody's answers are based on published federal and state law. Not legal advice. Consult a licensed attorney for your specific situation.
New York limits magazines to 10 rounds for rifles and handguns. This applies to both possession and new purchases statewide.
What This Means for You
New York's magazine restrictions are among the stricter in the nation and directly impact what you can legally build or purchase. The 10-round limit applies to both detachable magazines and fixed magazine systems. You need to verify compliance before completing any build that will be used in New York.
The Detail
New York State law restricts magazine capacity to 10 rounds for both rifles and handguns. This limit applies to detachable magazines as well as fixed magazine configurations. The law covers possession, sale, and transfer of magazines, making it illegal to possess magazines capable of holding more than 10 rounds with limited exceptions for law enforcement and military personnel.
The enforcement mechanism focuses on the physical capacity of the magazine body itself, not just how many rounds you load into it. This means that a standard 30-round AR magazine that's been modified with a limiter or blocker may still be legally problematic if the underlying magazine body retains the capability to hold more than 10 rounds. Many builders address this by purchasing magazines specifically manufactured with 10-round capacity rather than attempting modifications.
Compliance becomes particularly important when building rifles that typically use higher-capacity magazines. Popular rifle platforms often ship with standard capacity magazines exceeding New York's limits, so you'll need to source compliant magazines separately. The law includes both rimfire and centerfire cartridges, so even .22 caliber builds must adhere to the 10-round restriction.
There are specific exemptions for certain activities and personnel, but these are narrow and typically don't apply to civilian builders. The safest approach is to assume the 10-round limit applies to your situation unless you've verified a specific exemption with legal counsel. Always check current New York State official resources for the most up-to-date requirements and any recent changes to the law.
Build Impact
You'll need to source 10-round magazines specifically rather than using standard capacity magazines that come with most rifle kits. This affects both your parts sourcing and potentially your overall build cost since compliant magazines may be more expensive or harder to find.
