You can still legally own an AR-15 in New York. What you cannot do is buy the rifle most of the country thinks of as an AR-15, because New York's definition of an assault weapon is one of the strictest in the country.
There are two routes that work: a featureless rifle, or a fixed magazine rifle. Pick one, build it properly, and understand exactly where each one can go wrong.
| Metric | Value |
|---|---|
| Features allowed | Zero |
| Magazine limit | 10 rounds |
| To buy one | License |
| Not the same | CA legal |
The one feature rule
Under the SAFE Act, a semi automatic rifle that can accept a detachable magazine is an assault weapon if it has any one of these:
- A folding or telescoping stock
- A pistol grip that protrudes conspicuously beneath the action
- A thumbhole stock
- A second handgrip or protruding grip for the non trigger hand
- A bayonet mount
- A flash suppressor, muzzle brake or muzzle compensator, or a threaded barrel designed to accommodate one
- A grenade launcher
Note the word any. Many states allow one or two features. New York allows none on a detachable magazine rifle, and a standard AR-15 has several.
The trap: California compliant is not New York compliant
This is the mistake we would most like to prevent.
California's feature list for detachable magazine rifles does not include muzzle brakes, compensators, threaded barrels or bayonet mounts. A California featureless rifle can legally wear a muzzle brake on a threaded barrel.
In New York, that same rifle is an assault weapon. So a rifle marketed as featureless or state compliant, or built from our California guide, is not automatically legal in New York. Check the muzzle and the bayonet lug specifically.
Route one: featureless
A featureless rifle keeps its detachable magazine and removes every listed feature. This is the route that feels most like a normal AR-15 to shoot and reload.
The grip. Replace the pistol grip with a featureless grip or a fin style grip that does not protrude conspicuously, or use a stock that wraps the grip area.
The stock. It must be fixed. A standard fixed rifle stock works, and so does an adjustable stock that is permanently pinned in one position.
The muzzle. This is where New York builds fail. The barrel must be bare, or carry a non functional device that is permanently attached, meaning pinned and welded. A threaded barrel with a removable thread protector is a threaded barrel. Permanently affixing a thread protector over the threads is one approach you will see used.
The front sight base. Many A2 style front sight bases and some barrels include a bayonet lug. That is a bayonet mount, and it is a feature. Use a sight base or gas block without one.
The handguard. No vertical foregrip. Angled grips and similar attachments are an area of varying interpretation, and if you are not certain, leave them off.
A featureless complete lower saves you assembling the stock and grip yourself. Pair it with an upper whose barrel has no muzzle device or threads.
Route two: fixed magazine
A fixed magazine rifle keeps its features, pistol grip and adjustable stock included, because the assault weapon definition only applies to rifles that can accept a detachable magazine.
The condition is strict. The magazine must be permanently fixed and not removable without disassembling the action. You reload by opening the rifle, typically separating the upper from the lower, and loading from the top or swapping the magazine while it is open.
It is slower to reload, and in return the rifle handles like a conventional AR-15. Factory fixed magazine rifles exist, and conversion kits let you modify a lower.
Or buy one built for New York
The simplest route is a complete rifle its maker builds and lists as New York compliant. You still confirm the configuration with your dealer, but you are not assembling the compliance yourself.
Magazines
The limit is 10 rounds, and it applies to both routes. Possessing a magazine that can accept more than 10 rounds is a felony in New York, with narrow exceptions. Buy magazines made as 10 round magazines, and do not keep standard capacity magazines around a New York rifle.
You need a license to buy it
Since 4 September 2022, buying or otherwise newly acquiring a semi automatic rifle in New York requires a semi automatic rifle license, and you must be 21 or older. That applies to a compliant AR-15 exactly as it does to any other semi automatic rifle, including a 9mm carbine.
Start the license process before you buy the rifle. It is the step that sets your timeline.
Which route should you choose?
You want it to feel like a normal AR-15 in the hand. Fixed magazine. You keep the pistol grip and adjustable stock and pay for it in reload speed.
You want normal magazine changes. Featureless. You give up the pistol grip and a muzzle device, and reloads work as normal.
You want the least room for error. A complete rifle built and listed as New York compliant, confirmed with your dealer.
Whichever you choose, the two places New York builds most often go wrong are the muzzle and the bayonet lug. Check both twice.

FAQ
Frequently asked questions
Can you own an AR-15 in New York?
- Yes, if it is not an assault weapon under the SAFE Act. The two legal routes are a featureless rifle, which keeps a detachable magazine but has none of the listed features, and a fixed magazine rifle, where the magazine cannot be removed without disassembling the action. You also need a semi automatic rifle license.
What features are banned on a rifle in New York?
- On a semi automatic rifle that accepts a detachable magazine, any one of these makes it an assault weapon: a folding or telescoping stock, a conspicuously protruding pistol grip, a thumbhole stock, a second handgrip, a bayonet mount, a flash suppressor, muzzle brake, compensator or threaded barrel designed for them, or a grenade launcher.
Is a California compliant rifle legal in New York?
- Not automatically. California's list does not include muzzle brakes, compensators, threaded barrels or bayonet mounts, so a California featureless rifle can have a muzzle brake. In New York that makes it an assault weapon. Check the muzzle and bayonet lug specifically.
Can I have a muzzle brake on a New York AR-15?
- Not on a featureless rifle with a detachable magazine. The barrel must be bare or carry a non functional device that is permanently attached, meaning pinned and welded. On a fixed magazine rifle the feature list does not apply, but confirm the fixed magazine system with your dealer.
What is the magazine limit in New York?
- 10 rounds. Possessing a magazine that can accept more than 10 rounds is a felony in New York, with narrow exceptions. The limit applies to featureless and fixed magazine rifles alike, so buy magazines made as 10 round magazines.
Do I need a license to buy a rifle in New York?
- For a semi automatic rifle, yes. Since 4 September 2022, buying or newly acquiring one requires a semi automatic rifle license, and you must be 21 or older. Start the license process before buying the rifle, since it sets your timeline.
