The NY SAFE Act of 2013 redefined "assault weapon" using a one-feature test that is significantly stricter than the previous two-feature test and stricter than the federal assault weapon definitions that expired in 2004[1]. If you want to own an AR-15-platform rifle or similar semiautomatic firearm in New York, you must either build it to be compliant or use a fixed-magazine configuration. This guide explains both approaches.
Understanding the One-Feature Test
Under PL 265.00(22), a semiautomatic rifle is classified as an "assault weapon" if it has the ability to accept a detachable magazine AND possesses at least one of the following features[2]:
- Folding or telescoping stock
- Pistol grip that protrudes conspicuously beneath the action of the weapon
- Thumbhole stock
- Second handgrip or a protruding grip that can be held by the non-trigger hand
- Bayonet mount
- Flash suppressor, muzzle brake, muzzle compensator, or threaded barrel designed to accommodate a flash suppressor, muzzle brake, or muzzle compensator
- Grenade launcher
The critical word is "AND." Both conditions must be present: a detachable magazine capability plus at least one listed feature. Remove either element, the detachable magazine or the prohibited feature, and the rifle does not meet the statutory definition of an assault weapon. This creates two distinct legal paths for building a compliant rifle.
Option 1: The Featureless Build
A featureless build removes all prohibited features while retaining the ability to accept a detachable magazine. This is the most common compliance strategy[3].
Required modifications:
- Fixed stock. Use a stock that does not fold or telescope. An A2-style fixed stock or a permanently pinned adjustable stock must meet that condition.
- No pistol grip. A replacement for the standard AR pistol grip must avoid a pistol grip that protrudes conspicuously beneath the action of the weapon, a thumbhole stock, and a second handgrip or protruding grip that can be held by the non-trigger hand.
- No thumbhole stock. Avoid any stock configuration that allows the thumb to pass through the stock.
- No second handgrip. Do not attach a second handgrip or a protruding grip that can be held by the non-trigger hand.
- No bayonet mount. Remove or avoid any bayonet lug.
- No flash suppressor, muzzle brake, muzzle compensator, or threaded barrel designed to accommodate one. A bare muzzle must have no threads designed to accommodate any of those devices.
Option 2: The Fixed-Magazine Build
A fixed-magazine build permanently affixes the magazine to the rifle, eliminating the "ability to accept a detachable magazine" element of the definition. With a fixed magazine, you can legally retain features like a pistol grip or adjustable stock because the rifle no longer meets both prongs of the test.
Key requirements:
- The magazine must be permanently fixed and not removable without disassembly of the firearm action
- Magazine capacity must not exceed 10 rounds[4]
- Various products exist to convert standard AR-pattern rifles to fixed-magazine configurations (such as the CompMag or similar devices)
Semiautomatic Shotgun Rules
Semiautomatic shotguns have a separate feature test. A semiautomatic shotgun is generally an assault weapon if it has any one of these features. The definition excludes a semiautomatic shotgun that cannot hold more than five rounds in either a fixed or detachable magazine.[5]:
- Folding or telescoping stock
- Thumbhole stock
- Second handgrip or protruding grip for the non-trigger hand
- Fixed magazine capacity exceeding seven rounds
- Ability to accept a detachable magazine
Additional Requirements
- Semiautomatic rifle license: Since September 4, 2022, a license is generally required to purchase or take ownership of a semiautomatic rifle. Applicants must be 21 or older unless honorably discharged from the United States Army, Navy, Marine Corps, Air Force, Coast Guard, or the New York National Guard[6].
- Magazine limit: A feeding device that can accept more than 10 rounds is generally a large capacity ammunition feeding device. The definition excludes specified attached tubular .22-caliber rimfire devices and qualifying registered curios or relics. Possession of a large capacity ammunition feeding device is a Class D felony under PL 265.02(8)[7][8].
- Serialization: New York generally prohibits knowing possession of an unserialized firearm, rifle, or shotgun. The statutory definition of "serialized" excludes antique firearms and firearms, rifles, or shotguns manufactured before 1968.[9]
- No rapid-fire devices: Bump stocks, binary triggers, trigger cranks, and similar devices are prohibited under PL 265.01-c[10].
Choosing the Right Approach
The featureless build is the more popular option because it retains the convenience of a detachable magazine for reloading and cleaning. The fixed-magazine build appeals to shooters who prefer standard ergonomic features like a pistol grip and adjustable stock. Both approaches are legally valid, but each involves trade-offs in usability. Consider which features matter most to you before starting your build or purchase.
Critical Warnings
- Possession of an assault weapon is a Class D felony under PL 265.02(7). The sentence depends on the applicable Article 70 provisions and case-specific facts.
- If you are unsure whether your build is compliant, consult a New York firearms attorney before assembling or purchasing
- Compliance products and configurations change as manufacturers develop new solutions. Verify that any product you buy is specifically marketed as New York SAFE Act compliant
- A rifle that was compliant when you purchased it can become non-compliant if you add a prohibited feature later. Always evaluate the firearm as a complete system
