### What is a Sawed Off AR-15?
A “sawed off AR-15” typically refers to an AR-15 rifle or pistol that has had its barrel shortened to a length that falls below the legal minimums set by the National Firearms Act (NFA). The NFA, enacted in 1934, regulates certain categories of firearms, including short-barreled rifles (SBRs) and short-barreled shotguns. For rifles, a barrel length of less than 16 inches or an overall length of less than 26 inches generally classifies the firearm as an SBR, subject to NFA regulations.
**Defining the Terms:**
* **AR-15:** A semi-automatic rifle based on the ArmaLite AR-15 design. It is chambered primarily in 5.56x45mm NATO (.223 Remington) but can be chambered in other calibers.
* **Short-Barreled Rifle (SBR):** A rifle with a barrel length of less than 16 inches or an overall length of less than 26 inches.
* **National Firearms Act (NFA):** A federal law that regulates certain firearms, including SBRs, suppressors, machine guns, and other items.
### Legal Ramifications: Navigating the NFA
Possessing a sawed off AR-15 without proper NFA registration is a serious federal offense, punishable by significant fines and imprisonment. The NFA requires individuals to register SBRs with the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), pay a $200 tax stamp, and undergo a background check. The process can take several months to complete.
**Key Legal Considerations:**
* **NFA Registration:** Failure to register an SBR can result in severe penalties.
* **State and Local Laws:** In addition to federal laws, state and local regulations may further restrict or prohibit SBR ownership.
* **Constructive Possession:** Even possessing the parts necessary to assemble an SBR can be considered constructive possession and subject to legal penalties.
**The NFA Process:**
1. **Complete ATF Form 1:** Application to Make and Register a Firearm (NFA Form 1).
2. **Submit Fingerprints and Photographs:** Provide fingerprint cards and passport-style photographs.
3. **Pay the $200 Tax Stamp:** Submit payment for the NFA tax stamp.
4. **Wait for ATF Approval:** The ATF will conduct a background check and review the application, which can take several months.
5. **Engrave the Firearm:** Upon approval, the firearm must be engraved with the manufacturer’s name, city, and state.
### Ballistic Performance: How Barrel Length Affects Velocity and Accuracy
Shortening the barrel of an AR-15 significantly impacts its ballistic performance. Shorter barrels result in reduced muzzle velocity, which affects the bullet’s range, trajectory, and terminal ballistics. This is because the powder has less time to burn completely, and the bullet has less time to accelerate within the barrel.
**Key Ballistic Considerations:**
* **Muzzle Velocity:** Shorter barrels lead to lower muzzle velocities, reducing the bullet’s energy and range.
* **Effective Range:** The effective range of a sawed off AR-15 is typically shorter than that of a standard-length AR-15.
* **Accuracy:** While accuracy can be maintained with proper sighting and technique, shorter barrels can be more challenging to shoot accurately at longer distances.
**Velocity Loss by Barrel Length (Approximate):**
* **20-inch Barrel:** Standard AR-15 barrel length, providing optimal velocity for 5.56mm NATO.
* **16-inch Barrel:** A common barrel length, resulting in a slight velocity reduction compared to a 20-inch barrel.
* **10.5-inch Barrel:** Significant velocity loss, impacting range and terminal ballistics.
* **7.5-inch Barrel:** Extreme velocity loss, primarily suitable for close-quarters engagements.
### Tactical Implications: Advantages and Disadvantages of a Sawed Off AR-15
Sawed off AR-15s can offer certain tactical advantages in specific scenarios, primarily due to their increased maneuverability and concealability. However, these advantages come at the cost of reduced ballistic performance and increased muzzle flash and noise.
**Advantages:**
* **Maneuverability:** Shorter barrels make the firearm easier to handle in confined spaces, such as vehicles or buildings.
* **Concealability:** A sawed off AR-15 is easier to conceal than a standard-length rifle, making it potentially suitable for certain law enforcement or security applications (with proper legal authorization).
* **Weight Reduction:** Shorter barrels reduce the overall weight of the firearm, making it easier to carry for extended periods.
**Disadvantages:**
* **Reduced Range and Accuracy:** Shorter barrels significantly reduce the effective range and accuracy of the firearm.
* **Increased Muzzle Flash and Noise:** Shorter barrels result in increased muzzle flash and noise, which can be disorienting and reduce situational awareness.
* **Reduced Terminal Ballistics:** Lower muzzle velocities can reduce the bullet’s effectiveness at stopping threats.
### Alternatives to Sawed Off AR-15s: AR Pistols and Pistol Braces
AR pistols offer a legal alternative to sawed off AR-15s, providing similar maneuverability without requiring NFA registration (in most cases). AR pistols are typically equipped with pistol braces, which are designed to provide additional stability when shooting.
**AR Pistols:**
* **Legal Status:** AR pistols are generally legal to own without NFA registration, provided they meet certain criteria, such as having a barrel length of less than 16 inches and an overall length of less than 26 inches.
* **Pistol Braces:** Pistol braces are designed to attach to the rear of the pistol and provide additional stability when shooting.
* **ATF Regulations:** The ATF has issued rulings regarding the legality of pistol braces, which can be complex and subject to change. It is essential to stay informed about the latest ATF regulations.
### Building vs. Buying: Navigating the Options
Individuals can either build their own AR-15 pistol or purchase a complete AR-15 pistol from a manufacturer. Building an AR-15 pistol requires careful attention to detail and compliance with all applicable laws and regulations. Purchasing a complete AR-15 pistol is generally simpler, but it is essential to choose a reputable manufacturer and ensure the firearm meets all legal requirements.
**Building an AR-15 Pistol:**
* **Lower Receiver:** The lower receiver is the serialized part of the firearm and is considered the firearm itself. When building an AR pistol, it is crucial to start with a receiver that has never been configured as a rifle.
* **Upper Receiver:** The upper receiver houses the barrel, bolt carrier group, and other components.
* **Pistol Buffer Tube:** A pistol buffer tube is shorter than a rifle buffer tube and is designed for use with pistol braces.
**Purchasing a Complete AR-15 Pistol:**
* **Reputable Manufacturers:** Choose a reputable manufacturer with a proven track record of quality and reliability.
* **Compliance with Laws:** Ensure the AR-15 pistol meets all applicable federal, state, and local laws.
* **Warranty and Support:** Look for a manufacturer that offers a warranty and provides good customer support.
### The Importance of Responsible Firearm Ownership
Regardless of the type of AR-15 you own, responsible firearm ownership is paramount. This includes safe storage, proper handling, and ongoing training. Always follow the four rules of firearm safety:
1. **Treat all firearms as if they are loaded.**
2. **Never point the muzzle at anything you are not willing to destroy.**
3. **Keep your finger off the trigger until your sights are on the target and you are ready to shoot.**
4. **Be sure of your target and what is beyond it.**
