The AR-10, a powerful and versatile rifle, has gained immense popularity among firearm enthusiasts for its reliability and customization options. Among the various modifications available, one of the most talked-about upgrades is the AR10 full auto kit. Whether you’re curious about its mechanics, legality, or installation process, this comprehensive guide will address all your questions. Here’s everything you need to know about the AR10 full auto kit.
What Is an AR10 Full Auto Kit?
An AR10 full auto kit is a conversion kit designed to modify a semi-automatic AR-10 rifle into a fully automatic firearm. Semi-automatic rifles fire one round per trigger pull, while fully automatic rifles continue firing as long as the trigger is held down. These kits typically include components like an auto sear, bolt carrier group modifications, and other mechanisms necessary for full-auto functionality.
It’s important to understand that the AR-10 differs from its smaller cousin, the AR-15, as it uses larger-caliber rounds. Converting an AR-10 to full-auto can result in a powerful, fast-firing weapon, which is why these kits have generated so much interest.
How Does an AR10 Full Auto Kit Work?
To transform an AR-10 into a fully automatic firearm, specific internal components must be replaced or modified. Here’s a breakdown of how an AR10 full auto kit works:
1. Addition of an Auto Sear
The most significant component in the kit is the auto sear. This piece interacts with the hammer of the rifle and controls the timing of the firing mechanism, allowing for continuous fire when the trigger is held down.
2. Modified Bolt Carrier Group
A full-auto bolt carrier group (BCG) is often included in these kits. This modified BCG works in tandem with the auto sear to cycle the rifle efficiently, ensuring uninterrupted fire.
3. Adjustments to the Fire Control Group
The fire control group, which includes the trigger, hammer, and disconnector, is adjusted or replaced. These changes facilitate the transition from semi-automatic to full-automatic capabilities.
4. Buffer System Upgrades
Because full-auto firing generates more heat and wear, some kits may include buffer system upgrades to ensure the rifle can handle the increased stress.
Is It Legal to Own an AR10 Full Auto Kit?
One of the most critical aspects of discussing an AR10 full auto kit is its legality. Firearms laws vary significantly across jurisdictions, and owning or installing a full-auto conversion kit comes with legal considerations.
Federal Laws in the United States
Under U.S. federal law, private citizens are generally prohibited from owning or manufacturing new fully automatic firearms. The National Firearms Act (NFA) of 1934 and the Firearm Owners’ Protection Act (FOPA) of 1986 place heavy restrictions on the possession and transfer of automatic weapons. Full-auto conversion kits are often categorized as “machine gun parts,” meaning possessing one without the appropriate licensing can lead to severe legal consequences.
State Laws
Beyond federal regulations, individual states may impose additional restrictions. Some states ban the possession of full-auto parts altogether, while others have more lenient rules for licensed individuals. Always consult your state’s firearms laws before considering an AR10 full auto kit.
Licensing and Exceptions
There are, however, exceptions for certain licensed individuals and entities. To legally own or use a full-auto firearm in the U.S., you must acquire a special license such as a Federal Firearms License (FFL) with the appropriate Class 3 endorsement. Law enforcement and military agencies may also use these kits under strict regulations.
Risks and Drawbacks of Using an AR10 Full Auto Kit
While the concept of owning a fully automatic AR-10 might sound appealing, the practicalities come with significant risks and challenges.
1. Legal Risks
As outlined earlier, improperly owning or installing an AR10 full auto kit can lead to legal trouble, including hefty fines or imprisonment. The strict regulations around these kits make them a risky purchase for the average firearm enthusiast.
2. Wear and Tear
Firing in full-auto mode puts substantial strain on your rifle. Increased heat and pressure can wear out components faster and necessitate more frequent maintenance. This added stress may also lead to safety concerns if the rifle isn’t properly cared for.
3. Reduced Accuracy
Fully automatic rifles are notoriously more difficult to control, particularly with the heavy recoil of an AR-10. While they excel in suppressive fire scenarios, full-auto mode is not ideal for precision shooting.
4. Cost
High-quality kits are costly, and installation requires expertise. Additionally, you’ll likely burn through ammunition quickly when firing in full-auto mode, further driving up your expenses.
Alternatives to an AR10 Full Auto Kit
If you want to enhance your AR-10’s performance without the legal and functional risks of a full-auto conversion, several alternatives are available:
1. Binary Trigger Systems
Binary triggers allow the rifle to fire once when the trigger is pulled and again when it is released. While not fully automatic, this mechanism significantly increases the rate of fire and is legal in many jurisdictions.
2. Specialized Training
Rather than investing in an AR10 full auto kit, consider training to improve your semi-automatic shooting speed and accuracy. Advanced techniques can help you maximize your rifle’s capabilities without legal risks.
3. Custom Components
Upgrading your AR-10 with enhanced optics, barrels, and grips can dramatically improve its performance. These upgrades are entirely legal and allow you to tailor your rifle to your preferences.
How to Use an AR10 Full Auto Kit Safely
If you are legally permitted to own and install an AR10 full auto kit, safety should be your top priority. Here are some tips to ensure safe use:
1. Follow Installation Instructions Carefully
Always use a qualified gunsmith or follow the kit manufacturer’s instructions meticulously. Improper installation can lead to malfunctions or accidents.
2. Regular Maintenance
Full-auto firing generates immense heat and wear. Clean and inspect your rifle frequently to ensure it remains in top working condition.
3. Use Appropriate Ammunition
Stick to high-quality ammunition designed for your AR-10. Avoid using subpar rounds that could cause jamming or other issues during operation.
4. Practice at Certified Ranges
If you’re going to practice full-auto fire, always do so at certified shooting ranges that allow such activities. These environments are designed with safety in mind and help minimize risks.
Where to Buy AR10 Full Auto Kits
Finding an AR10 full auto kit can be challenging due to their restricted nature. These kits are often sold through specialty firearms dealers or manufacturers for law enforcement and military purposes. Always confirm the credibility of the seller and ensure that your purchase complies with all local, state, and federal laws.
Warning About Black Market Purchases
Never attempt to buy kits from unverified or illegal sources. Aside from violating laws, these kits are often of poor quality and can endanger the user.
Final Thoughts
An AR10 full auto kit is undoubtedly a fascinating topic for firearm enthusiasts. However, the legal restrictions, potential risks, and drawbacks make it a highly complex subject. Before considering such a modification, it’s essential to fully understand the laws in your jurisdiction, the challenges of full-auto functionality, and the potential alternatives that could meet your needs without compromising safety or legality.
Ultimately, the AR-10 is a powerful and customizable platform. With thoughtful upgrades and responsible use, you can achieve your shooting goals without resorting to risky or prohibited modifications. Be an informed and conscientious gun owner, and you’ll enjoy the precision, reliability, and adaptability that the AR-10 has to offer.
