Converting an AR pistol to a rifle might seem like a complex task, but with the right knowledge, it can be a straightforward process. Here are five legal methods to make your AR pistol into a rifle, focusing on ensuring safety, functionality, and compliance with federal and state laws.
Understand Legal Considerations
Before proceeding with any modifications, it’s crucial to grasp the legal framework:
- Federal Law: Under the National Firearms Act (NFA), if you start with a pistol, you can always revert it back to a rifle configuration.
- State Laws: Many states have their own regulations regarding firearm conversions, so always check local laws before modifying your firearm.
- ATF Rulings: The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) provides guidance on what constitutes a ‘pistol’ versus a ‘rifle.’
Option 1: Adding a Rifle Stock
This is the most straightforward conversion:
- Legal Conversion: Since pistols can be converted to rifles without an ATF approval if they were originally classified as pistols, simply attaching a rifle stock converts your AR pistol to a rifle.
- Stability: A stock increases accuracy by providing a stable platform for shoulder support.
- Recoil Management: Better control over recoil when firing.
💡 Note: Ensure the stock does not change the overall length to exceed 26 inches as per ATF regulations.
Option 2: Installing a Longer Barrel
If you want to retain a pistol grip but increase the length:
- Legal Conversion: Adding a barrel that extends beyond 16 inches, along with a vertical foregrip, legally converts the firearm to a rifle without needing to register it as an SBR.
- Recoil: Less felt recoil with a longer barrel, making for more comfortable shooting.
- Accuracy: Extended sight radius can improve accuracy.
Option 3: Using a Fixed Rifle Buffer Tube
This option keeps the original configuration:
- Legal Conversion: A fixed rifle buffer tube allows for the addition of a traditional rifle stock, turning your AR pistol into a rifle.
- Functionality: The fixed tube retains the original dimensions and design, ensuring compatibility with most AR-15 parts.
Option 4: Changing the Lower Receiver
For those looking for a different lower:
- Legal Conversion: Swapping out the lower receiver for a rifle-specific model also allows for stock attachment.
- Customization: You can choose different features or brands for your lower receiver.
- Cost: Often more expensive but offers new build options.
Option 5: Adding a Foregrip with a Rifle Stock
This option blends elements from above:
- Legal Conversion: Combining a vertical foregrip with a rifle stock transforms the pistol into a rifle.
- Ergonomics: Improves shooting comfort with additional grip options.
- Control: Enhanced control and handling of the firearm.
In summary, converting an AR pistol to a rifle involves understanding legal guidelines, selecting the appropriate conversion method, and ensuring the firearm remains compliant with federal and state laws. Each option offers unique benefits in terms of accuracy, stability, and ergonomics, allowing you to tailor your firearm to your specific needs and preferences. Remember to always verify local laws and ATF regulations to ensure your modifications are legal.
Can I revert my AR pistol back to its original configuration after converting it to a rifle?
+
Yes, as long as the firearm was originally classified as a pistol, you can legally revert it back to a pistol configuration without any special requirements from the ATF.
What are the implications of installing a longer barrel?
+
Installing a barrel over 16 inches combined with a vertical foregrip legally turns your pistol into a rifle, allowing you to avoid SBR classification. This conversion can improve shooting accuracy and recoil management.
Does adding a foregrip change my AR pistol’s legal status?
+
If the foregrip is added to a pistol with a barrel under 16 inches, it could potentially fall under the NFA as an Any Other Weapon (AOW). However, if combined with a rifle stock or a longer barrel, it remains legal as a rifle.
Do I need to inform the ATF when converting my AR pistol to a rifle?
+
No, if you start with a pistol, you can convert it to a rifle or back to a pistol without notifying the ATF. However, ensure you’re complying with state laws, which might differ.
