AR pistols have gained popularity among firearm enthusiasts for their compact size and versatility. One common modification owners often consider is removing the brace. Whether you want to replace it with a different stock or simply prefer the pistol without the brace, this guide will walk you through the process. In this article, we will cover every step of removing the brace from an AR pistol, providing detailed instructions and insights.
1. Gather the Necessary Tools and Equipment
Before you begin, ensure you have all the required tools and equipment at hand. You will need:
- Allen wrench set
- Gunsmithing screwdriver set
- Armor's wrench (for castle nut removal)
- Vise block or padded vise
- Bench vise
- Roll pin punch set
- Hammer
- Lubricating oil
Hence, it is essential to have these tools ready before proceeding with the step-by-step guide.
2. Unload the AR Pistol and Ensure Safety
Safety is paramount when handling firearms. Begin by ensuring the AR pistol is unloaded. Check the chamber, remove the magazine, and make sure there is no ammunition present.
Additionally, you should always wear the appropriate safety gear, such as eye protection and gloves, when working on your firearm.
3. Remove the Buffer Tube
The buffer tube, also known as the receiver extension, is connected to the lower receiver and houses the recoil spring and buffer. Follow these steps to remove the buffer tube:
Step 1: Secure the AR pistol in a padded vise or use a vise block to hold it firmly.
Step 2: Use the armor's wrench to loosen the castle nut. Turn it counterclockwise until it is completely loose.
Step 3: Unscrew the buffer tube by turning it counterclockwise while holding the castle nut.
Step 4: Remove the buffer tube and spring assembly from the lower receiver.
The process of removing the buffer tube may vary slightly depending on the manufacturer and model of your AR pistol. Refer to the specific instructions provided by the manufacturer, if available.
4. Separate the Brace from the Buffer Tube
After removing the buffer tube, you can now separate the brace from it. The method of attachment will depend on the type of brace you have. Most braces are connected using a set screw or a lever system.
Step 1: Locate the attachment mechanism on the brace.
Step 2: Use the appropriate tools to loosen the set screw or release the lever system.
Step 3: Slide the brace off the buffer tube.
Remember to keep all the parts and hardware in a safe place to avoid losing them during the process.
5. Remove the Castle Nut and End Plate
To completely remove the brace and its attachments, you will need to take off the castle nut and end plate. Follow these steps:
Step 1: Use the armor's wrench to loosen and remove the castle nut by turning it counterclockwise.
Step 2: Remove the end plate, which is located behind the castle nut.
By removing the castle nut and end plate, you have successfully taken off all components associated with the brace.
6. Reinstall the Original Stock or Attach a New One
Now that the brace is removed, you have the option to either reinstall the original stock or attach a new one. This step is subjective based on personal preference and the laws and regulations applicable in your area.
If you want to reinstall the original stock, follow the manufacturer's instructions. If you prefer a new stock, ensure it is compliant with the legal requirements of your jurisdiction.
7. Reassemble the Buffer Tube and Lower Receiver
With the stock or new attachment in place, it's time to reassemble the buffer tube and lower receiver. Follow these steps:
Step 1: Insert the buffer tube and spring assembly into the lower receiver.
Step 2: Screw the buffer tube clockwise until it is firmly secured.
Step 3: Tighten the castle nut using the armor's wrench by turning it clockwise.
Ensure everything is properly aligned and tightened, but avoid over-tightening as it may affect the functionality of the firearm.
8. Perform Function Checks and Test Firing
After reassembling the buffer tube and lower receiver, it is crucial to perform thorough function checks before test firing the AR pistol. Ensure the safety is functioning correctly, and the trigger pull and reset are smooth.
When test firing, follow all safety protocols, including selecting a suitable shooting range, wearing hearing protection, and maintaining a proper shooting stance.
9. Regular Maintenance and Cleaning
Keeping your AR pistol in good working condition requires regular maintenance and cleaning. Refer to the manufacturer's instructions for specific maintenance guidelines. It is generally recommended to clean the pistol after each use and perform periodic inspections and lubrication.
10. Legal Considerations and Compliance
Before making any modifications to your AR pistol, always be aware of the laws and regulations concerning firearms in your jurisdiction. Ensure that the changes you make comply with the legal requirements regarding pistol braces, stocks, and other components.
