How to Make an AR15 Full Auto: A Step by Step Guide

In this section, we will discuss the steps involved in making an AR15 full auto. We will cover everything from the legal requirements to the necessary tools and materials.

1. Legal Requirements

Before you start making an AR15 full auto, it is crucial to understand the legal requirements. In the United States, full auto firearms are heavily regulated under the National Firearms Act (NFA). Anyone who wishes to own a full auto firearm must obtain a special license from the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF). Therefore, before you begin, make sure you have all the necessary permits and licenses.

2. Tools and Materials

Making an AR15 full auto requires specific tools and materials. You will need a drill press, milling machine, and hand tools such as a screwdriver, wrench, and pliers. You will also need various sizes of drill bits, end mills, and cutting tools. Additionally, you will need necessary materials such as an AR15 receiver, buffer assembly, sear, and other components.

3. Disassemble the AR15

Before you start modifying your AR15, you must disassemble it. Remove the lower receiver, trigger assembly, bolt carrier group, and charging handle. This step is crucial to identify the necessary modifications.

4. Modify the Lower Receiver

To make an AR15 full auto, you need to modify the lower receiver. The modification involves milling the lower receiver to accommodate the auto sear. This process requires precise measurements and cuts, so you may want to seek professional assistance.

The full auto bolt carrier group is another essential component for making an AR15 full auto. The bolt carrier group must have a milled out rear section to accommodate the auto sear. This process requires precise measurements and cuts, so you may want to seek professional assistance.

8. Test Fire the AR15

Before using your full auto AR15, you must test fire it. This step serves to ensure that the firearm functions as intended. However, make sure you test-fire the weapon in a safe and legal environment.

9. Maintenance and Cleaning

As with any firearm, maintenance and cleaning are essential to ensure longevity and functionality. Therefore, make sure you clean and maintain your full auto AR15 regularly.

10. Conclusion

Making an AR15 full auto is a complex and technical process that requires specific tools, materials, and knowledge. Moreover, owning a full auto firearm is regulated by strict legal requirements. If you do not have the necessary permits and licenses, do not attempt to make a full auto AR15. Safety should always be your priority, and you should always exercise caution when working with firearms.

Section 2: The Legal Landscape of Owning a Fully Automatic AR-15

Ownership of Fully Automatic Weapons in the US

Before making an AR-15 full auto, it’s important to understand the legal implications of owning a fully automatic weapon in the United States. Since 1986, there has been a federal ban on the manufacture and sale of new fully automatic weapons for civilian use. However, there are legal exceptions for certain individuals and organizations to possess fully automatic weapons created before this time.

The National Firearms Act

The National Firearms Act of 1934 regulates the ownership of fully automatic weapons. According to the Act, individuals who wish to possess fully automatic firearms must obtain a class three license from the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF). This license requires an extensive background check, a $200 registration fee, and approval from local law enforcement.

Age and Mental Health Restrictions

Additionally, the National Firearms Act sets age and mental health restrictions on those who are eligible to possess fully automatic weapons. According to the NFA, individuals must be at least 21 years old to apply for a class three license. They must also not have been convicted of any felony crimes or have been committed to a mental institution in the past.

State and Local Regulations

While federal law regulates the possession of fully automatic weapons, state and local regulations can also apply. Some states, such as California and New York, have outright bans on the ownership of fully automatic weapons. It’s essential to understand the firearm laws in your state and locality before attempting to make an AR-15 fully automatic.

Penalties for Non-Compliance

Non-compliance with the National Firearms Act can result in significant legal consequences. Individuals who possess fully automatic weapons without the proper license or registration can face steep fines and imprisonment. The ATF takes non-compliance very seriously and aggressively prosecutes offenders.

Fines and Imprisonment

Depending on the severity of the offense, individuals who are found guilty of possessing fully automatic weapons illegally can face fines up to $250,000 and up to 10 years in prison. Repeat offenders or those who use a fully automatic weapon during a violent crime can face even steeper penalties, including life in prison.

Surrender of Weapons

The ATF has the authority to enforce the surrender of fully automatic weapons from individuals who no longer meet the requirements for possession. Failure to comply with this surrender can result in fines and imprisonment.

Civilian Conversion of Semi-Automatic Weapons

Attempting to convert a semi-automatic weapon to fully automatic without the proper licensing and registration is a federal offense. This act is punishable by as much as 10 years in prison, with no fine imposed. It is crucial to understand the legality behind owning a fully automatic weapon before attempting to create one from a semi-automatic.

Considerations Before Owning a Fully Automatic Weapon

Before attempting to make an AR-15 full auto, it’s vital to think carefully about why one would want to own a fully automatic weapon. The danger associated with these firearms is very high, and the legal responsibilities required for ownership are significant. Consider consulting an attorney familiar with firearms law to understand the legal requirements fully.

Conclusion

It is crucial to understand the legal implications of owning a fully automatic weapon. The National Firearms Act and state regulations significantly regulate the possession and manufacturing of these firearms. Ensure that you comply with all required regulations and consult an attorney before attempting to make a fully automatic AR-15.

Materials Needed for AR15 Full Auto Conversion

Making an AR15 full auto requires some materials that you will need to gather before starting the conversion process. Here are the items needed for your project:

Full Auto Trigger

One of the most important parts of making your AR15 fully automatic is the full auto trigger. You will need to get ahold of a full-auto trigger group for your AR15 rifle. This will replace the standard semi-automatic trigger that came with your rifle.

There are some different variations of full-auto triggers that you can choose from such as a lightning link, drop-in auto sear, and a registered full auto sear. These options can be found online or in gun stores with valid federal firearms licenses.

Full Auto Bolt Carrier Group

The bolt carrier group is another key component that you will need to upgrade when converting your AR15 to full auto. You will need to switch out the semi-auto bolt carrier group with a full-auto version to complete the conversion.

There are a few different options to choose from when searching for a full-auto bolt carrier group. Some of them include phosphate coated steel, chrome plated steel, or nickel boron. Each one offers its own unique set of benefits, so make sure to do some research before selecting one.

Milled Receiver

When converting your AR15 to a full-auto rifle, you will need a milled lower receiver that has an auto sear hole pre-drilled or a billet block that is capable of accepting a auto sear. It is critical to have a lower receiver that is capable of accepting a full auto trigger group.

The vast majority of AR lower receivers you find on the market will be machined from aluminum, or polymer, and come with no sear channel or pre-drilled holes. It is important to ensure that the receiver has the necessary component to make the full auto firing possible.

Bushing the Hammer

Bushing the hammer involves removing the pin that holds the hammer in place and drilling the hole to accept a full-auto sear. Once the hole is drilled and the full-auto sear is installed, the pinhole is then reduced in size, creating a bushing.

Using a bushing stop the hammer from engaging the trigger unless the bolt is fully seated. This extra step is important to have with your full-auto AR15 rifle, as it ensures that the full-auto firing mode is properly contained within the rifle.

Firing Pin Block

The firing pin block is a small piece of metal that will need to be installed in the bolt carrier, stopping it from striking the firing pin unless the trigger is pulled. The firing pin block is needed as a safety mechanism to ensure that the rifle will not accidentally fire when it is being loaded or unloaded.

In conclusion, make sure to purchase all the required items before proceeding with your AR15 full auto conversion. Make sure that you have the knowledge and certification to work on firearms before attempting this project. Remember, a full-auto weapon is illegal unless done properly with the proper registration from the ATF.

That’s All Folks!
